Compile and run interactivly a c/c++ file. Useful for beginners

kdev-run.sh

#! /bin/bash

# You can use this script to compile and run a single file c or cpp program interactively
# the code should be open in a editor, while call this script to execute the code

## I had used this script as an alternative to Turbo++ (which my school had asked me to use)
