In C#, a variable is a name that we give to the memory location and every variable has a specified type that specifies the type of values that can be stored in a variable. All the variables should be declared before they are in use; every variable has a specific type that decides the ...
In these examples, we will discuss another way to declare variables with the method of “extern.” External variables can also be referred to as global variables. The functions can change the values of global variables. The term “extern” is used to declare and define external variables. Thes...
