[c] How to compare strings in an "if" statement?

I want to test and see if a variable of type "char" can compare with a regular string like "cheese" for a comparison like:

#include <stdio.h>

int main()
{
    char favoriteDairyProduct[30];

    scanf("%s",favoriteDairyProduct);

    if(favoriteDairyProduct == "cheese")
    {
        printf("You like cheese too!");
    }
    else
    {
        printf("I like cheese more.");
    }

    return 0;
}

(What I actually want to do is much longer than this but this is the main part I'm stuck on.) So how would one compare two strings in C?

Have a look at the functions strcmp and strncmp.

if(strcmp(aString, bString) == 0){
    //strings are the same
}

You can't compare array of characters using == operator. You have to use string compare functions. Take a look at Strings (c-faq).

The standard library's strcmp function compares two strings, and returns 0 if they are identical, or a negative number if the first string is alphabetically "less than" the second string, or a positive number if the first string is "greater."

if(!strcmp(favoriteDairyProduct, "cheese"))
{
    printf("You like cheese too!");
}
else
{
    printf("I like cheese more.");
}
