char*strcpy(char*dest,constchar*src);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
Run this code
#include<cstring>#include<iostream>#include<memory>intmain(){constchar*src="Take the test.";// src[0] = 'M'; // can't modify string literalautodst=std::make_unique<char[]>(std::strlen(src)+1);// +1 for null terminatorstd::strcpy(dst.get(),src);dst[0]='M';std::cout<<src<<'\n'<<dst.get()<<'\n';}Output:
Take the test. Make the test. See also
