Question

I used the strcpy() function and it only works if I use C-string arrays like:

char a[6] = "text";
char b[6] = "image";
strcpy(a,b);

but whenever I use

string a = "text";
string b = "image";
strcpy(a,b);

I get this error:

functions.cpp: no matching function for call to strcpy(std::string&, std::string&)

How to copy 2 strings of string data type in C++?

Answer 1

You shouldn’t use strcpy() to copy a std::string, only use it for C-Style strings.

If you want to copy a to b then just use the = operator.

string a = "text";
string b = "image";
b = a;
