static

In C the static keyword is used in 2 cases:

• For variables:

  int fun() {
    static int count = 0;
    count++;
    return count;
  }

  Even if function has been executed, the value of a is kept in memory. So, in this example, every time we call this function a is incremented by 1.

• For functions:

  static int function() {
    // ...
  }

  This function is visible only by functions in the same file (translation unit).
