Static Variables in Functions

Snippet

A static local variable retains its value between function calls, initialized only once when the program starts.

snippet.c
c
void track_calls() {
    static int count = 0;
    count++;
    printf("Called %d times\n", count);
}

Breakdown

static int count = 0;

Declares a static variable that persists in memory for the duration of the program.

count++;

Increments the value, which will be remembered for the next time the function is called.
