Question

I have two variables:

char charTime[] = "TIME";
char buf[] = "SOMETHINGELSE";

I want to check if these two are equal… using charTime == buf doesn’t work.

What should I use, and can someone explain why using == doesn’t work?

Would this action be different in C and C++?

Answer 1

char charTime[] = "TIME"; char buf[] = "SOMETHINGELSE";

C++ and C (remove std:: for C):

bool equal = (std::strcmp(charTime, buf) == 0);

But the true C++ way:

std::string charTime = "TIME", buf = "SOMETHINGELSE";
bool equal = (charTime == buf);

Using == does not work because it tries to compare the addresses of the first character of each array (obviously, they do not equal). It won’t compare the content of both arrays.
