    Question 3-dimensional solid program

    Hello,
    I am working on a program where the user enters the 3 dimensions of a solid (any solid) and the program calculates the volume of the figure!
    I have tried it and i have a list of errors, but i can't seem to figure out how to fix them.
    I was hoping that maybe someone here could give me a hand or whatever and help me out here. Below is my code, and below that is my error report!
    Thanks a bunch, i sure hope someone here will be able to help me out!

    Here is my program code:

    Code:
    //Description: This program asks for the 3 dimensions of a solid to calculate the volume of the figure.
    
    #include <iostream>
    #include <cmath>
    #include <string>
    
    int main()
    {
      int menu;
      double cubeside;
      double basel;
      double sqph;
      double radi;
      double cylh;
      double radi2;
      double coneh;
      double radi3;
      double edge;
      double hexh;
      string response;
    
      do
      {
    
    cout << "\fWelcome to the Math Cheater 3000. All I need is for you" << endl;
    cout << "to pick the 3D object and I will calculate the volume of it." << endl;
    cout << "Sounds pretty easy. Can you do it? Just try. The numbers" << endl;
    cout << "corresponds with the 3D figure." << endl;
    
    // Pick a number on the menu
    
      cout << "\n1. Cube \n2. Square Pyramid \n3. Cylinder \n4. Cone \n5. Sphere \n6. Hexagonal Prism" << endl;
      cout << "Pick a number: ";
      cin >> menu;
    
    // Puts up an error that they need to pick a number on the menu and to do it again.
    
      if(menu != 1 && menu != 2 && menu != 3 && menu != 4 && menu != 5 && menu != 6)
      {
       cout << "Pick a number on the menu: ";
       cin >> menu;
      }
    
    // Each menu asks for the important formula points needed for the it to be solved.
    
       if(menu == 1)
       {
        cout << "Pick side length of choosen cube: ";
        cin >> cubeside;
        cout << "The volume of cube is: "<< pow(cubeside,3) << endl;
       }
       if(menu == 2)
       {
        cout << "Pick base length and height." << endl;
        cout << "Base length: ";
        cin >> basel;
        cout << "Height: ";
        cin >> sqph;
        cout << "The volume of square pyramid is: "<< (basel*basel)*(sqph)/3
             << endl;
       }
       if(menu == 3)
       {
        cout << "Pick radius and height of cylinder." << endl;
        cout << "Radius: ";
        cin >> radi;
        cout << "Height: ";
        cin >> cylh;
        cout << "The volume of cylinder is: "<< (3.14 * pow(radi,2)) * cylh << endl;
       }
       if(menu == 4)
       {
        cout << "Pick radius and height of cone." << endl;
        cout << "Radius: ";
        cin >> radi2;
        cout << "Height: ";
        cin >> coneh;
        cout << "The volume of cone is: "<< (3.14 * pow(radi2,2)) * coneh << endl;
       }
       if(menu == 5)
       {
        cout << "Pick radius of sphere." << endl;
        cout << "Radius: ";
        cin >> radi3;
        cout << "The volume of sphere is: "<< (3.14 * pow(radi3,3)) * (4/3)<< endl;
       }
       if(menu == 6)
     {
        cout << "Pick edge length and height." << endl;
        cout << "Edge length: ";
        cin >> edge;
        cout << "Height: ";
        cin >> hexh;
        cout << "The volume of the hexagonal prism is: "<< (.5*(edge * 6))*((edge/2)*(1.732))*(hexh)
             << endl;
       }
    
    // Asks if they want to do it again.
    
        cout << "Again?: ";
        cin >> response;
    
    
      } while (response == "y" || response == "Y");
    
      return 0;
    }
    And my error report:
    Code:
    1project.cpp: In function ‚int main()‚:
    1project.cpp:23: error: ‚string‚ was not declared in this scope
    1project.cpp:23: error: expected `;' before ‚response‚
    1project.cpp:28: error: ‚cout‚ was not declared in this scope
    1project.cpp:28: error: ‚endl‚ was not declared in this scope
    1project.cpp:37: error: ‚cin‚ was not declared in this scope
    1project.cpp:104: error: ‚response‚ was not declared in this scope
    1project.cpp:107: error: ‚response‚ was not declared in this scope
    It would be great if you could let me know if you find it, but i iwll keep on working it out.
    Thank you all for this great website and your help!!!

    These are the same errors as the last time you posted, and they have the same resolution.

    I apologize, I am a bit confused right now.
    Do I have to go somewhere to find the answer or suggestion to my problem, or does someone just post it here if they notice it?
    Thanks for all of your patience with me.

    This response was given to you in your last thread:

    In other words, you want a "using namespace std;" line after your includes.
