 Call by value and call by reference in C++ programming language Today we are going to talk about functions in C++ programming language. We will cover the concept of call by value and call by reference in C++ program. Before diving deep into this topic we will look at little introduction of functions in C++ program. By now we know that functions are one of the most important aspect of any programming language and the same is true with respect to C++ program. They are very important building block of C++ program. With the help of functions programmers and developers can divide a program into smaller and manageable parts. With in functions there is a concept of call by value and call by reference. Now we will understand and have a look on this important concept regarding functions. In functions we have studied about that how we can call a function in the main() method. In C++ we use arguments and parameters to send and receive data during function call respectively. We use arguments ...

 Functions And Parameters In C++ Programming Language We have studied about functions in our previous blogs, but now we will discuss about parameters and arguments in functions in C++ programming language. We know that functions are reusable blocks of code that executes specific tasks. Now we will look at the use of functions along with the parameters. The first questions should be that what is a parameter ? In simple words we can define paramteres as placeholder variables inside the function round brackets to accept external data inputs. And the main function of parameters is to hold the data passed to the functions, by functions calling. Before going deep into functions remember that functions are one of the most important building blocks in C++ programming. So in simple words we can say that information or data can be passed to functions as a parameter and these parameters act as variables inside the function. Basic syntax of functions with parameters in C++...

 Functions In C++ Programming Language Today we are going to look at the use of functions in C++ programming language. We use functions to repeat or reuse some piece of code in our program. So a function in C++ is a reusable block of code that executes when it is called. Functions are the most important building blocks in C++ or any other programming language. These funtions allow the developers to divide or break a large program into smaller and manageable segments or parts. With the help of these functions we can reuse the same lines of code again and again or multiple times without need to write these lines of code again and again. Each and every function is used to perform some specific task. These functions are  also referred as procedures or subroutines in different programming languages. We use these functions to achieve modularity in our program. Modular programming means breaking program into smaller independent parts (modules) so it is easy to develop, understand, an...

  Nested  Loops In C++ Programming Language We have studied about loops in C++ programming language. There are three looping statements that we worked with so far i.e, while loop, do-while loop, and for loop. We know that we use loops when we want to repeat or iterate some piece of code according to our programming logic and requirement.  Now the first question arises that what is a nested loop. At this point so far we already have knowledge about loops. Nested loops are nothing they are just a loop that is placed or resides completely inside another loop. In simple words it is a loop inside another loop. And remember one important point, the inner loop completes all of its iterations every single time the outer loop runs once. Basic Syntax Of Nested Loops In C++ Programming Language Now we will look at syntax of for loop , while loop , and do-while loop . Below is a syntax of for nested for loop in C++ programming language Below is a syntax for nested ...

 Do-While Loop In C++ Programming Language The do-while loop is an exit-controlled loop. We have studied about loops before in our previous blog posts let us now look at the do-while loop in C++ programming language. An interesting thing about do-while is that this loop executes at-least once no matter if the given condition is true or false at the very first iteration. It means in both the cases if condition is true or false the do-while will run and execute the piece of code. After that the given condition will decide wether the do-while loop will run or not if the condition is false then the do-while loop will terminate and not run for the second iteration and if the condition is still true then the do-while loop will run. Basic Syntax of Do-while Loop in C++ Programming Language Basic Working of Do-While Loop in C++ Programming Language As we know that these looping statements are used to repeat or iterate some piece of code. In do-while loop first we sho...

  While Loop in C++ Programming Language We have discussed about the entry-controlled loop or pre-tested loop previously in our blog posts. These statements or loops are used to repeat a piece of code for a specific number of times as per our program requirement. We have studied about the for loop already. Today in this blog post we are going to study about the while loop in C++ programming language. And we will look at how this while loop actually works and how we can stop it by making some condition false so that the loop might not run infinitely. We use while loop in C++ program when the number of iterations is not known in advance and depends on the condition. When we know exactly that how many times a loop should run then we use the for loop instead of while loop. Basic Syntax Of While Loop in C++ Programming Language Basic Working Of While Loop In C++ Programming Language Now we are going to discuss about the basic working of while loop in C++ programming....
