C program to study 'strcpy()' function

In this article, we will see another string function.  Here we will see how to copy two strings using the string function ‘strcpy()’.  This string function is defined in the <string.h> header file

strcpy( ) function copies contents of one string into another string. The syntax for strcpy() function is given below.

char * strcpy ( char * destination, const char * source );

for example, strcpy ( string1, string2) – It copies contents of string2 into string1.

In the below program, the source string “Unclecoder”(input from the user) is copied to the destination string using the strcpy() function. C code for the program is written as below.

#include <stdio.h>
#include <string.h>
#include <conio.h>
void main()
   char source[100], destination[100];
   printf("Enter input string :");
   gets(source);    //read string
   strcpy(destination, source);   //copy operation
   printf("\nSource string:      %s”, source);
   printf("\nDestination string: %s ", destination);  //display result
