    Depending on what you're doing, I think you need to reset cnt when the user enters the correct answer for a question. In your current code, cnt is only reset when it reaches 10, which is not the same thing.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    i want to reset it to 1

    after every 10 counts if the percentage is <= 50 it should print the stament and break; else it should reset the cnt to 1,, is my code okay

    Why not run it and see.... testing a program is just as much a part of development as writing the actual code

    Perhaps you should make the loops more readable, perhaps:


    Code:
    ...
    
    if( cnt > 10) 
     {
       cnt = 1;
    
        if( percentage <= 50 )
         {
           printf ("Ask you instructor for extra help\n");
           break;                              
         }
      }
    
    ++cnt; 
    }
    Code:
    if( numeric_limits< byte >::digits != bits_per_byte )
        error( "program requires bits_per_byte-bit bytes" );
    24bbs.cpp
