To be honest i dont know

Anyway i can give you some examples of what is on the test:

1. Suppose thast you are using a programming language that provides the following data types: integer, real, boolean, character and string. For each data value describe below, give a variable name, and its type, for holding the described data.

EXAMPLE:

a) Data: The name of the town where you were born
Vabiable name: town of birth
Variable type: string

Question
Data: The number of students enrolled in a class
Variable name: ____________________________
Variable type: ____________________________

There are three types of question like that on the test.

Variable name: students (or what ever else you want)
Varaible type: Long, Word, Int, or others depending on lanugage

Next is:

Give procedures or function headers for the following problems:

EXAMPLE:
Given: the co-ordinates (x1, y1) and (x2, y2) of two diagonal corner
points of a rectangle
To compute: the height and width of the rectangle
The procedure or function header:

PROCEDURE Height_And_Width (
input parameters x1, y1, x2, y2 : real;
output parameters ht, width : real
);

Question
Given: 2 integers x and y
To compute: the sum of the 2 numbers
The procure or function header:

And this is what i have to find out and study for

There are 2 types of this question

Sum_of_numbers( input parmeters: number1, number1 : real; output parmeter sum : real

Last is:

Write a complete program, in a programming language of your choice, that prompts the user to enter two real numbers. The program should then output the smaller number. Program output should include appropriate user friendly headings.

And here is were i write the program.
---------------------------------------------------------------------------------------

Ok well that is what the test has on it from what i have been told. Unfortuantly i dont have a class i can take were i am now and main campus is about and hour and thirty mins away and i dont want to drive that far just for one class.

If anyone can point me in the right direction i would greatly appreciate it.

Thanks

If you can't answer questions like this, I really encourage you to just take the class. By just learning enough to pass the test, you may fall behind even more in the long run.

I couldn't agree more. Sounds like it would behoove you to actually take a class or 2 on programming. Besides, you're a Frosh.. there's no rush.
