create folders and files
src

• linal.c

obj

• object files

lib

• vector.c
• vector.h

Makefile

add gitignore to ignore obj files and VS Code specifil files

1. Create vector.c and vector.h files in lib.
2. Implement functions

• void add(int* vector1, int* vector2, int* result);
• void subtract(int* vector1, int* vector2, int* result);
• void dot_product(int* vector1, int* vector2, int* result);
• void cross_product(int* vector1, int* vector2, int* result);

to build and run project use Makefile
all building, running, cleaning commands should be inside Makefile

vector.c is written for 2D vectors.
Change fucntions and make them work for 3D vectors

include all vector.c in linal.c and use all functions of vector.c
