    If you have written something, then what is your current code and how does it not work?

    If you have not yet written anything, then what is your plan to proceed, and what problems are you having with it?

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    The general idea of forums like this one is that help is provided for specific questions or problems. Your statement isn't a question, and if it was a question it still wouldn't be specific. So, the idea is that you present somecode that you've written that's giving you problems or not behaving as you'd expect and ask a specific question about it.

    Comparing strings is usually done by including string.h and using the strcmp() function.

    Code:
    int i;
    char string1={"Bob"}, string2={"Chris"};
    
    i=strcmp(string1, string2);
    
    if(i<0)
        printf("string1 is less than string2\n");
    else if(i==0)
       printf("strings are the same\n");
    else //i>0
       printf("string1 is greater than string2\n");
    The return is always relative to string1. Low return (<0), string1 is lower than string2. High return (>0), string1 is higher, etc.

    Does C or C++ know to make them arrays?

    Code:
    char string1={"Bob"}, string2={"Chris"};
    Instead of the normal
    Code:
    char string1[]={"Bob"};
    char string2[]={"Chris"};
