Program or Solution

					    
							
#include<stdio.h>
int main()
{
	int i;

Program Explanation

Instruction(s) inside the for block{} are executed repeatedly till the second expression is true.

Here i is initialized to A(65) and incremented by 1 for each iteration, instructions inside the for block are executed unless i becomes greater than Z(90).

so value of i will be printed as character like AB C....Z using printf statement and format specifier %c.
