What is the output of following C program?

#include <stdio.h>

main()

{

                int i, j, x = 0

                for (i = 0; i < 5; ++i)

                for (j = 0; j < i; ++j)

                {

                x + =(i + j – 1);

                break;

                }

Answer 1

Loop evaluation

for i = 0	j = 0	j not less i, inner for loop terminates
for i = 1	j = 0	x = 0 + 1 + 0 – 1 = 0 break statement encountered, inner loop terminates
for i = 2	j = 0	x = 0 + 2 + 0 – 1 = 1 break statement encountered, inner loop terminates
for i = 3	j = 0	x = 1 + 3 + 0 – 1 = 3 break statement encountered, inner loop terminates
for i = 4	j = 0	x = 3 + 4 + 0 – 1 = 6 break statement encountered, inner loop terminates
for i = 5	i not less 5, outer loop terminates
