Running C scripts with terminal instead of Xcode

Question

Currently I am developing a couple of C programs on my mac using Xcode. There however is 1 problem. My study requires me to use some sort of input field through the coding.

Answer 1

Sounds to me like you want to get your arguments from the command line and if they are missing, prompt the user for them

Lets assume you want the arguments: number word number

#include 
#include 

int number1;
char word[128];
int number2;

int main(int argc, const char **argv)
{
    if (argc == 4)
    {
        number1 = atoi(argv[1]);
        strcpy(word, argv[2]);
        number2 = atoi(argv[3]);
    }
    else
    {
        do
            printf("Enter number word number: ");
        while (scanf("%d %s %d", &number1, word, &number2) != 3);
    }

    printf("I got %d '%s' %d\n", number1, word, number2);
    return 0;
}

Which gives:

$ ./test
Enter number word number: 1 andy 12
I got 1 'andy' 12
$ ./test 2 pandy 56
I got 2 'pandy' 56

Note that the error-checking is poor in this example and can be improved alot (not using atoi() is one way to start).
