    These errors would not be here if you listened to what Salem said in post 3. You are being asked to make a program that is hard enough, that you need to use functions to do it. Before you say you don't know what functions are, they are easy to learn: Functions in C and C++ - Cprogramming.com

    Functions are useful because they break your program up into sections you can call whenever you want. Then read Salem's reply again. Suddenly everything makes sense.

    I really do hope you try. So far you have shown a fantastic lack of effort.

    Lightbulb missed 1 bracket

    If you had followed the previous advises you'd have reached the solution a long time ago.
    You have missed only one closing bracket, ignoring other bad practices. You need to close the switch block before ending the loop.
    Try compiling this program...

    Code:
    #include<iostream>
     using namespace std;
    int main()
    {
        float x,y,r;
        const double p=3.14;
        double area;              
        float a,b;
        float d;
        int choes ;
        
        do {
            cout<<"[simple porogram]"<<endl;
            cout<<" ==============="<<endl;
            cout<<"main menu"<<endl;
            cout<<"========="<<endl;
            cout<<" Enter the number (1) to calculate area and vicinity of rectangle . "<<endl;
            cout<<" Enter the number (2) to calculate area and vicinity of circle . "<<endl;
            cout<<" Enter the number (3) to calculate area of triangle . "<<endl;
            cout<<" Enter the number (4) to calculate  vicinity of triangle . "<<endl;
            cout<<" Enter the number (5) to calculate area and vicinity of square . "<<endl;
            cout<<" Enter the number (6) to drow a rectangle ."<<endl;
            cout<<" Enter the number (7) to drow a triangle ."<<endl;
            cout<<" Enter the number (8) to drow diamond."<<endl;
            cout<<" Enter the number (0) to end program."<<endl;//another suggestion to improe the menu.
            cout<<" ===================================="<<endl;
            cout<<" Enter the number :"<<endl;
        
            cin>>choes;
        
            switch (choes)
            {
                case 1:
                    cout<<"enter the length  : ";
                    cin>>x;
                    cout<<"enter the width :";
                    cin>>y;
                    cout<<"the area of rectangle is :"<<x*y<<endl;
                    cout<<"the vicinity of rectangle is :"<<(x+y)*2<<endl;
                    break ;
                case 2:
                    cout<<"enter the radius :"<<endl;
                    cin>>r;
                    area=(r*r)*p;
                    cout<<"the area of circle is :"<<area<<endl;
                    cout<<"the vicinity of circle is :"<<(r*p)*2<<endl;
                    break;

                    break;
                case 4:
                    cout<< "Enter lengths ribs :"<<endl;

                    cout<< "the vicinity of triangle is :"<<a+b+d<<endl;
                    break;

                    cout<<"Enter the length of the rib :   "<<endl;
