C++ Tutorials

In C++ programming, the value contained in a character variable is ASCII value, not the value itself. For example, consider a char type variable “chr”:chr = ‘A’

In this tutorial, we will show you how to generate multiplication tables in C++. A user is asked to enter the number for which he/she wants to generate the table. Different logics are used to generate the table till 10.

In the first program, we used if..else statement to check if a year is a leap or not. The if statement uses a logical operator OR i.e. “||”. A little explanation is also commented in the code below:

In this short tutorial series of C++, we will show you how to check whether a number entered by the user is even or odd.

In C++, you may use built-in function pow() or write your own logic to get the exponent value. In this tutorial, we will show you different ways of calculating the exponents in C++.

sin() is the built-in function in C++. This function is defined in the library – you have to include this in the header in order to use it. The sin() function takes one argument i.e. a number which is angle and it returns the sine of angle x radians.

In this short tutorial series, we are going to show you how to get the quotient and remainder. As you execute the program, it asks to enter the dividend and divisor values.

You may use different ways for reversing a string in C++. This includes built-in functions that you may use quite easily and you write your own function as well.

The stoi() is the abbreviation of “string to an integer”.
As the full name suggests, stoi() is used to convert string to in C++
stoi() function was introduced in C++ 11

In this tutorial, we will show you ways of splitting a string by comma and space in C++.
There are different you can achieve this task.

– The Find function can be used by including in the header.
– The find function is used to search element in the given range of numbers.
– It takes three parameters – first, last, val

The double is among one of the available data types in C++ like float, int, char etc.
Double data type allows storing bigger floating point numbers (decimal numbers) than the float data type.

The char is a data type in C++
It is used to store single character
The character must be enclosed in single quote e.g. ‘a’, ‘b’, ‘5’

The out in cout refers to output
cout is an object of the ostream class
The header file where this is defined is iostream

OR is a logical operator in C++
The OR is denoted by || (two pipe signs)
The OR is used to evaluate two statements
If both statements are true, it returns 1 i.e. true
