Syntax
char * strcpy ( char * destination, const char * source );
Description
Copies the C string pointed by source into the array pointed by destination, including the terminating null character (and stopping at that point).
To avoid overflows, the size of the array pointed by destination shall be long enough to contain the same C string as source (including the terminating null character), and should not overlap in memory with source.
Parameters
- destination
- Pointer to the destination array where the content is to be copied.
- source
- C string to be copied.
Return Value
destination is returned.
Example
| Source | Run |
|---|---|
#include <stdio.h>
#include <string.h>
int main(int argc, char *argv[])
{
char hello[10] = "Hello";
char world[10] = "World";
printf("Before strcpy: %s %s\n", hello, world);
strcpy(world, hello);
printf("After strcpy: %s %s\n", hello, world);
return 0;
