...are important things in programming. Example: extern int variable; /* declaration */ int variable= 8; /* definition with initialization */
In most programming languages, you do not need to specify the variable's type and initial value in a variable declaration. The type is usually inferred from the assigned value, and the initial value can be set separately if needed.
Most programming languages require that you declare all of the variables that you intend to use in a program. A variable declaration is a statement that typically specifies two things about a variable:* The variable's name* The variable's data typePosted by Special:Contributions***EDIT***This can be found on page 56 in "Programming Logic and Design" by Tony Gladdis
"Cousins" of the compiler are those things related to the compiler, and may or may not be part of the compiler. This includes: preprocessors, assemblers, linkers, and interpreters.
This is when you specify the name and type of the variable.Example:int number;The declaration line can also include an instantiation for that variable.Example:int number = 5;When you declare a variable or an object (particularly in OOP programming) , you set aside a chunk of memory space for the data to reside.
The register keyword tells the compiler to store the variable onto the CPU register if space on the register is available. The reasoning is that register operations are always faster than memory operations and thus if used correctly, it can speed up an algorithm. However, the register keyword is a somewhat antiquated procedure since for quite a long time the optimizer in modern compilers are smart enough to detect when storing a variable on the register will be advantageous and will do so during optimization. There for, suggesting to the compiler to store a variable on the register can only make things slower if used incorrectly.The register keyword tells the compiler to store the variable onto the CPU register if space on the register is available.

Q is a variable, it can stand for different things in different cases.Q is a variable, it can stand for different things in different cases.Q is a variable, it can stand for different things in different cases.Q is a variable, it can stand for different things in different cases.
the dependent variable are the things that stay the same
gcc is a c compiler among many other things. It can also be used to compile code in other languages. gcc is a fairly advanced compiler and is used to compile Linux along with most other free(as in free speech) software.
the things you change
both stated the same things
the experimental variable is like the independent variable, which is the only thing you can change in a science experiment, and the dependent variables are the things that stay the same.
