Example
The following program in the C programming language defines a function that is named "sales_tax" and has one parameter named "price". The type of price is "double" (i.e. a double-precision floating point number). The function's return type is also a double.
double sales_tax(double price) { return 0.05 * price; }After the function has been defined, it can be invoked as follows:
sales_tax(10.00);In this example, the function has been invoked with the number 10.00. When this happens, 10.00 will be assigned to price, and the function begins calculating its result. The steps for producing the result are specified below enclosed in {} "0.05 * price" indicates that the first thing to do is multiply 0.05 by the value of price, which gives 0.50. "return" means the function will produce the result of "0.05 * price". Therefore, the final result is 0.50.

Famous quotes containing the word example:
“Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
—Marcel Proust (1871–1922)
