# Write a program to find area of triangle in c language

This first lesson is based on number 2 in the NeHe OpenGL tutorials, which are a popular way of learning 3D graphics for game development. It shows you how to draw a triangle and a square in a web page. More on how it all works belowâ€¦ A quick warning: Either way, once you have the code, load it up in your favourite text editor and take a look.

Before we step into the program, Let see the definitions and formulas behind Perimeter and Area Of a Triangle.

Using those values we will calculate the Perimeter of a triangle, Semi Perimeter of a triangle and then Area of a Triangle. User will enter the three sides of the triangle a, b, c. Thats why we used standard formula Step 4: Please be careful while placing the open and close brackets, it may change the entire calculation if you place it wrong C Program to find Area of a Triangle using functions This program allows the user to enter three sides of the triangle.

We will pass those three values to the function arguments to calculate the area of a triangle. We declared the function with three arguments right after the header files.

## C Program Write a Program to Sum of N Number

Calculating the Perimeter of Triangle by calling the function we declared at the beginning of the main. This function will call the main function and execution of that main function will start here Here we declared the semi perimeter value as s and Area.

After completing the function execution then it will return the Area value.C Program Using Structure to Calculate Marks of 10 Students in Different Subjects ; C Program Enter the Student Marks and Find the Percentage and Grade.

Simple Fortran 77 program []. Multiple data card input. This program has two input checks in the READ statement with the END and ERR parameters, one for a blank card to indicate end-of-data; and the other for zero value along with valid data. Learn why the Common Core is important for your child.

Whether you write your own programs in Fortran77, or merely use code written by others, I strongly urge you to use FTNCHEK syntax checker to find mistakes.
