    Flags in C programming for beginners

    Good day
    I'm studying c programming and came across with the flag concept
    indeed, this concept is still mysterious to me , i tried to google it and understand what it is about, but find almost nothing that can help me to understand (particularly for a beginner like myself)
    Could someone point me where i can tackle and master this concept?
    Many thanks in advance!!

    A flag is simply the concept of setting a variable to indicate that something has happened.

    Code:
    flagVariable = 0;
    
    if (the thing has happened)
        flagVariable = 1;
    
    That variable can be tested to see if the thing has happened, and the program can react accordingly.

    Code:
    if (flagVariable is 1)
        // the thing has happened, act accordingly

    Any decent book will come with practice problems and exercises.

    A search for "c practice problems" yields plenty of hits. There are some on the main site here, as well.
