Program Listing

swap.c

 #include <stdio.h> 

 

 int swap(int *x, int *y, int t); 

 

 main { 

 int x=0,y=0,t=0; 

 x=20; y=30; t=40; 

 printf(“\n The original value of x: %d”,x); 

 printf(“\n The original value of y: %d”,y); 

 printf(“\n The original value of t: %d”,t); 

 printf(“\nTheir values after calling the function and”); 

 swap(&x,&y,t);

 printf(“\ntheir effect when passed by reference/pointers”); 

 printf(“\n x+1 = %d”,x+1); 

 printf(“\n y+1 = %d”,y+1);

 printf(“\n t+1 = %d”,t+1); 

 getch(); 

 }  

  int swap(int *x, int *y, int t) 

  { 

  t = *x; 

  *x = *y; 

  *y = t;

  }
