Question

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?

Answer 1

You’re looking for the function strcmp, or strncmp from string.h.

Since strings are just arrays, you need to compare each character, so this function will do that for you:

if (strcmp(favoriteDairyProduct, "cheese") == 0)
{
    printf("You like cheese too!");
}
else
{
    printf("I like cheese more.");
}
