Question

I’m trying to compare a character string with the argv argument.

I have this in my main:

int main(int argc, char *argv[]) 

Now if I write

if (argv[2] == 'squared') 

the IDE tells me that I have a multiple character constant or that the char* is too long for its type or something similiar.

Is there a way to compare argv to a character string? I’ve even used strcmp but that gives me a segmentation fault when the program runs.

I also tried a for loop and incremented argv[i] but that gave me an error too.

Maybe I’m missing something?

Answer 1

Use strcmp and a real string, not a multi character constant.

strcmp(argv[2], "squared") == 0
