C Programming: strcpy Function Explained with Example

strcpy is a standard library function in C programming language used to copy a string from one location to another. The function takes two arguments: the destination string and the source string. It copies the characters from the source string to the destination string until it reaches the null character '\0'.

Syntax:

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

Example:

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

int main () {
   char source[] = 'Hello World!';
   char destination[20];

   strcpy(destination, source);

   printf('Source string: %s\n', source);
   printf('Destination string: %s\n', destination);

   return 0;
}

Output:

Source string: Hello World!
Destination string: Hello World!
