Format
#include <string.h> char *strcpy(char *string1, const char *string2);
Language Level: ANSI, POSIX, XPG4
strcpy copies string2, including the ending null
character, to the location specified by string1.
strcpy operates on null-terminated strings. The string arguments to the function should contain a null character (\0) marking the end of the string. No length checking is performed. You should not use a literal string for a string1 value, although string2 may be a literal string.
Return Value
strcpy returns a pointer to the copied string (string1).
Example
This example copies the contents of source to
destination.
#include <stdio.h> #include <string.h>
#define SIZE 40
int main(void)
{
char source[ SIZE ] = "This is the source string";
char destination[ SIZE ] = "And this is the destination string";
char * return_string;
printf( "destination is originally = \"%s\"\n", destination ); return_string = strcpy( destination, source ); printf( "After strcpy, destination becomes \"%s\"\n", destination ); return 0;
/*******************************************************************
The output should be similar to:
destination is originally = "And this is the destination string"
After strcpy, destination becomes "This is the source string"
