Enum type variables are integer values. Addition and subtraction between variables of the same type is allowed without any specific cast but multiplication and division is somewhat more risky and requires an explicit cast. Casts are also required for converting enum variables to and from integer types.
where name is the environment variable name, and value is the value of that variable. The final element of the envp array must be null . In the execl , execlp , execv , and execvp calls, the new process image inherits the current environment variables.
Type inference – C# 3 with implicitly typed local variables var and C# 9 target-typed new expressions new List comprehension – C# 3 LINQ; Tuples – .NET Framework 4.0 but it becomes popular when C# 7.0 introduced a new tuple type with language support [104] Nested functions – C# 7.0 [104] Pattern matching – C# 7.0 [104]
A new pseudo-type dynamic is introduced into the C# type system. It is treated as System.Object, but in addition, any member access (method call, field, property, or indexer access, or a delegate invocation) or application of an operator on a value of such type is permitted without any type checking, and its resolution is postponed until run-time.
In C#, apart from the distinction between value types and reference types, there is also a separate concept called reference variables. [3] A reference variable, once declared and bound, behaves as an alias of the original variable, but it can also be rebounded to another variable by using the reference assignment operator = ref. The variable ...
For example, if a programmer using the C language incorrectly declares as int a variable that will be used to store values greater than 2 15 −1, the program will fail on computers with 16-bit integers. That variable should have been declared as long, which has at least 32 bits on any computer. Programmers may also incorrectly assume that a ...

In C# you have to write three additional instructions: Declare a variable, copy the property value into the variable and copy the variable back to the property after the method call. Enums can be defined inside interfaces; Case statements may contain inequality expressions, like Is >= 3. (in C# this can be mimicked by nested Else and If statements)
