How to choose from the menu to calculate each area for each shape? so far it doe

Question

How to choose from the menu to calculate each area for each shape? so far it does not let me choose other thing that 1 because all the numbers that I enter give me the option one to calculate area for square. I need to make the program ask what choice leaving the menu there and and then ask what it needs to calculate each. It is c++ programming and I have to use do while loop.

#include
#include
using namespace std;
//Declare your variables//
double side, base, height, width, length, radius, Areasq, Arearec, Areatri, Areacir;
const double pi = 3.1416;//Use constant for pi so you do not have to keep plugging the number//
int main() //Create a menu to be able to choose what you want to calculate//
{
   int choice;
   do
   {
       cout << endl
       << "1. Area for a square. "
       << "2. Area for a rectangle. "
       << "3. Area for a triangle. "
       << "4. Area for a circle. "
       << "5. EXIT. "
       << "Enter your choice and press return:";
       cin >> choice;
       {
switch (choice)//It should switch from one option to the other//
Case1:
           cout << " Enter the side value and press ENTER: " << endl;
           cin >> side;
           Areasq = side * side;
           cout << " Area: " << Areasq << "m^2" << endl;
           break;
switch (choice)
Case2:
           cout << " Enter width and length and press ENTER: " << endl;
           cin >> width, length;
           Arearec = width * length;
           cout << " Area = " << Arearec << "m^2" << endl;
           break;
           switch (choice)
Case3:
           cout << "Enter the base and height for the triangle and press ENTER:" << endl;
           cin >> base, height;
           Areatri = (1/2)*(base * height);
           cout << " Area = " << Areatri << "m^2" << endl;
           break;
           switch (choice)
Case4:
           cout << " Enter the radius for calculating the circle area: " << endl;
           cin >> radius;
           Areacir = pi * radius * radius;
           cout << " Area = " << Areacir << " m^2 " << endl;
           break;
       }
   }
   while (choice != 5);
   return (0);
}

Explanation / Answer

Hello, Basically your program is fine except little mistakes.

In switch case statement "case" should be all small letters and there should be a space between case keyword and the value. e.g. case 1

That was it, you are good to go.

Here I am posting full working code with corrected mistakes.

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <algorithm>
using namespace std;
//Declare your variables//
double side, base, height, width, length, radius, Areasq, Arearec, Areatri, Areacir;
const double pi = 3.1416;//Use constant for pi so you do not have to keep plugging the number//
int main() //Create a menu to be able to choose what you want to calculate//
{
int choice;
do
{
cout << endl
<< "1. Area for a square. "
<< "2. Area for a rectangle. "
<< "3. Area for a triangle. "
<< "4. Area for a circle. "
<< "5. EXIT. "
<< "Enter your choice and press return:";
cin >> choice;
{
switch (choice)//It should switch from one option to the other//
case 1:
cout << " Enter the side value and press ENTER: " << endl;
cin >> side;
Areasq = side * side;
cout << " Area: " << Areasq << "m^2" << endl;
break;
switch (choice)
case 2:
cout << " Enter width and length and press ENTER: " << endl;
cin >> width, length;
Arearec = width * length;
cout << " Area = " << Arearec << "m^2" << endl;
break;
switch (choice)
case 3:
cout << "Enter the base and height for the triangle and press ENTER:" << endl;
cin >> base, height;
Areatri = (1/2)*(base * height);
cout << " Area = " << Areatri << "m^2" << endl;
break;
switch (choice)
case 4:
cout << " Enter the radius for calculating the circle area: " << endl;
cin >> radius;
Areacir = pi * radius * radius;
cout << " Area = " << Areacir << " m^2 " << endl;
break;
}
}
while (choice != 5);
return (0);
}
