Here are some extremely simple programs in C++ for absolute beginner students. I hope these would help them understand how nested loops work in programming. The required pattern of numbers to be printed on screen by a specific program is given before the source code to serve a problem statement.

How i can solve this???
Input a four digit numbers,for exanples 1234. print the number in reverse irder i.e 4321 on dev c++
salam…here is a pattern to solve ur qs4n
#include “stdafx.h”
#include
using namespace std;
int main()
{
int number, reverse = 0;
cout<> number; // Taking Input Number in variable number
for( ; number!= 0 ; )
{
reverse = reverse * 10;
reverse = reverse + number%10;
number = number/10;
}
cout<<"New Reversed Number is: "<<reverse<<endl;
system("pause");
return 0;
}
main()
{
int a,b,c,d;
cin>>a; //1234
b=a/1000;
a=a%1000;
c=a/100;
a=a%100;
d=a/10;
a=a%10;
cout<<a<<d<<c<<b;
}
output:

Nicely written article but it is missing some detailed explanations. If anyone like to see details then they can find it there http://www.hellgeeks.com/loops/
Can anyone do this?
Using For Loop, While Loop and DoWhile Loop, create a program that will ask the user to input any number from 1-99. The input of the user will serve as the starting number of the output until it reach 100.
Sample Output:
Enter number from 1-99: 40
40 41 42 43 44 45 46 47 48 49 50 ……..98 99 100
Would you like to continue? (y/n)
Note: Any input other than 1-99 should be “invalid input” and should ask again to enter number from 1-99. Would you like to continue (y/n)? question should still be posted every after the display of the output numbers. If user input y or Y, display “Welcome back” and go back to main, if n or N display “Thank you” and exit program. Any other input, display “Invalid input” and go back to the question would you like to continue? (y/n)\

Can anyone tell me how to do this example
Design a program that is capable of calculating total of five subjects marks, each of 100 marks. The program will run as long as the user wishes but will work once at least without asking user’s permission.
Use Nested loop to design the program.
The inner loop will calculate total of 5 subject marks. Do not use 5 variables for 5 subjects.
Use outer loop to find if user wishes to continue.
Validate that user enters marks of each subject between 1 to 100
int n=5
int m=n
what does it mean:?
and i and j is not defined in int so how it can be used in loops:???? plzz tell me .,.,., em a beginner
Sorry for late reply Talha.
int N = 5;
defines an integer variable named “N” and sets it equal to 5.
int M = N;
defines another integer variable named “M” and sets it equal to the value of the variable N. As we have just assigned a value of 5 to N, it is equivalent to the following statement:
int M = 5;
But a slight benefit in doing it the way I have done is that, if on a later time, you decide that both M and N should be initialized at a value of 10 instead of 5, then you will have to make this change at one place in your source code. If you define both variables independently then you will have to make that change at two places. This looks like a very small benefit in this simple example. But if you make it your habit to do things in such centralized ways, then you will see that it will save you from a lot of trouble when you move on to reasonably more complex and longer programs.
Now lets look at your second question. Why do you think that i and j are not defined as int variables? They are clearly defined in the first line of their respective for loops. In the parenthesis that follow the “for” keyword, you are allowed to put any three C++ statements separated by semicolons. There is no restriction from compiler on what kind of operations could be performed in those statements. Therefore, in these examples, I am defining variables in first of those three statements.
Hope it helps. Thanks for visiting and best of luck for your newly started programming journey 🙂

First try it yourself. Post what you have come up with here. Then I will correct any mistakes or errors that you might have in your code. In this way, you will learn much more than simply copying the code 🙂

how to print this
well … make the outer loop iterate for 6 times, and the inner loop to iterate for 2 times in first iteration of the outer loop and progressively reach 7 iterations by the last iteration of the outer loop. Place a check (if statement) in the body of inner loop that prints an underscore (_) if it is the last iteration of the inner loop and a pipe (|) otherwise.
I hope these hints will be enough for you to write your required program. Try your best and If you are still confused about some specific step then paste the code that you are able to come up with here and I shall try to correct any of your mistakes 🙂

