Question

3. Write a program to find the area of a triangle using functions. a. Write a function getData() for user to input the length and the perpendicular height of a triangle. No return statement for this function. b. Write a function trigArea() to calculate the area of a triangle. Return the area to the calling function. c. Write a function displayData() to print the length, height, and the area of a triangle ( use your print string) d. Write the main() function to call getData(), call trigArea() and call displayData().

Answer 1

Answer:

The program in C++ is as follows:

#include<iostream>

using namespace std;

void displayData(int height, int length, double Area){

   printf("Height: %d \n", height);

   printf("Length: %d \n", length);

printf("Area: %.2f \n", Area);

}

double trigArea(int height, int length){

double area = 0.5 * height * length;

   displayData(height,length,area);

   return area;

}

void getData(){

   int h,l;

   cin>>h>>l;

   trigArea(h,l);

}

int main(){

   getData();

   return 0;

}
