C: why are extra semicolons OK?

Question

#include 

int main() {
    int a = -1, b = -10, c = 5;
    if (a > b)
        printf(\"Hello World\");
    else
        printf(\"Get out World\");;;;;         


        

Answer 1

It's a null statement which you have after the printf() statment. Having more than one semi-colons is allowed.

C11, §6.8.3, 4

A null statement (consisting of just a semicolon) performs no operations
