What is Nested Loop:
-Loop inside loop is called as Nested loop.
Syntax-
loop
{
loop
{
}
}
Why we need nested loop ?
-To performing some task on multiple dimensional data, we need to excess all dimension of the data so that we use the nested loop.
program-
#include< stdio.h>
int main()
{
int i,j,count=0;
for(i=0;i< 2;i++)
{
for(j=0;j< 5;j++)
{
printf("Inside Loop\n");
count++;
}
}
printf("Total %d times loop run",count);
}
output-
Inside loop
Inside loop
Inside loop

Inside loop
Inside loop

Inside loop
Total 10 times loop run
-In this program, we make a nested for loop
-first loop is run 2 times and second loop run 5 times
-so that total runing of loop is 5*2=10
