In this article, we are going to **write a c program to find area of Triangle.**

We will make this program in the following way -:

- C Program To Find Area of Triangle (Simple Ways)
- C Program To Find Area of Triangle Using Function
- C Program To Find Area of Triangle Using Pointer

To make this program, we will use the following concept given below.

- Function in C
- Pointer in C

If you do not know about these topics well, then you may not understand this program, so you should know about them in detail from the link given above.

Now without wasting time let’s start programming.

## C Program To Find Area of Triangle (Simple Ways)

### Algorithm

- Program Start
- Declare Variables
- Input values
- calculate area of triangle
- print area of triangle
- Program End

### Program

```
//C Program To Find Area of Triangle given base and height
#include <stdio.h>
void main()
{
int b, h, aot;
printf("Enter base and hight of a triangle\n");
scanf("%d %d", &b,&h);
aot = (b*h)/2;
printf("Area of the triangle = %d\n", aot);
}
```

### Output

```
Enter base and hight of a triangle
30
40
Area of the triangle = 60
```

## C Program To Find Area of Triangle Using Function

### Algorithm

- Program Start
- Declare Variables
- Input values
- Calling Function to find area of triangle
- calculate area of triangle
- print area of triangle
- Program End

### Program

```
#include <stdio.h>
int area(int b, int h)
{ int aot;
aot = (b*h)/2;
return (aot);
}
void main()
{
int b, h;
printf("Enter base and hight of a triangle\n");
scanf("%d %d", &b,&h);
printf("Area of the triangle = %d\n",area(b,h));
}
```

### Output

```
Enter base and hight of a triangle
30
70
Area of the triangle = 1050
```

## C Program To Find Area of Triangle Using Pointer

### Program

```
//C Program To Find Area of Triangle Using Pointer
#include<stdio.h>
int area(int *b, int *h)
{
int aot;
aot = (*b)*(*h)/2;
return (aot);
}
void main()
{
int b, h;
printf("Enter base and hight of a triangle\n");
scanf("%d %d", &b,&h);
printf("Area of the triangle = %d\n",area(&b,&h));
}
```

### Output

```
Enter base and hight of a triangle
10
30
Area of the triangle = 150
```
