• SWAPPING TO NUMBERS WITHOUT TAKING ANY TEMPORARY VARIABLE

  /*We generally swap or interchange to variables by taking a temporary variable.Here is a simple program for swapping to numbers without using any intermediate variable*/

  Language=C

  #include<stdio.h>
  int main()
  {
      int a,b;
  
      printf( "Enter the value of a and b=" );
      scanf( "%d%d",&a,&b );
  
      printf( "a and b before swapping\n" );
      printf( "%d %d\n",a,b );
  
      a = a+b;
      b = a-b;
      a = a-b;
  
      printf( "a and b after swapping\n" );
      printf( "%d %d\n",a,b );
  
      return 0;
  }
