    Section Finder

    I have written a program which acts as a contents page for an on-line version of the programming book. When the user types the section number the start page of that section is displayed.

    I'm not sure if I have used an array correctly to store section numbers.

    It should terminate when user enters zero but it doesn't work.

    Code:
    
    
    #include <stdio.h>
    int main ()
    
    
    {
     char section; 
     int section_number [10]= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
     
     while (section!=0)
     
     {
     for (section=1; section<10; section++)
      {
      printf ("\nPlease enter the section number between 1 and 10: ");
      scanf ("%d", &section);
     
       printf ("\nSection '%d' of C programming book starts at page '%d'\n", section, section_number); 
      }
      
      break;
     }
     
     return 0; 
     }

    Thank you.

    I don't think you understand what your loops are doing. Plus, section is an uninitialized variable when you first access it in your while statement.
    Run the code below and and try to understand what it's doing and why. Then rework your code and post it back if you're still having troubles.
    Code:
    #include <stdio.h>
    int main ()
    {
        char section = 1; 
    
        printf("before while\n");
    
        while (section!=0)
        {
            printf("before for\n");
    
            for (section = 1; section < 10; section++)
            {
                printf("in for: section = %d\n", section);
            }
    
            printf("after for\n");
            break;
            printf("after break\n");
        }
    
        printf("after while\n");
    
        return 0; 
    }
    gg

    Sounds like a FAQ problem to me.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    With that attitude, you're probably right...

    Try this:
    Comment your code with information that explains what you are trying to do. Then we might be able to explain why the statements you are using will or will not accomplish your goal.

    This is actually a suggestion to ALL posters looking for help...
