#include // header file for stringstreamĬout >” operators. The following example illustrates the working of stringstream class to convert int to string in C++: You insert the integer 20 into the string object str_s and extracted it to a string variable my_str, which eventually converts the integer 20 into the string “20”. “>”: This operator extracts the value of the stringstream object and stores it in a string variable on the right-hand side.string_object_name: This is the name of the stringstream object that was declared to perform the input/output operations on strings.The syntax to insert and extract data using these operators is: Operator “>” operators can convert int to string in C++.Operator “>”: The “>” operator in the stringstream class is used to read or extract formatted data from a stream object.It includes the following basic methods in the stringstream class: The stringstream class is included in the “sstream” header file. The stringstream class allows input/output operations on streams based on strings. In this section, you will look into all these three methods in detail. There are three different ways in which you can perform conversion of an int to string in C++. In this article, you will explore how you can convert an integer into a string in C++. In the above example, the first method that uses a string operation to print the current date is more convenient than the second method which uses an arithmetic operation. Today's date is: 31/05/21 Using Arithmetic Operation:Ĭout << "Today's date is: 31/05/" << formattedYear Output:

Using String Operation:Ĭout << "Today's date is: 31/05/" << year.substr(2) Output:

For instance, consider the following example to print the current date. Sometimes arithmetic operations become a tedious task compared to string operations. Most of the programming languages provide inbuilt methods to perform explicit type conversion.Ĭonverting data from an integer format to a string allows you to perform various string operations on the data. You can do the conversion of data types in two ways: Implicit type conversion (done by the compiler) and Explicit type conversion (done manually). There are several cases where you need to convert a variable of one data type to another. Data type conversion is a common process that is widely used in programming.
