I want to know how to print those values

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
