Find the Output: Triangular nested-loop differences

14Find the output of the following C code (assume #include <stdio.h> and that the code is inside int main(void)):
int i, j, count = 0;
for (i = 1; i <= 4; i++) {
    for (j = i; j <= 4; j++)
        count += j - i;
}
printf("%d", count);
  • Option : B
  • Explanation : The outer iterations add 6, 3, 1, and 0, giving 10.
