Write a Program in C That Treating Character Arrays as Strings

// Treating character arrays as strings.

#include <stdio.h>

#define SIZE 20

// function main begins program execution

int main( void )

{

   char string1[ SIZE ]; // reserves 20 characters

   char string2[] = "string literal"; // reserves 15 characters

   size_t i; // counter

   // read string from user into array string1

   printf( "%s", "Enter a string (no longer than 19 characters): " );

   scanf( "%19s", string1 ); // input no more than 19 characters

   // output strings

   printf( "string1 is: %s\nstring2 is: %s\n"                  

           "string1 with spaces between characters is:\n",     

           string1, string2 );                                    

   // output characters until null character is reached  

   for ( i = 0; i < SIZE && string1[ i ] != '\0'; ++i ) {

      printf( "%c ", string1[ i ] );                     

   } // end for                                          

   puts( "" );

} // end main
