How to Compile and Run C Programs using GCC

Change to the directory using cd command and navigate the terminal to the directory/folder containing the code you want to run. Let us say that the code you have written is in the file yourfilename.c then,

gcc yourfilename.c
./a.out

and that would start the program on the terminal (just like the black screen of Turbo C, when you run it)

Input/Output in CP Problems (CP is Competetive Programming)

You do not need to worry about the order of input output in these problems and the reason for that is. That generally when you compile, rather than taking the input and output from the default input/output (i.e. keyboard/monitor) they change it to infile/outfile. So what happens is, that even if you print the output of each test case as soon as it runs, it redirects to another file. So it does not mess up.

./a.out < inputfile

that can be used to redirect just the input (from file named "inputfile") rather than the default input, that is keyboard

NOTE: You do not have to add extra statements like "Input Radius: "