I can’t detect some regular pattern in these lines. can you please tell in some more detail what could be some other legitimate outputs. Then I may be able to help you better.
if it has some white spaces on the left side of lines which are not showing here, then please repost it by enclosing it within

tags.
Thanks
this is the continuation:
for (int l=(N-1)/2; l>=1; l–) //l=line number after mid to end in descending order after mid.
{ //so if line mid=3, the line after it is line 2 and then line 1.
for (int s=1; s<=space_2; s++) //s=spaces on each line l.
cout<<" ";
for (int a=(space_2)+1; a<=(N-space_2); a++) //a=place os asterisks on each line l.
cout<<"*";
cout<=1; l–) //l=line number after mid to end in descending order after mid.
{ //so if line mid=3, the line after it is line 2 and then line 1.
for (int s=1; s<=space_2; s++) //s=spaces on each line l.
cout<<" ";
for (int a=(space_2)+1; a<=(N-space_2); a++) //a=place os asterisks on each line l.
cout<<"*";
cout<<endl;
space_2+=1; //updating space_2.
}
But the shape above is ot how i meant it. i meant them to be aligned in the middle.
thank you.
humm .. looks nice. good effort! however I was not able to compile your program mainly due to this line:

el hamdulellah using this code, it was printed but I don’t know if there’s a simpler way because it seems complicated:
int mid=(N+1)/2; //the line in the middle of the rhomboid.
int space=(N-1)/2; //the number of spaces before the ‘*’. Is to be used for line 1 of the rhomboid to line mid.
int space_2=1; //to be used for spaces before’*’ for lines after line mid untill the last line.
for (int l=1; l<=mid; l++) //l=line number from 1 to mid.
{
for (int s=1; s<=space; s++) //s=spaces on each line l.
cout<<" ";
for (int a=space+1; a<=(N-space); a++) //a=place of asterisk on each line 1.
cout<<"*";
cout<<endl;
space-=1; //updating space.
}
Yes .. I shall try my best to help you. Can u please tell me for a given value of N, say N=5, what should be the output of this program?? I mean the correct output as asked in the problem statement. Currently for N=5 it prints 5 lines containing 5 asterisks each like this:

please help
Have you attempted it yourself?? what specific problem do you have??
Pease first show me what you have come up with and then I shall try my best to help you correct your mistakes 🙂
However if you don’t know how to generate successive alphabets in a program then I can give you a hint in this regard.
Alphabets ‘A’ to ‘Z’ correspond to ASCII values 65 to 90 respectively. It means that if you assign a number in this range to a variable of type ‘char’ and then output this variable to screen then the alphabet corresponding to that number will be printed.
Look at this simple example program. It prints all capital alphabets from ‘A’ to ‘Z’ on the screen.
char ch;
for ( int i=65; i<=90; i++ ) { ch = i; cout << ch << endl; } Now that you have the fundamental skill to get the required output, please try to design the required nested loops yourself and in case of any problem show me your code and I shall try to help you 🙂 Thanks for visiting though!!

0n every sample pr0gram,
Why those i&j were n0t declared ,, it could have a error’ runing the program!
Hi nathaniel,
can u see the statements like int i=0, int j=0 as the first statements in the corresponding for loops?? They are actually declarations of these variables. the first of three statements in a for loop’s header is executed once at the beginning of the loop. so it causes the variable to be declared, defined and initialized properly before it is used so it doesn’t cause any error in the execution of the program. Hope you got it. if you still have any confusion then please follow back!!
Thanks for the comment.

You have a mistake in your 3rd example, N should be 5.
oh yes … and thank you very much for mentioning. i have just corrected it. Actually before writing this post, I was experimenting with my these programs to check whether they work as expected for other values of N, too. Probably i copied the source code in such a situation.
Anyhow, I am sorry for the mistake and thank you for indicating it!!!!!!!
