C++ - 实现strcpy函数

#include "stdio.h"

// Copies a string.
//
// strDestination: Destination string.
// strSource: Null-terminated source string.
//
// Returns the destination string.
char * MyStrcpy(char *strDestination, const char *strSource )
{
	char *tmp = strDestination;

	while(*strDestination++ = *strSource++)
		;
	*strDestination = ‘\0‘;

	return tmp;
}

int main(int argc, char* argv[])
{
	char s1[] = "Hello, World!";
	char s2[20];

	MyStrcpy(s2, s1);
	printf("%s\n", s2);
	return 0;
}

// Output:
/*
Hello, World!
*/
