Take user input between 1 and 10 and print out the number as a word, using a function

[JaAnTr]

Hi, I'm new to C, but not programming in general, but am struggling to get my head around functions. I'm working my way through some C exercises to get some practice and have hit a wall. I need to use a function to take a number, such as 1, and print out One.

Here's what I've got so far:

#include <stdio.h>

int name(int n);
char numberOne[] = "One";
    

int main(void)
{
    int n;
    
    scanf("%d", &n);
    
    if (n>=0 && n<10) name(n);
    else printf("Error: number (%d) out of range\n", n);
    
}


int name(int n){
    if(n == 1){
        printf("%s", numberOne);
        return 0;
    }else{
        printf("Got here");
        return 0;
    }
}

However, when I run the code and enter "1" the only thing that gets printed to the screen is "(lldb)". I've tried changing it to doing it without variables and just printing "One" but that gave the exact same result. I can't work out why this is, any help would be greatly appreciated.

Thanks!

Do you get the same result if you replace the line

printf("%s", numberOne);

with

printf("%s", "One");

??

Yes, it still just prints (lldb).

Edit: Just tried compiling it in terminal and running it from there and it now works fine. It doesn't work in XCode though, that was my issue. Any idea why that is?

(lldb) is the prompt for the debugger, maybe it's happening because your program crashed somewhere. You could try running the program step by step from within XCode and see where this happens? I don't use it but some other threads commented on this with XCode so maybe there is an implementation problem:

Works on my Xcode.
Maybe copy this, then start a new project and paste the code into that.

Judging from the OP, I hope it's not your intention, JaAnTr, to use if-else statements to do your printing.

Instead, I would use an array of strings. For example,

str_array[0] = "zero";
str_array[1] = "one";
str_array[2] = "two";

/* ... */

str_array[10] = "ten";

Sorry, like I said I'm quite new to C. What is wrong with the way I've done it and how do I do it your way, I don't fully understand.

Thanks!
