In C and C++ programming language there are two parts of a function, Declaration, and Definition.
Function Declarationis the combination of the return type of function, function’s name, and parameters in parenthesis.Function Definitionis the body of the function includes statements and other functions.
In general use, they are defined together as below,
myfunction() // this…
We explained how to declare and define simple functions. They had no return, and in a previous post we explained that main function has an integer return that represents our code is successfully done or not. In C++ programming language, we can easily define many functions…
Functions, also known asProceduresorSub-Programs,Sub-Algorithms,allow to structure programs in segments of code to perform tasks. A Function is a group of statements that has function a name and can be called with parameters to operate…
The Main Functionis the main part of an application coded in C++, it is the designated entry point to a program that is executed in an operating system (on Windows, iOS, Mac-OS, Android, Linux etc.). Every C++ application program has a main function which starts all application statements, and functions. We can create C++ files without the main function and we can use them as a library…
Do you want to learn how to overload a function ? What is Function Overloading ? What does overloaded function means ? How we can use Function Overloading in C++ ? How we can use multiple parameter types in our functions ? Here we go,Function Overloading is used to operate…
1. Memory Address of a Variable
TheRAM(Random Access Memory) is the memory of a computer that can be read and changed in any order, typically used to store working data and machine codes. In some operations, we useROM(Read Only Memory), In our…
Thegotostatement is used to jump to alabelthat provides an unconditional jump from the goto to a labeled statement in the same function. We can also do the same loops as the same in for() while() loops by using goto statement. Instead of goto we mostly use for(), while(), do-while() statements or functions, classes, because they are faster and better than using goto. Rarely…
Our screens are 2D dimensional planes and consists of pixels in X and Y directions. How we display a 3D object in this 2D plane ? 3D objects in our 2D screens are projection of 3D coordinates by using mathematical calculations. In 3D operations, i.e. in 3D graphics, 3D…
In a previous post, we learned that pointers are variables to point address which is also an integer value. That means we can do arithmetic operations on a pointer variable. But do not forget that we operate on the addresses in our RAMs, so we should be careful and we should…
1. Using break in Loops
break statement is used to break code-block in case statements and it is also used to jump out of a loop. In an earlier post, we used break in switch() statements.
For example we can break for() loops, in this loop below we can break in some step before counting all range,
for( int a=0; a<=10; a++)
{
std::cout << a << ",";
