Write a program of Evaluating Expressions in C++

Evaluating two complex Expressions

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

#include <iostream.h> #include <conio.h> int main() { int a = 3; int b = 4; int c = 5; int x, y; cout << " Initial values of the variable:\n"; cout << "a = " << a << " b = " << b << " c = " << c << endl << endl ; x = a * 4 + b / 2 - c * b; // Expressions without side effects cout << " Value of a * 4 + b / 2 - c * b is : " << x << endl; y = --a * (3 + b) / 2 - c++ * b; // Expressions with side effects cout << " Value of --a * (3 + b0 / 2 - c++ * b is : " << y << endl; cout << "\n Values of the variables are now :\n"; cout << "a = " << a << " b = " << b << " c = " << c << endl ; getch (); return 0; }// main

Output:

 Initial values of the variable:
 a = 3    b = 4    c = 5

 Value of   a * 4 + b / 2 - c * b    is  : -6
 Value of --a * (3 + b0 / 2 - c++ * b is : -13

 Values of the variables are now :
 a = 2    b = 4    c = 5
