C++ Tutorials

In order to concatenate or combine two or more strings in C++, you may use different ways. These include:

Using + operator
A predefined library function append()
By using strcat() function

In the previous tutorial, we learned using the for loop in C++ if we know how many times to execute a block of code.
The C++ while loop is used to execute a block of code until a certain condition is true.

The switch case is another decision-making statement that allows you to execute one or a block of statements as a certain condition is true. The switch statement is used with the case statement

In this tutorial, we will learn how to delay the execution of code in C++ programs. The following function are explained with examples below:

Sleep() function
sleep_for()
usleep()

In C++, you may sort the vector by using the sort() function. This is defined in the header file, so you have to include this in your C++ file.

The string find() function in C++ is used to find a substring in the given string.
The find() function belongs to the C++ string class.
We must include in the header section

The float is one of the available data types in C++.This is used to store floating point numbers in variables.It’s a numeric literal – in the exponent or fractional form. For example, 10.5.

How to generate random numbers between 1 to 10 in C++? In this short tutorial, I am going to show how to generate random numbers between 1 to 10 in C++. For our examples, we will use the rand() function. The rand() function: Is a built-in function in C++ Standard Library Defined in the <cstdlib> … Read more

One of the ways to get the length of an array is using the sizeof() operator in C++.

There are other ways that you may use to get the array length:

By using pointers hack
size() function in STL
By using the begin() and end() functions of Standard Library

Defined in the header file. Is used to take user input in single as well as multi-lines. A user can enter single or multiple words string

In this tutorial, I will show you examples of calculating the square by writing your own logic as well as the built-in functions provided in the math library.

“Foreach” loop (also range-based for loop) is a way to iterate through array, vectors or other datasets/range in C++.

In this tutorial, we will show you how to swap numbers in C++ in the following ways:By using swap functionBy using the temporary variableUsing + and 1 Using * and /

The While loop is used to execute a block of code until a specified condition is true. Alternatively, you can say, if the execution of the specified code repeatedly is not fixed then we use a while loop.

Purpose of break statement The break statement is used to exit the for, while, do-while loops, and switch statements. As we iterate through a C++ while or for loop and the break statement is executed, the control moves outside of the loop to the next statement (if written). In case of break statement executes inside … Read more
