Syntax

#include <string.h>
char *strcat(char *string1, const char *string2);

strcat concatenates string2 to string1 and ends the resulting string with the null character.

strcat 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.

If the storage of string1 overlaps the storage of string2, the behavior is undefined.

strcat returns a pointer to the concatenated string (string1).

This example creates the string "computer program" using strcat.

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

#define  SIZE          40

int main(void)
{
   char buffer1[SIZE] = "computer";
   char *ptr;

   ptr = strcat(buffer1, " program");
   printf("buffer1 = %s\n", buffer1);
   return 0;

   /****************************************************************************
      The output should be:

      buffer1 = computer program
   ****************************************************************************/
