How to copy a string using strcpy() function in C

The strcpy() function is a built-in library function, declared in the string.h header file. It copies the source string to the destination string until a null character (\0) is reached.

Syntax

char * strcpy (char * Dest, char * Src);

strcpy() takes two strings as arguments and character by character (including \0) copies the content of string Src to string Dest, character by character.

Let’s look at an example of strcpy():

#include <stdio.h>
#include <string.h>
int main()
{
  char Src[15]= "educative";
  char Dest[15] = "";
  printf("Before copying\n");
  printf("Source string: %s \n", Src);
  printf("Destination string: %s \n\n", Dest);
  
  strcpy(Dest, Src);   // calling strcpy function
  printf("After copying\n");
  printf("Source string: %s \n", Src);
  printf("Destination string: %s \n", Dest);
  return 0;
}
