A variable defined inside a function has local significance only. A variable defined external to a function is global and may be read but not modified by a function, it should be declared global in the function to be modified. Arguments passed to a function may be in arbitrary order when the name of the parameter is specified upon calling the function. These concepts are illustrate the code where the number of occurrences of a letter in a word is counted and returned along with an incremented value of an input variable.
