Thread: C programming with codeblocks

So start with the part where you prompt for three variables.

Ask the user what operation he would like the program to perform.
The program should perform one of the following add vectors, find the dot product, find the cross product of axb,adn find the angle between them.
The program should display the value requested by the user, or display an error message if the user enters something wrong.
Must use a loop for at least one of the operations, and your vectors must be stored as arrays. Please if anyone can will you show me how to perform this program.

So you found a professor who expects you to use concepts he hasn't taught in class?

or

Did you not pay attention in class, perhaps due to a lack of corporeal presence?

Just follow each step as its written and solve that sub problem.

Sounds like a job for printf()

to enter the x,y,and z values

hmm, sounds like you are scanf() ing for 3 inputs, X, Y and Z

for two vectors a and b

wow this sounds like an awesome place to use a loop

and store them in array.

Hey I read the future.

Ask the user what operation he would like the program to perform.

more scanf() and maybe a switch statement

The program should perform one of the following add vectors, find the dot product, find the cross product of axb,adn find the angle between them.

Ill leve this up to you.

The program should display the value requested by the user, or display an error message if the user enters something wrong.

default:

Must use a loop for at least one of the operations, and your vectors must be stored as arrays.

again, I read the future.

Please if anyone can will you show me how to perform this program.
