C Program For Swapping Of Two Arrays.

This Post Contains A C Program For Swapping Of Two Arrays With Correct Source Code & Output. This Program Is Written, Compiled & Executed At Turbo C/C++3.0 Compiler & Will Help You To Understand The Concept Of 'Arrays' & 'For-loop' From C Language. It Is A Well-Structured Program With Proper Comments Which Provides Step-By-Step Description Of Various Features Of The Language In A Simple & Easy-To-Understand Way.


When It Comes To Arrays, Most Of Us Get Confused & Hence Some Of Us Find Or Thinks That This Particular Concept Is Complicated As Well As Tricky. But The Following Code Will Make It Really Simple For You To Understand.

# Note : You Can Simply Copy-Paste The Following Program Or Code Into Compiler For Direct Result.

  
C Program For Swapping Of Two Arrays.

/* Declaration Of Header Files */
#include<stdio.h>
#include<conio.h>

/* Start Of Main Program */
void main()
{
   /* Declaration Of Variables */
   int a[10], b[10], f, p;
   clrscr();

   /* Asking For The Input From User */
   printf(" \n Enter Dimension : ");
   scanf("%d", &f);
   printf(" \n Enter %d Values For Array A : ", f);
   for ( p = 0; p < f; p++ )
   {
        scanf("%d", &a[p]);
   }

   /* Asking For The Input From User */
   printf(" \n Enter %d Values For Array B : ", f);
   for ( p = 0; p < f; p++ )
   {
     scanf("%d", &b[p]);
   }

   /* Printing The Values Of Array A */
   printf(" \n Values For Array A : ");
   for ( p = 0; p < f; p++ )

   }

   /* Source Code For Swapping Of Two Arrays */
   for ( p = 0; p < f; p++ )
   {
     a[p] = a[p] + b[p];
     b[p] = a[p] - b[p];
     a[p] = a[p] - b[p];
   }

   /* Printing The Output On The Screen/Console */
   printf(" \n After Swapping : \n ");
   printf(" Values For Array A : ");
   for ( p = 0; p < f; p++ )
   {
     printf(" %d \t ", a[p]);
   }
   printf(" Values For Array B : ");
   for ( p = 0; p < f; p++ )
   {
     printf(" %d \t ", b[p]);
   }
  
   getch();
}
/* End Of Main Program */

Output  :

Enter Dimension  :  3

Enter 3 Values For Array A  :  1  2  3

Enter Dimension  :  3

Enter 3 Values For Array B  :  4  5  6

Values Of Array A  :  1  2  3

Values Of Array B  :  4  5  6

After Swapping  :

Values Of Array A  :   4  5  6

Values Of Array B  :   1  2  3
