Defined in header <string.h>
char *strcpy( char          *dest, const char          *src );		(until C99)
char *strcpy( char *restrict dest, const char *restrict src );		(since C99)

Copies the byte string pointed to by src to byte string, pointed to by dest.

If the strings overlap, the behavior is undefined. Also copies the terminating null-byte.

Parameters

dest	-	pointer to the byte string to copy to
src	-	pointer to the null-terminated byte string to copy from

Return value

dest

Example

Run this code

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
int main()
{
    char A[] = "Take the test.";
    char *B = malloc(strlen(A) + 1);
    strcpy(B, A);
    A[0] = 'M';
    printf("A = %s\nB = %s", A, B);
 
    return 0;
}

Output:

A = Make the test.
B = Take the test.
