Snippet
import std.stdio; // writefln int main(char[][] args) { // The integer value we will be using to // modify with our nested function. int intValue = 32; // Declaration of the nested function. void multiplyByX(int X) { intValue *= X; } // If we declared a variable after the // function, it would not be able to // access it (e.g. Here). // Call the nested function. multiplyByX(5); // writefln is prefered in D, as printf() // needs to be length delimited or there // will be problems with variable sizes. writefln("Value = ", intValue); // Return successful. return 0; }
