In this article Requirements See also New in the C23 standard, thetypeofoperator is a unary operator that returns the type of an expression. It can be used in type declarations, type casts, type checks, and so o
Theis,as, andtypeofoperators can't be overloaded. A user-defined type can't overload the()operator, but can define custom type conversions performed by a cast expression. For more information, seeUser-defined conversion operators. C# language specification ...

typeof is an operator provided by several programming languages to determine the data type of a variable. This is useful when constructing programs that must accept multiple types of data without explicitly specifying the type.The GNU compiler (GCC) extensions for the C programming language provide ...
It should be noted that the final result of expression is converted to type of variable on left side of assignment operator before assigning value to it. Also, conversion of float to int causes truncation of fractional part, conversion of double to float causes rounding of digits and the conve...
Fig 7: Output image of explicit type conversion example In the given example, var1 and var2 are integer variables. When dividing var1 by var2 and storing the result in a float variable called “result,” the decimal values are truncated. However, by using a type cast operator in line 10...
Operator '+' cannot be applied to operands of type 'int' and 'bool'. int c = a + test; Note C and C++ developers, notice that in C#, bool is not convertible to int. The compiler embeds the type information into the executable file as metadata. The common language runtime (CLR) ...
How to Use typeof, Statement Expressions and Block-Scope Label Names By Dmitry Mikhailichenko, June 2007 (Updated by Douglas Walls, June 2016) This article gives an overview of the following C-language extensions (part of the GNU C-implementation) introduced in the Oracle Developer Studio C ...
The NOT operator switches the result of the expression to the other Boolean value. For example, if an expression is true, the NOT operator returns false. To override the order of precedence when two or more logical operators are used in a conditional expression, you can use parentheses....
