Function Pointer Dispatch Table

Code

#include <stdio.h>

int add(int a, int b) { return a + b; }
int sub(int a, int b) { return a - b; }
int mul(int a, int b) { return a * b; }
int divide(int a, int b) { return a / b; }

typedef int(*function_ptr)(int,int);
function_ptr x=add;
int execute_command(int a, int b, int cmd) {
    // Your logic here using function pointer array
    function_ptr opperation[]={add,sub,mul,divide};
    return opperation[cmd](a,b);
}

int main() {
    int a, b, cmd;
    scanf("%d %d %d", &a, &b, &cmd);

    int result = execute_command(a, b, cmd);
    printf("%d", result);

    return 0;
}
