CIS 122: Assignment #1 Solution

Problem:

1.(20 points) What output will the following code fragments produce? Provide the answers exactly as the output.

num = 10;
x = 5;
cout << num << " ";
cout << x << " ";
cout << endl;
cout << num << endl;

10 5
10

x = 4;
y = 14;
y = y + x;
x = x + 1;
cout << "x = " << x << '\n';
cout << "y = " << y << '\n';

x = 5
y = 18

1. Add a statement that declares 3 float type variables E, F, and G in a single statment, and initialize them to be 3.32, 4.45, and 6.61.
2. Add a statement to declare an integer named age as an unsigned short. Initialize it to be any number you like, but within the range of unsigned short.
3. Print E, F, and G to the screen such that the output is one line as "E = 3.32, F = 4.45, G = 6.61".
4. Print age to the screen such that the output has the format like "My cat Kitty is 3 years old", if the variable age has a value 3.

Compile and run your program, Correct any errors you have made.

Submit the final program fulfilling all the requirements, and also the output.
