Getting started with the OneCompiler's D language compiler is simple and pretty fast. The editor shows sample boilerplate code when you choose language as D and start coding.
D language is a general purpose object oriented programming language similar to C in syntax created by Walter Bright and released in 2001. Dlang is more powerful than C++ as it has gained good features from C++ and also has additional features added.
When ever you want to perform a set of operations based on a condition If-Else is used.
You can also use if-else for nested Ifs and If-Else-If ladder when multiple conditions are to be performed on a single variable.
For loop is used to iterate a set of statements based on a condition.
While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.
Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.
Array is a collection of similar data which is stored in continuous memory addresses. Array values can be fetched using index. Index starts from 0 to size-1.
Function is a sub-routine which contains set of statements. Usually functions are written when multiple calls are required to same set of statements which increases re-usuability and modularity.
