Question

Hope this is right forum to post. Microsoft forums are so chaotic...

I Am trying to execute simple C++ program in VS community 19 on Windows 10.

#include <iostream>  
  
int main()  
{  
    int j{ 0 };  
    int x{ 0 };  
      
    std::cout << "enter any number other than 5\n";  
  
    do  {  
        std::cin >> x;  
        switch (j){  
          
              
        case 0:  
            std::cout << "enter any other number than 1\n";  
            break;  
        case 1:  
            std::cout << "enter any other number than 2\n";  
            break;  
        case 3:  
            std::cout << "enter any other number than 3\n";  
            break;  
        case 4:  
            std::cout << "enter any other number than 4\n";  
            break;  
        case 5:  
            std::cout << "enter any other number than 5\n";  
            break;  
        case 6:  
            std::cout << "enter any other number than 6\n";  
            break;  
        case 7:  
            std::cout << "enter any other number than 7\n";  
            break;  
        case 8:  
            std::cout << "enter any other number than 8\n";  
            break;  
        case 9:  
            std::cout << "enter any other number than 9\n";  
            break;  
        case 10:  
            std::cout << "enter any other number than 10\n";  
            break;  
        }  
          
          
        j++;  
    } while (x != 5 && j < 10);  
      
    if (x == 5) {  
        std::cout << "you entered 5 you scoundrel";  
    }  
    else  
        std::cout << "you are more patient than I Am!";  
  
    return 0;  
}  

Problem happens on runtime, when I enter number for a third time (case 3:), console hangs and nothing happens. I pressed ctrl+c and it threw some weird error and showed window, that sources are not available for module kernelbase.dll, or something. I tried to load sources, but it didn't help. Now same window isn't showing, but this shows after program execution.

PS: tell me how to rename post title, I don't know how would I even call this error!

Thanks for help.

Answer 1

Add the missing ‘case 2: …’.

If you are less patient, you can also try something like this (without long switch):

do 
{
   std::cin >> x;
   std::cout << "enter any other number than " << ++j << std::endl;
} while( x != 5 && j < 10 );

Answer 2

Your code has some bugs :

why switch (j) instead of switch (x) ?

there is no "case 2", so, as you test j, it does not display a message the 3rd time...

Answer 3

LOL I Am blind xDD

I supposed something was wrong with Windows/VS. As it complained about some sources for module kernelbase.dll and opened some weird window about some symbols missing, or something. This is not a standard behavior, after debugging.

I repaired cases and now it works fine.
