How do I execute a .c file?

Question

I have a .c file with a program (obviously written in C):

#include 

int main(int argc, char** argv) {
  printf(\"Hello World\\n\");         


        

Answer 1

You cannot execute an file ".c" from shell. You must compile it first.

For example: We have an file called "file.c"

1. Open a terminal
2. Use gcc for compile the file and make an executable (gcc file.c -o executable)
3. Now you can open the executable file since shell (just go to the folder and execute ./executable
