Defined in header <cstring> | ||||
---|---|---|---|---|
|
Copies the character string pointed to by src
, including the null terminator, to the character array whose first element is pointed to by dest
.
The behavior is undefined if the dest
array is not large enough. The behavior is undefined if the strings overlap.
Parameters
dest | - | pointer to the character array to write to |
src | - | pointer to the null-terminated byte string to copy from |
Return value
dest
.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 | #include <iostream> #include <cstring> #include <memory> int main() { const char * src = "Take the test." ; // src[0] = 'M'; // can't modify string literal auto dst = std::make_unique< char []>(std:: strlen (src)+1); // +1 for the null terminator std:: strcpy (dst.get(), src); dst[0] = 'M' ; std::cout << src << '\n' << dst.get() << '\n' ; } |
Output:
1 2 | Take the test. Make the test. |
