strcpy library c++ code example

Example 1: strcpy

/* strcpy example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char str1[]="Sample string";
  char str2[40];
  char str3[40];
  strcpy (str2,str1);//str1 copies to str2
  strcpy (str3,"copy successful");
  printf ("str1: %s\nstr2: %s\nstr3: %s\n",str1,str2,str3);
  return 0;
}

Example 2: strcmp c++

int strcmp ( const char * str1, const char * str2 );

// returning value | indicates
// <0	the first character that does not match has a lower value in ptr1 than in ptr2
// 0	the contents of both strings are equal
// >0	the first character that does not match has a greater value in ptr1 than in ptr2
