String copy program

STRCPY():-

                       String copy function copies the string from source to destination. The strings may not overlap, and the destination string dest must be large enough to receive the copy. Beware of buffer overruns. string copy return a pointer to the destination string dest.
 

syntax:-

     char *strcpy(char *to, const char *from);

 

using strcpy :-

 

#include<stdio.h>

#include<string.h>

main()

{

  char a[]="Google";

  char b[15];

  int i=0;

  strcpy(b,a);

  for(i=0;b[i]!=0;i++)

   {

        printf("%c",b[i]);

   }

}

 

 

With out using Strcpy:-

 

#include<stdio.h>

#include<string.h>

int main()

{

    char str1[12]="Google";

    char str2[20];

    int i=0;

    while(str1[i]!='\0')

      {

        str2[i] = str1[i];

        i++;

      }

    str2[i]='\0';

    printf("copied string=\t%s\n",str2);

}

Out Put:-

 

      copied String = google
