Lab $1$: Basic Math Due: $1/27/21$

In this lab you will practice basic math operations in C$++.$ First you will review a program that demonstrates the

use of basic math, then you will write your own C$++$ code that uses basic math.

Example Program

Our example program is about the Dateable Equation. There is a common rule of thumb that you should not

date a person who is younger than seven plus your age divided by two. The Dateable Equation is:

DateableAge $=7+$YourAge $/2$

The lab$\_$example.cpp program calculates the lowest dateable age for a given person's age. Open this program

in a C$++$ IDE $($Integrated Development Environment$).$ Read and understand the code and run the program. Try

changing the given age to see the dateable age for different ages.

Notice that the Dateable Age is always an integer. If your age is an odd number, dividing it by two should result

in a decimal number, so why is the Dateable Age always an integer? The reason is that in C$++$ when you divide

two integers the result is an integer $($the decimal part is truncated$).$ Even if the dateable variable was of type

double, the result of the division would not have a decimal part. In order to have a decimal result from division,

at least one of the numbers involved in the division must be a floating point number $($such as type double$)$ and if

we are saving the result into a variable, the variable must be a floating point type. In this case an integer is the

correct result because we always deal with ages as whole numbers. But in other cases integer division will give

an incorrect result. In another lab we will look at an example where integer division results in an incorrect

result.

Your Program

In this program you will calculate your magic number. Your magic number is calculated by multiplying the

month of your birth by the year of your birth, and taking the modulus of that result and the day of your birth.

The equation is:

MagicNumber $=($month $*$ year$)\%$ day$]$
