{


int a, b, sum, difference;


sum = 0;


difference = 0;


cout%26lt;%26lt;"Enter the first number: "%26lt;%26lt;flush;


cin%26gt;%26gt;a;





cout%26lt;%26lt;"\nEnter the second number: "%26lt;%26lt;flush;


cin%26gt;%26gt;b;





sum = a + b;


cout%26lt;%26lt;"\nThe sum of numbers = "%26lt;%26lt;a + b%26lt;%26lt;flush;





cout%26lt;%26lt;"\nSecond number subtracted from first = "%26lt;%26lt;difference%26lt;%26lt;flush;
