Solution

The correct answer is 24

EXPLANATION:

#include <stdio.h>

int main() {
    int a, b, c;

    a = 0x10;   // Hexadecimal notation for 16
    b = 010;    // Octal notation for 8

    c = a + b;

    printf("%d", c);

    return 0;
}

0x10 is a hexadecimal representation which is equivalent to 16 in decimal and 010 is an octal representation which is equivalent to 8 in decimal.

So, c = a + b calculates as c = 16 + 8.

Hence, the output will be 24.
