C Program to Swap Two Arrays Without Using Temp Variable

C program to swap two arrays without using temp variable; Through this tutorial, we will learn how to swap two arrays without using temp variable in the c program.

Programs to Swap Two Arrays Without Using Temp Variable

To swap two arrays without using temp variable in the c program:

• C Program to Swap Two Arrays Without Using Temp Variable Using For Loop
• C Program to Swap Two Arrays Without Using Temp Variable Using Bitwise Operator

C Program to Swap Two Arrays Without Using Temp Variable Using For Loop

/* C Program to Swap Two Arrays Without Using Temp Variable */
#include<stdio.h>

int main()
{
 int Size, i, a[10], b[10], Temp[10];

 printf("\nPlease Enter the Size of the Array\n");
 scanf("%d", &Size);

 printf("\nPlease Enter the First Array Elements\n");
 for(i = 0; i < Size; i++)
  {
      scanf("%d", &a[i]);
  }

 printf("\nPlease Enter the Second Array Elements\n");
 for(i = 0; i < Size; i ++)
  {
      scanf("%d", &b[i]);
  }

 //Swapping two Arrays
 for(i = 0; i < Size; i++)
  {
    a[i] = a[i] + b[i];
    b[i] = a[i] - b[i];
    a[i] = a[i] - b[i];
  }

 printf("\n a[%d] Array Elements After Swapping \n", Size);
 for(i = 0; i < Size; i ++)
  {
      printf(" %d \t ",a[i]);
  }

printf("\n\n b[%d] Array Elements After Swapping \n", Size);
 for(i = 0; i < Size; i ++)
  {
      printf(" %d \t ",b[i]);
  }

  return 0;
} 

The output of the above c program; as follows:

Please Enter the Size of the Array
5
Please Enter the First Array Elements
1 2 3 4 5
Please Enter the Second Array Elements
6 7 8 9 10
a[5] Array Elements After Swapping
 6 	  7 	  8 	  9 	  10

 b[5] Array Elements After Swapping
 1 	  2 	  3 	  4 	  5

  }

  return 0;
} 

The output of the above c program; as follows:

Please Enter the Size of the Array
5
Please Enter the First Array Elements
1 2 3 5 6
Please Enter the Second Array Elements
10 20 30 40 50
a[5] Array Elements After Swapping
 10 	  20 	  30 	  40 	  50

 b[5] Array Elements After Swapping
 1 	  2 	  3 	  5 	  6
