C - Nested loop

Nested loop is a loop inside another loop. Nested loop is useful when you want to print numbers in rows and columns.

Example 1: Nested for loop.

for (i=1; i<=10; i++)
	for (j=1; j<=10; j++)
		printf("%d\n", a++);

The above code will execute upto 100 times.

Same way you can nested while and do_while loop.

Multiple initializations in for loop

for (i=1,j=1; j<=10; i++, j++)
	printf("%d %d\n", i, j);
