Question

Determine a scenario that needs a programming solution.

It should include the following:

a.Get data from the keyboard

b.Display data to the screen

This should be wrote in C++. Please include an IPO chart if posseble.

c.Two types of variables

d.At least 1 constant

e.At least 1 arithmetic expression

f.All 3 programming structures: •Sequence structure •Selection structure •Repetition structure

g.At least 2 program-defined functions. The functions can be simple but at least one of the functions must pass an argument by value and by reference

Answer 1

#include <iostream>
using namespace std;
#define PI 3.14 //Constant

// 2 User Define Functions
void range_add(float b,int a);
void perimeter(float *b);

int main()
{
// Two types of varibale
int a;
float b;
// Takes data from Keyboard
cout<<"Enter the integer\n";
cin>>a;
cout<<"Enter the double\n";
cin>>b;
  
// Slection Structure
if( b > a)
range_add(b,a); // call-by-Value
else
perimeter(&b); // call-by-Reference
}

void range_add(float b,int a)   
{
int sum=0,i=0;
// Repetiton Structure to find sum between a and b
for(i=a;i<b;i++)
sum=sum+i;
cout<<"Sum: "<<sum; // Displaying data to Screen
}

void perimeter(float *b)   
{
float p=2*PI*(*b); // Arithmetic Expression
cout<<"Perimeter of the Circle: "<<p;
}
