Answer 1

Theoretically the answer should be:

int op_type(const char *input, int op_pos)
{
    int category;
    switch (input[op_pos]){
        case '+':
             category = 1;
             break;
        case '*':
             category = 2;
             break;
        case '/':
             category = 3;
             break;
        case '^':
             category = 4;
             break;
    }
    return category;
}
