Question

Just a simple problem here: I have a char** argv[] that holds all of my arguments…in one of these arguments, I get an integer proceeded by a %

For example:

bg %2

I really just want the integer….is there an easy way to get this?

This is for homework, so I am willing to do some more digging if anyone can prod me in the right direction.

Thanks

Here is one way to do it using atoi:

for (int i = 0 ; i != argc ; i++) {
    if (argv[i][0] == '%') {
        int num = atoi(&argv[i][1]);
        printf("Got a number: %d\n", num);
    }
}
