• Aim: Write a function Exchange to interchange the values of two variables, say x and y. illustrate the use of this function in a calling function.
• Code:

  //For turbo C++ remove below comments
  #include <stdio.h>
  //#include<conio.h>
  void swap(int *x, int *y){
      int temp;
      temp=*x;
      *x=*y;
      *y=temp;
  }
  void main()
  {
      int a,b;
      //clrscr();
      printf("Enter a : ");
      scanf("%d",&a);
      printf("Enter b : ");
      scanf("%d",&b);
      printf("Before Swapping a=%d and b=%d\n",a,b);
      swap(&a,&b);
      printf("After Swapping a=%d and b=%d ",a,b);
      // getch();
  }
