How can I find out the area of the triangle in C language?

Question

I want to find out the area of the triangle in C programing language. I am learning C language. I am a beginner in C. How can I find out the area of the triangle in  C language?

Answer 1

The area of the triangle is A=hb/2. This is the mathematics formula to find out the area of the triangle. We can convert it to the C programming language.   First of all, understand the formula.

Area of the triangle A = hb/2.

A represents the area of the triangle.

h represents the height of the triangle.   

b denotes the base of the triangle 

Now, convert it to C programming language. 

Create a program to find out the area of the triangle in C language  -

We can use the math header files in the C program. To get the exact area of the triangle in the C program, you need to convert into C programming. 

There are three variables like a,b, h. 

a = Area of the triangle in the C program. 

b= Base of the triangle in the C program. 

h = Height of the triangle in the C program. 

Let's create an example in C language - 

#include <stdio.h>

#include<math.h> 

int main()

{

    float a; 

    float b=4.0; 

    float h=4.0;

    a=h*b/2; 

       printf("Area of triangle= %.2f\n", a);

    return 0;

}

Compile and execute the C program. You will get the area of the triangle as output.

 Area of triangle= 8.00  

 

Answer 2

The mathematics is the base of every programming to execute the code in right way.You are mentioned to find out the area of the triangle.

Let's understand with the steps -

1. Area of the triangle - A=bh/2. 

2. Think about the variable in the formula . You must create the variables in the C programming language. There are three variables in that mathematics formula. 

3. Declare three variables in the C program. We assign the data type with the variable in C language

float a; 

float b; 

float h; 

4. Define the variable value. 

b=4.5; 

h=3.6; 

6. Convert area formula in the C language. 

a=h*h/2; 

7. Print the value of a.

This is the way to find out the area of the triangle in the C programming language.
