错误：从不兼容类型'const char *'分配给'char'

Question

I am getting this error when trying to compile my code.

error: assigning to 'char' from incompatible type 'const char *'

The function in reference is

void stringCopy(char *destination, const char *source) {
   while(source != '\0') {
       destination = source;
       destination++, source++;
    }
}

I do know there is a built in strcpy() in C++ but for what I am doing, it was requested that we make one from scratch.

Answer 1

The variable source is a pointer to a character.

The identifier '\\0' is a character .

In the while expression, you are comparing a pointer to a character.

You can get the character by dereferencing the pointer:

while (*source != '\0')

In the copy statement, you are copying pointers, not characters.

Review your favorite C++ reference about pointers.
