strcpy

[nguyentrang]

What's the point of the strcpy function?

Since we can do:

char*a = "abc";
char*b;
b = a;

And we can still modify a or b without affecting the other.

Why do we need strcpy?

And we can still modify a or b without affecting the other.

No, you can't. Both a and b point to the same (read-only) array.

char a_modifiable_array[]="abc";
char *a=a_modifiable_array;
char *b=a;
std::cout <<a<<std::endl;
b[0]='A';
std::cout <<a<<std::endl;
