Thread: 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

thank you very much do you know any book website with exercices where i can train myself ?

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.
