Variable In mathematics, a variable is a symbol or letter, such as "x" or "y," that represents a value. In algebraic equations, the value of one variable is often dependent on the value of another. For example, in the equation below,yis the "dependent variable" because its value is ...
In simple terms global variables are variables that are declared or defined outside main() and has scope from the point of definition to the end of the program. I have a few questions on global variables. I am using GCC compiler. #include<stdio.h> int a,b; a=b=1; main() { prin...

In C++, a const variable has internal linkage by default (not like C). So this scenario will lead to linking error: Source 1 : const int global = 255; //wrong way to make a definition of global const variable in C++ Source 2 : extern const int global; //declaration It needs to...

in the program. Declaration of the variable is needed for the compilation time; otherwise, the definition is required at the time of linking the program. In the case of using multiple files, variable declarations are very helpful as the definition is done only once, which will be used while...
Only method names declared in the protected type declaration are visible outside the protected type definition. Nothing declared in the protected type body is visible outside. However, all names declared in the protected type declaration are visible in the corresponding protected type body. This rule...
Theindependent variable and the dependent variableare the two main variables in a science experiment. Below is the definition of an independent variable and a look at how you might use it. Key Takeaways: Independent Variable The independent variable is the factor that you purposely change or cont...
The following example shows the definition of such a function −int func(int, ... ) { ... ... } int main() { func(1, 2, 3); func(1, 2, 3, 4); } It should be noted that the function func() has its last argument as ellipses, i.e. three dotes (...) and the one...
