Question

MUST BE WRITTEN IN C++

All user input values will be entered by the user from prompts in the main program. YOU MAY NOT USE GLOBAL VARIABLES in place of sending and returning data to and from the functions. Create a main program to call these 3 functions (5) first function will be a void function it will called from main and will display your name and the assignment, declare constants and use them inside the function; no variables will be passed in and nothing will be returned. (12) In the main program collect variables to calculate the area of a triangle. Send those variables to the function and then using a return statement pass the calculated area back to the main program. Print the area from the main program. (8) in the main program collect two values from the user. call the third function and send in the two values, you will also need to send in a third value to hold the total. Inside the function calculate the total and then from the main program print the total calculated in the function. Do NOT use a return statement but instead use the by ref option to get the value back to the main program from the function. (10) Create a function to accept an array that contains 12 items. Inside the array calculate the total of the 12 items and the average of the 12 items. Display the total and return the average. Print the average from the main program. (3) Include your name as documentation, print your name to the output window. (5) Use of prototypes at the top, proper indentation, good variables, proper placement of variable will also be included in the grading rubric for this assignment, the function body goes at the bottom of the source code

SOURCE CODE:

#include <iostream>

using namespace std;
void function1();
float TriangleArea(float height,float base);
float SumNumbers(float n1,float n2,float *sum);
float Arraysum(int arr[]);
const string name="Student";
const string Assignment="Assignment-1";
int main()
{
    float height=0,base=0,area=0;
    float n1=0,n2=0,sum=0;
    float average=0;

    function1(); //calling function 1 to display name and assignment
  
    cout <<endl<<"Enter height of the Triangle:" ;
    //reading Triangle height from user
    cin >> height;
    //reading Triangle base from user
    cout <<"Enter base of the Triangle:" ;
    cin >> base;
    //calling TriangleArea function
    area=TriangleArea(height,base);
    //printing area value
    cout << "Area of Triangle is :" << area << endl;
  
    cout <<endl<<"Enter first number:" ;

    int a[12]={1,2,3,4,5,6,7,8,9,10,11,12};
    average=Arraysum(a);
    cout << endl<< "Average of array values is:" << average;
  
    return 0;
}
void function1()
{

    // printing name Assignment name
    cout << "Name: " << name << endl << "Assignment: " << Assignment <<endl ;
}

float TriangleArea(float height,float base)
{
    float area=0;
    //TriangleArea calculation
    area=(0.5)*height*base;
    return area;
}

float SumNumbers(float n1,float n2,float *sum)
{
    *sum=n1+n2;
}
//function to read array of 12 values calculating sum and return average
float Arraysum(int a[])

    int i=0,sum=0;
    float average=0;
    for(i=0;i<12;i++)
    {
        //calculating sum
        sum=sum+a[i];
    }
    cout << "Sum of 12 values :" << sum;
    //calculating average
    average=sum/12.0;
    return average;
}

OUTPUT:

Name: Student Assignment: Assignment-1 Enter height of the Triangle: 5 Enter base of the Triangle: 5 Area of Triangle is :12.5 Enter first number:3 Enter second number: 5 Sum is : 8 Sum of 12 values : 78 Average of array values is: 6.5
