Introduction In this post, we will write a small C++ Hello World program and discuss the general structure of a C++ program. In C++ the executable unit is called a function. We will use Code:: Blocks IDE to create a C++ project. Launch IDE Launch Code:: Blocks IDE. https://www.testingdocs.com/launch-codeblocks-ide-on-windows/ Create a Project. https://www.testingdocs.com/create-new-project-in-codeblocks-ide/ C++ source […]
Introduction In this post, we will discuss C++ Basic input /output statements. The iostream library provides the objects for doing input and output. cout is the output stream object for output and the << operator. cin is the input stream object for doing the input and the operator >> Include In order to use the […]
Introduction In this post, we will discuss conditional execution using the if statement in C++ programs. C++ if statement in its simplest form and has the following syntax as below: if(expression){ // statements to be executed when the expression is true } Flowchart If the expression is true the action is executed, otherwise the […]
Introduction In this post, we will discuss for loop as it is used often in C++ programs. For loop allows you to execute the action for each iteration in the loop. Syntax for(for initialization; for expression ; post expression) { // loop statements } Loop statements can be a single statement or group of statements […]
Introduction In this post, we will discuss the iteration using the while loop statement. Using while statement is a simple way to execute a statement or group statements repeatedly in a C++ program. while( expression) action Flowchart Sample program /************************* * C++ while loop demo *************************/ #include <iostream> using namespace std; int main() […]
Introduction In this post, we will discuss the C++ switch statement and its flow in a simple C++ program. When a switch statement is executed, its expression is evaluated. If the value of the expression equals the case expression the flow is transferred to the action with the matching case expression. Syntax switch(SwitchExpression){ case CaseExpression1: […]
