What will be the output of the following code snippet?
#include <stdio.h>
#define VAL 3 * (2 + 6)
void solve() {
    int a = 10 + VAL;
    printf("%d", a);
}
int main() {
    solve();
    return 0;
}
  • a)
    104
  • b)
    24
  • c)
    10
  • d)
    34

The above code snippet shows the use of macros in C. The expression for VAL is directly put in its place in the code at compile-time and then the expression is evaluated, which gives a value of 34.

What will be the output of the following code snippet?#include <std...


Explanation:

Macro substitution:
- The macro VAL is defined as 3*(2+6).
- When the macro is substituted, it becomes 3*(8) which equals to 24.

Value of 'a':
- In the function solve(), a is calculated as 10 + VAL.
- Substituting the value of VAL (which is 24), we get a = 10 + 24 = 34.

Output:
- The final value of a is 34.
- So, the output of the code snippet will be 34.
