How To Change Int To String C++

C++ int to string

At that place are three ways of converting an integer into a string:

By using stringstream class
By using to_string() method
By using heave.lexical cast

Conversion of an integer into a cord by using stringstream course.

The stringstream form is a stream grade defined in the header file. It is a stream class used to perform the input-output operations on string-based streams.

The following are the operators used to insert or extract the data:

Operator >>: It extracts the data from the stream.
Operator <<: It inserts the data into the stream.

Let's understand the concept of operators through an example.

In the below statement, the << insertion operator inserts the 100 into the stream.
stream1 << 100;
In the below statement, the >> extraction operator extracts the data out of the stream and stores it in 'i' variable.
stream1 >> i;

Let's sympathize through an instance.

Output

In the in a higher place instance, we created the k variable, and want to convert the value of grand into a cord value. We have used the stringstream class, which is used to convert the k integer value into a string value. We tin also accomplish in vice versa, i.e., conversion of string into an integer value is too possible through the use of stringstream class merely.

Permit's empathize the concept of conversion of string into number through an example.

Output

Conversion of an integer into a cord by using to_string() method.

The to_string() method accepts a single integer and converts the integer value or other data type value into a string.

Let's understand through an instance:

Output

Conversion of an integer into a cord by using a heave.lexical cast.

The boost.lexical cast provides a cast operator, i.due east., heave.lexical_cast which converts the string value into an integer value or other information type value vice versa.

Permit's understand the conversion of integer into cord through an example.
