1. Relational Operators and the if Statement

Consider the following code

// This program tests whether or not an initialized value

// is equal to a value input by the user

// PLACE YOUR NAME HERE

#include

using namespace std;

int main( )

{

int num1, // num1 is not initialized

num2 = 5; // num2 has been initialized to 5

cout << "Please enter an integer" << endl;

cin >> num1;

cout << "num1 = " << num1 << " and num2 = " << num2 << endl;

if (num1 = num2)

cout << "Hey, thats a coincidence!" << endl;

if (num1 != num2)

cout << "The values are not the same" << endl;

return 0;

}

Exercise 1: Run the program several times using a different input each time. Does the program do what you expect? Is so, explain what it is doing. If not, locate the error and fix it.

Exercise 2: Modify the program so that the user inputs both values to be tested for equality. Make sure you have a prompt for each input. Test the program with pairs of values that are the same and that are different.

Exercise 3: Modify the program so that when the numbers are the same it prints the following lines:

The values are the same.

Hey thats a coincidence!

Exercise 4: Modify the revised Exercise 3 program by replacing the two if statements with a single if/else statement. Run the program again to test the results.
