Question

hello please i need help ASAP QUICKLY

Write down a complete C++ program that will use the following functions related with a triangle;
a) a function that will let the user to input the and to return the sizes of the three sides, let say a, b, c.
b) a function that will calculate and return the area of the triangle; Area=(1/2)(a+b+c)
c) a function that will print the sizes of the triangle and its area on the screen.

Then use these functions in a logical order in a main program.

Answer 1

Solution:

Code:

#include<iostream>

using namespace std;

//Function definitions
int * get_sides();
float calculate_area(int a,int b,int c);
void Print_details(int a,int b,int c,float area);

int main()
{
        int a,b,c,*side;
        //Function call to get 3 sides from user and storing it in a,b,c
        side = get_sides();
        a=*side;
        b=*(side+1);
        c=*(side+2);
        //Function call to calculate area and store it in area
        float area=calculate_area(a,b,c);
        //Function call to print the details.
        Print_details(a,b,c,area);
        
}

int * get_sides()
{
        int a,b,c;
        cin>>a>>b>>c;
        //Static array
        static int side[3];
        side[0]=a;
        side[1]=b;
        side[2]=c;
        //will return the address of the static array side
        return side;
}

float calculate_area(int a,int b,int c)
{
        float area=(float)(a+b+c)/2;
        return area;
}

void Print_details(int a,int b,int c,float area)
{
        cout<<"side a: "<<a<<endl;
        cout<<"side b: "<<b<<endl;
        cout<<"side c: "<<c<<endl;
        cout<<"Area  : "<<area<<endl;
}

Output:
