I want to know how to print the results

Create using code blocks in C code

Define 7 functions. Each function will return a structured variable.

V1= (2,-4, -1)

V2= (1,2,4)

1) Add two vectors

2) Subtract two vectors

3) Multiply a vector by a scalar

4) Negate a vector (invert each value)

5) Take cross product of two vectors

6) Take dot project of two vectors (results in a scalar)

7) Normalize a vector
