Programming Example
Nested for Loop in C Programming Language
The way if statements can be nested, similarly whiles and fors can also be nested. To understand how nested loops work, look at the program given below:

#include<stdio.h>
void main()
{
int i;
int j;
for(i = 1; i<=3; i++){
for(j = 1; j<=3; j++){
printf("Welcome ");
}
printf("\n");
}
}Welcome Welcome Welcome
Welcome Welcome Welcome
Welcome Welcome Welcome

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
