Inputs and Outputs C++

Inputs and Outputs Using C++

In this blog I will be giving a brief explanation on the diverse ways to carry out inputs and outputs using C++.  There are output functions such as "printf" as well as an output object like "cout" and there are input objects such as "cin" and input functions such as "scanf". The input allows for variable values to be assigned using input from the user using a keyboard and the output allows for information from the code to be displayed onto a screen.

Inputs into the code is normally stored in variables, variables are memory containers used to store values across several types such as Strings which store text, Integers which store whole numbers, Doubles which store decimal numbers with a lot of digits, Floats which store fewer decimal numbers and Longs which store sixty-four-bit integers. The type of the variable is normally declared before the name of the variable.



Outputs

Printf:

Printf is a formatting type of function that is used to print out into the standard output.

cout: 

Cout also prints out into the standard output, Cout means character output, "<<" shows the direction in which the data is moving. So, in this case the data is moving right which means it's going to the output screen and printing out the text in between the quotations. Std is for standard which together with cout means standard output.


Inputs

Cin 

Cin means character input; it is used to collect input value. The character input gets stored into the variable and moves into the console.


Scanf

Scanf is a function used to read variables from the user's input.

  How to Open a C++ Project on VS2022 and Get Started In this blog I will be going through a step by step process on how to open a c++ project on Visual Studio 2022 and print "Hello World". Before you begin you would need  Visual Studio 2022  , Once downloaded and set up you are now ready to begin! Step 1: Select the "Create a new project" box which is located at the right side of the screen at the bottom of the "Get Started" drop down. Step 2: At the top of the screen there should be a search bar, Click the search bar and type "C++" and then you will be given a list of options, Select "Empty Project" and click "Next" at the bottom right of the screen. Step 3: Create a Project Name ( I came up with "CPlusTutorial" but you are able to use any name you wish).  After inputing a name select which location on your PC you will like to store your project and then select "Create" at the bottom right corner of the s

How To Write to File on C++

 How To Read and Write Files in C++ This C++ feature allows users to read and write from files, this feature is available in many coding languages. The file contents are added using an input device such as a keyboard, the user's input is then added into a file via the program. When a user wants the code to read from a file, the file goes through the program again and outputs the file contents. This post will teach users how to create a file, read from a file and append a file specifically text files.  Credits:  https://linuxhint.com/cplusplus_read_write/ There are individual code parameters and declerations to open files, close files, read from files, write files and append files, this post will go over the ways to execute them. These are called File Access Modes, these are arguments that have set parameters for if the file exist or doesnt exist.

How To Use Arrays in C++

 How To Use Arrays in C++ This Blog will go over One-Dimensional Arrays and Two-Dimensional Arrays, Arrays are a collection of elements that are the same data type that are stored in a special variable, each one of the elements that are a part of the collection can be individually referenced or used with the use of an index identifier.  The user is the one to specify the size and contents of an array.  Arrays are almost like lists, for example an array can be used to store a list of names of people attending a course or the amount of rainfall in a week. Below is a visual example of an array: 2D Arrays are basically arrays within arrays, the data is structured in matrices or rows and columns, but the values are still stored linearly within the memory. 2D Arrays are useful for when you want to compartmentalize your data. When specifying array values, it is important to note that arrays start at 0 so if you were to give your array a size of five and assign values to each array index you w
