Function Pointer Dispatch Table

Func pointer -> ret_type (*name)(inputs);

#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; }

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

Solving Approach

    int (*func[])(int, int) = {add, sub, mul, divide}; is the syntax
