C Program To Find Area and Perimeter of Triangle

In this article, we are going to write a c program to find area and perimeter of triangle

We will make this program in the following way -:

  • C Program To Find Area and Perimeter of Triangle (Simple Way)
  • C Program To Find Area and Perimeter of Triangle Using Function
  • C Program To Find Area and Perimeter of Triangle Using Pointer

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

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 and Perimeter of Triangle

C Program To Find Area and Perimeter of Triangle

Algorithm

  • Program Start
  • Declare Variables
  • Input values
  • calculate area of triangle
  • print area of triangle
  • input values
  • calculate perimeter of triangle
  • print perimeter of triangle
  • Program End

Program

#include <stdio.h>
void main()
{
  int b, h, aot, x,y,z, perimeter;

  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);

  printf("Enter sides of a triangle\n");
  scanf("%d %d %d", &x, &y, &z);

  perimeter= x+y+z;
  printf("Perimeter of a triangle : %d", perimeter);
}

Output

Enter base and hight of a triangle
3
4
Area of the triangle = 6
Enter sides of a triangle
3
4
5
Perimeter of a triangle : 12

C Program To Find Area and Perimeter 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
  • Calling Function to find perimeter
  • input values
  • calculate perimeter of triangle
  • print perimeter of triangle
  • Program End

Program

#include <stdio.h>
int area(int b, int h)
{   int aot;
    aot = (b*h)/2;
    return (aot);
}
void perimeter()
{
  int x,y,z,perimeter;
  printf("Enter sides of a triangle\n");
  scanf("%d %d %d", &x, &y, &z);

  perimeter = x+y+z;
  printf("Perimeter of a triangle : %d", perimeter);
}
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));
  perimeter();

}

Output

Enter base and hight of a triangle
3
4
Area of the triangle = 6
Enter sides of a triangle
3
4
5
Perimeter of a triangle : 12

C Program To Find Area and Perimeter of Triangle Using Pointer

Program

#include <stdio.h>
int area(int *b, int *h)
{   int aot;
    aot = (*b)*(*h)/2;
    return (aot);
}
void perimeter(int *x, int *y, int *z)
{
  int perimeter;

  perimeter = (*x)+(*y)+(*z);
  printf("Perimeter of a triangle : %d", perimeter);
}
void main()
{
  int b, h,x,y,z;

  printf("Enter base and hight of a triangle\n");
  scanf("%d %d", &b,&h);

  printf("Area of the triangle = %d\n",area(&b,&h));

  printf("Enter sides of a triangle\n");
  scanf("%d %d %d", &x, &y, &z);
  perimeter(&x,&y,&z);

}

Output

Enter base and hight of a triangle
3
7
Area of the triangle = 10
Enter sides of a triangle
2
1
7
Perimeter of a triangle : 10
