Name
strcpy
Synopsis
Copies a string to another location
#include <string.h> char *strcpy
( char * restrictdest
, const char * restrictsrc
);
The strcpy()
function
copies the string addressed by src
to the
char
array addressed by
dest
, and returns the value of its first
argument, which points to the new copy of the string.
There is no limit to the number of characters strcpy()
may write before it encounters a
null character in the source string. It is up to you the programmer
to make sure there is enough storage available to accommodate the
string, including its terminator character. Consider using strncpy()
instead to reduce the risk of
buffer overflows. You must also make sure that the locations that
strcpy()
reads from and writes to
do not overlap.
Example
struct guest { char name[64]; int age; _Bool male, smoking, discount; } this;
int result;
printf( "Last name: " );
result = scanf( "%[^\n]", this.name );
if ( result < 1 )strcpy
( this.name, "[not available]" );
