strcpy()

The strcpy() function copies one string into another string, and returns the newly copied string.

#include <string.h>

strcpy(string1, string2);

At the top of the file, the <string.h> header file needs to be included. The strcpy() copies string2 parameter into string1, including the terminating null character ('\0').

Suppose we have two strings, pokemon1 and pokemon2:

#include <stdio.h>
#include <string.h>

int main() {
  char pokemon1[30] = "Ditto";
  char pokemon2[30] = "Pikachu";

  // This function has copied pokemon2 into pokemon1
  strcpy(pokemon1, pokemon2);

  printf("pokemon1 is now: %s", pokemon1);
  return 0;
}

The output would be:

Pikachu
