Question

I'm trying to write a program that can ask a user about what type of solid they have and to be able to enter values like radius and length of the shape so the program can calculate the volume of a shape and print the result. I also want to give them a repeating option to input another shape if they want to.

I'm trying to use at least 7 functions that can display an output, the volumes of a rectangular solid, cylinder, sphere, regular tetrahedron, and a right circular cone in this format,

**************

volume=

**************

I also want to be able to print the volume of the largest shape calculated.

Here is my code so far. Please help!

//This program will calculate volumes of multiple types of solids.
//It will calculate certain formulas for solids and volumes.

#include <QCoreApplication>
#include <iostream>
#include <cmath>
using namespace std;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
//SVol = single volume of solid. GVol = Greatest volume of solids.
//Need to repeat option to enter new solid over and over again.
double R, L, W, H, SVol, GVol;
int x, pi;
pi=3.14159265359;
//Type of solid
//Which type of solid
cout << "Which type of solid do you have?" << endl;
cin >> x;

//Information for different solids

//Radius of solid
cout << "Enter Radius" << endl;
cin >> R;

//Length of solid
cout << "Enter Length" << endl;
cin >> L;

//Width of solid
cout << "Enter Width" << endl;
cin >> W;

//Height of solid
cout << "Enter Height" << endl;
cin >> H;
//types of solids
//Rectangle
SVol = L*W*H;

//Cylinder
SVol = pi*pow(R,2)*H;

//Sphere
SVol = (4/3)*pi*pow(R,3);

//Regular Tetrahedron
SVol = (1/(6*sqrt(2)))*pow(L,3);

//Right Circular Cone
SVol = (pi/3) * pow(R, 2) * H;

for ( ; x>=1; x--)
{
int x;
switch(x)
{
if (x = 1) {
// print this message that the solid is...
cout << "Rectangular Solid " << endl;
break;}
}

for ( ; x>=2; x--)
{
if (x = 2) {
//print this message that the solid is...
cout << "Cylinder " << endl;
break;}
}

for ( ; x>=3; x--)
{
if (x = 3) {
//print this message if the solid is...
cout << "Sphere " << endl;
break;}
}

for ( ; x>=4; x--)
{
if (x = 4) {
//print this message if the solid is...
cout << "Regular Tetrahedron " << endl;
break;}
}

for ( ; x>=5; x--)
{
if (x = 5) {
//print this message if the solid is...
cout << "Right Circular Cone " << endl;
break;}
}
cout << "" << x << endl;
}
return 0;
}

Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

#include <iostream>
#include <cmath>
using namespace std;
const double pi=3.14159265359;
int getOption()
{
int x;
cout << "Which type of solid do you have?" << endl;
cin >> x;
return x;
}
double rectangle()
{
double SVol,L,W,H;
//Length of solid
cout << "Enter Length" << endl;
cin >> L;
cout << "Enter Width" << endl;
cin >> W;
cout << "Enter Height" << endl;
cin >> H;

SVol = L*W*H;
return SVol;
}
double cone()
{
double SVol,R,H;
cout << "Enter Radius" << endl;
cin >> R;
cout << "Enter Height" << endl;
cin >> H;
SVol = (pi/3.0) * pow(R, 2.0) * H;
return SVol;

}
double cylinder()
{
double SVol,R,H;
cout << "Enter Radius" << endl;
cin >> R;
cout << "Enter Height" << endl;
cin >> H;
//Cylinder
SVol = pi*pow(R,2.0)*H;
return SVol;

}
double sphere()
{
double SVol,R;
cout << "Enter Radius" << endl;
cin >> R;
SVol = (4.0/3.0)*pi*pow(R,3.0);
return SVol;

}
double tetra()
{
double SVol,L;
//Length of solid
cout << "Enter Length" << endl;
cin >> L;
SVol = (1.0/(6.0*sqrt(2.0)))*pow(L,3.0);
return SVol;

}
void print(double SVol)
{
cout<<"Volume="<<SVol<<endl;
}
void menu()
{
cout<<"Press 1 for rectangle Press 2 for cylinder Press 3 for sphere Press 4 for Tetrahedron Press 5 for cone ";
}
int main()
{
//SVol = single volume of solid. GVol = Greatest volume of solids.
//Need to repeat option to enter new solid over and over again.
double R, L, W, H, SVol, GVol;
int x, pi;

//Type of solid
//Which type of solid

//Information for different solids
char choice='y';
while(choice!='N'&&choice!='n')
{menu();
x=getOption();
switch(x)
{
case 1:
SVol=rectangle();
print(SVol);
break;
case 2:
SVol=cylinder();
print(SVol);
break;

case 3:
SVol=sphere();
print(SVol);
break;

case 4:
SVol=tetra();
print(SVol);
break;

case 5:
SVol=cone();
print(SVol);
break;

default:
cout<<"Invalid input!!"<<endl;
break;

}
cout<<"Continue <y/n>: ";
cin>>choice;
}
return 0;
}

Kindly revert for any queries

Thanks.
