Text Color and Sleep in Dev C++
A simple program to demonstrate how to use text color and sleep in Dev C++. I hope you will find my work useful.
Machine Problem in C++
Create a program that will print your name "Jake" with a delay of 1 second.
Color should be in alternate. (blue,red,green and yellow) using Dev C++.
blue - 1
red - 4
green - 2
yellow - 6
