c program to copy a string using pointers

: here we copy string without using strcmp by creating our own function which uses pointers.

#include<stdio.h>
 
void copy_string(char*, char*);
 
main()
{
    char source[100], target[100];
 
    printf("Enter source string\n");
    gets(source);
 
    copy_string(target, source);
 
    printf("Target string is \"%s\"\n", target);
 
    return 0;
}
 
void copy_string(char *target, char *source)
{
   while(*source)
   {
      *target = *source;
      source++;
      target++;
   }
   *target = '\0';
}
