Using pointer like global variables.

[ljo5295]

Hello, I'm trying to make Blackjack game using C.
How should I use pointers like global variables?

For example, if variable named money is on the main function and playing function will increase or decrease money.

I assume you mean something like:

#include <stdio.h>

void func(int *money) {
    *money += 100;
}

int main() {
    int money = 50;
    func(&money);
    printf("%d\n", money);
    return 0;
}

Although you could also do this:

#include <stdio.h>

int func(int money) {
    money += 100;
    return money;
}

int main() {
    int money = 50;
    money = func(money);
    printf("%d\n", money);
    return 0;
}
