The const keyword stands for constant. It is a variable qualifier that modifies the behavior of the variable, making a variable "read-only". This means that the variable can be used just as any other variable of its type, but its value cannot be changed. You will get a compiler error if you try to assign […]

volatile is a keyword known as a variable qualifier, it is usually used before the datatype of a variable, to modify the way in which the compiler and subsequent program treats the variable. Declaring a variable volatile is a directive to the compiler. The compiler is software which translates your C/C++ code into the machine […]

The static keyword is used to create variables that are visible to only one function. However unlike local variables that get created and destroyed every time a function is called, static variables persist beyond the function call, preserving their data between function calls. Variables declared as static will only be created and initialized the first […]

Variables in the C programming language, which 86Duino uses, have a property called scope. This is in contrast to early versions of languages such as BASIC where every variable is a global variable. A global variable is one that can be seen by every function in a program. Local variables are only visible to the […]
