C Program 8: To find area of equilateral, isosceles and scalene triangle.

Aim: to find the area of triangle. Theory: To find area of triangle isn't as simple as it seems to be. There are three kinds of triangles - equilateral (where all sides are equal), isosceles (where two sides are equal) and scalene (where all three sides are of different length). We will write code to ask the user for what kind of data he has and then on basis of that data we would apply the mathematical formulae. Here's the...

What To Expect Here?

I knew I could simply start with posting the C Programs which I need to code myself just to increase my efficiency in C programming. In fact, I have already posted a few on PerCepTion which is my personal blog but I felt it would not be a good idea to clutter my personal blog with C Programs. Many of my readers are already disappointed with that move so I decided to make things right and started this one. So, by now, from...
