Classwork 3a - UMBC-CMSC104/General GitHub Wiki

Name the code you use for this project arithmetic.c.

For this assignment, you're to write a program that prompts the user for a integer number. After that, you're to display the following:

A statement as to whether the number is a positive, negative, or zero. (dependent on review)
The number with 5 added to it. Store this into a variable for later user.
The number divided by 2. This number should be output as a double.
Use the variable you stored for the number + 5 and multiply it by 3.

Example output:

Welcome to classwork 3a.  Please enter a number: 4

The number is positive!
4 + 5 = 9
4 / 2 = 2.00000
9 * 3 = 27

To compile it:

gcc arithmetic.c -o arithmetic

To test it after you've compiled it:

./arithmetic

To submit it:

submit cs104_wilson cw03a arithmetic.c

Notes

Use the >, <, and == operators to determine if the number is positive, negative, or zero.
Use a variable to store the results of each computation to make things easier for yourself!
Please reference the code here (classwork 3) and here (variables live demo).
Try an if statement that looks like this:

Code:

if(<condition>)
{
    ....
}
else if(<condition>)
{
    ....
}
else
{
    ....
}
