Programming in D: The Ultimate Guide for Software Engineers

Operations on All Elements

Explore how to perform operations on every element of arrays and slices in D programming. Understand the use of arithmetic, binary, and unary operators on full arrays and the differences when manipulating slices using the [] syntax. This lesson helps clarify how element-wise operations work and the importance of handling slice assignments properly.

We'll cover the following...

Operations on all elements of an array

The [] characters written after the name of an array refers to all elements of the array. This feature simplifies the program when certain operations need to be applied to all of the elements of the array.

import std.stdio;
void main() {
    double[3] a = [ 10, 20, 30 ];
    double[3] b = [  2,  3,  4 ];
    double[3] result = a[] + b[];
    writeln(result);
}
