In this blog, you will learn about functions in C programming, including their definition, types, and how to use them to make your code more modular and efficient.
The compiler tracks thenull-stateof every expression in your code at compile time. Thenull-statehas one of two values: not-null: The expression is known to be not-null. maybe-null: The expression might benull. Variable annotations determine thenullabilityof a reference type variable: ...
Multiple inheritance is a type of inheritance in which a class derives from more than one class. As shown in the above diagram, class C is a subclass that has class A and class B as its parent. In a real-life scenario, a child inherits from their father and mother. This can be cons...

There are rules to ignore preprocessor directives in the grammar, but the parse can fail for a number of reasons, e.g., if a #ifdef tries to break a statement across the "then" and "else", using non-ISO extensions, etc. === Someone didn't refactor the noptr-abstract-declarator rule...
if((a<c)||(b<d)) cout<<"Logical OR is true"<<endl; else cout<<"Logical OR is false"<<endl; } Output: a is not zero Logical AND is true Logical OR is true In the above program, we have made use of all the three logical operators in order to evaluate expressions and print ...

type NullToString = A | B | C with override this.ToString() = if this=A then null else "not A" // FS3263: With nullness checking enabled, overrides of .ToString() method must return a non-nullable string. You can handle potential nulls via the built-in string function. Handling null...
Kinds of value types and type constraints Built-in value types C# language specification See also Value typesandreference typesare the two main categories of C# types. A variable of a value type contains an instance of the type. This differs from a variable of a reference type, which contains...
Defining constants using the #define preprocessor directiveIf you don't want to get confused in your own code and you want to understand the purposes of the data used in your program, you should always try to set meaningful names for all constants. For this purpose, the #define preprocessor...
