How to copy a string into a char array in C++ without going over the buffer

Question

I want to copy a string into a char array, and not overrun the buffer.

So if I have a char array of size 5, then I want to copy a maximum of 5 bytes from a string in

Answer 1

void stringChange(string var){

    char strArray[100];
    strcpy(strArray, var.c_str()); 

}

I guess this should work. it'll copy form string to an char array.
