If you're a beginner in the C language or want to practice there is some challanges for you to train your C!
You can run C code using gcc.exe file. You can find it by downloading mingw (mingw32\bin\gcc.exe).
Using (I'm recommend to add mingw32\bin to your path for using it in this way):
gcc your_c_code.c
(The output usually is a.exe) You can write one short batch script that compiles and run your code! It'll save your time:
gcc your_c_code.c
a.exe
For example go call this file run.bat and after you create it you can open cmd window in the same location and just type:
run
To compile and run this code!.
