How to prevent a function executes after being executed

Hi,
Is there anyway to stop function c executes again after it is being executed by function a.

Code (text):

var a = function() {

   c(1);

}

var b = function() {

   c(2);

}

var c = function(i) {

   var d = 3 + i;

   console.log(d);

}

a();

b();

Thank you,
