To do: Using C++ copy() which copies at most a specified number of characters from an indexed position in a source string to a target character array

To show: How to use the C++ copy() to copy at most a specified number of characters from an indexed position in a source string to a target character array

 

// the char_traits, copy() example

#include <string>

#include <iostream>

using namespace std;

 

int main(void)

{

char_traits<char>::char_type str1[ ] = "abcd-1234-abcd";

char_traits<char>::char_type str2[ ] = "ABCD-1234";

char_traits<char>::char_type* result1;

 

cout<<"The source string is: "<<str1<<endl;

cout<<"The destination string is: "<<str2<<endl;

// note: char_traits::copy is deprecated, consider using char_traits::_Copy_s instead.

result1 = char_traits<char>::copy(str1 , str2 , 4); // C4996 - deprecated

cout<<"The result1 = copy(str1 , str2 , 4) is: "<<result1<<endl;

 

return 0;

}

 

Output example:

 

The source string is: abcd-1234-abcd

The destination string is: ABCD-1234

The result1 = copy(str1 , str2 , 4) is: ABCD-1234-abcd
