I need help with c++ and code blocks

[ILLUMINATY]

Im trying to create a calculator that would calculate the area of a rooms floor and how much would it cost to replace it with a new one.

CurrentlyImtuck on line 7. What in the wourld is an initializer??? I need one before int in line 7.

 

 

1 //Price calculator

2 #include <iostream>

3 using namespace std;

4 int main ()

5

6 {int a,b

7 int S; // area of the rooms floor 

8 double m2 price // price of 1 square meter of tiles

9 double Mamount // amount of money 

10 cout << a * b << endl;

11  cout << "dial in the length of the room"; cin >> a;

12 cout << "dial in the widht of the room"; cin >> b;

13 cout << S = a * b;

14 cout << "the area of the rooms floor": << S << endl;

15 cout << "dial in the price of 1 square meter of tiles":;

16 cin >> m2 price;

17 Psuma = 1,05 * S * << m2 price >>;

18 cout << "the amount of money you need to pay": << Mamount << endl;

19 cout << "Calculation is complete" << endl;

 20 return 0;

}

Line 6 forgot a semi colon. 

 

Edit several lines are missing semi colons.

 

edut edit 

line 8 is either missing a comma or you don’t know that variables cannot have spaces in them.

I would recommend using an IDE to help catch syntax errors, also you can use the code tool in this forum to show code in a more readable way

 

a la:

//Price calculator

#include <iostream>

using namespace std;

int main ()
{
    int a,b
    int S; // area of the rooms floor 
    double m2 price // price of 1 square meter of tiles
    double Mamount // amount of money 
    cout << a * b << endl;
    cout << "dial in the length of the room"; cin >> a;
    cout << "dial in the widht of the room"; cin >> b;
    cout << S = a * b;
    cout << "the area of the rooms floor": << S << endl;
    cout << "dial in the price of 1 square meter of tiles":;
    cin >> m2 price;
    Psuma = 1,05 * S * << m2 price >>;
    cout << "the amount of money you need to pay": << Mamount << endl;
    cout << "Calculation is complete" << endl;
    return 0;
}

(note I didn't change any actual code, those issues @fpo mentioned are still there)

 

also, where is Psuma declared?

//Price calculator

#include <iostream>

using namespace std;

int main ()
{
    int a,b // why integers for a,b and S??
    int S;  
    double m2 price // you have to use an underline "_" to declare that variable, otherwise your compiler throws an error.
    double Mamount  
    cout << a * b << endl; // not sure if you wanted to get this line printed, if so you have to use "".
    cout << "dial in the length of the room"; cin >> a;
    cout << "dial in the widht of the room"; cin >> b;
    cout << S = a * b; // source of error. in this line you want to give out and assign at the same time.
    cout << "the area of the rooms floor": << S << endl;
    cout << "dial in the price of 1 square meter of tiles":; // here you have to use the : inside the ".
    cin >> m2 price;
    Psuma = 1,05 * S * << m2 price >>; //????
    cout << "the amount of money you need to pay": << Mamount << endl;
    cout << "Calculation is complete" << endl;
    return 0;
}

#include <iostream>

using namespace std;

int main()
{
    double a,b,m2_price,Mamount,S; //double, if the room measurements are not whole numbers.
    
    cout << "a * b" << endl; //still not sure, if you realy want/need this line.
    cout << "dail in the length of the room" << endl; cin >> a;
    cout << "dail in the width of the room" << endl; cin >> b;
    S = a*b;
    cout << "the area of the rooms floor: " << S << endl;
    cout << "dail in the price of 1 sqare meter of tiles: " << endl; cin >> m2_price;
    Mamount = 1.05 * S * m2_price;
    cout << "the amount of money you need to pay: " << Mamount << endl;
    cout << "Calculation is complete" << endl;
    
    return 0;
  
}
