Views: 20

Following program shows you how to calculate triangle circumference. This program gets triangle sides from user and calculates circumference and prints it using following formula Circumference = side1 + side2 + side3

#include <stdio.h>

int main(void) {
	float triangleSide1;
	float triangleSide2;
	float triangleSide3;

	printf("Enter the side1 of triangle:");
	scanf("%f", &triangleSide1);

	printf("Enter the side2 of triangle:");
	scanf("%f", &triangleSide2);

	printf("Enter the side3 of triangle:");
	scanf("%f", &triangleSide3);

	float circumferenceOfTriangle =
		triangleSide1 + triangleSide2 + triangleSide3;

	printf("Circumference of triangle is: %f ", circumferenceOfTriangle);
}

Output:

Enter the side1 of triangle: 20
Enter the side2 of triangle: 20
Enter the side3 of triangle: 40
Circumference of triangle is: 80.000000
