How to Convert an Number to a String in C++

Data type conversion is one of the standard practices among programmers, which can be efficient and fast. There are several applications for the int to string conversion in C++, and this article will discuss all the methods to convert a C++ int into a string.

Implicit and explicit conversions are the two types of conversions that users can apply for the C++ conversion of two data types. Users can use built-in methods to perform explicit type conversion, like other programming languages.

The keyword int stores only integer type data and can store data within -2147483648 to 2147483647, usually of size 4 bytes. Int, short for integer, is one of the primary variable types built into the compiler.

On the other hand, users use string data types to store values in characters, letters, and symbols. These contain a collection of characters within single or double quotations.

Conversion of any integer-type data format to a string allows users to accomplish different string operations on that data. Often, arithmetic operations become a soulless task compared to string operations.

Thus sometimes, users need to convert the int into string data type to perform specific tasks. When users want to save their int-type data into text format data in a file, they need to convert the int to string in C++, and when they try to display an int to the console for visual purposes.

Here are some methods that can help convert an int data type into a string:

The stringstream class in C++ is a derived class of iostream that allows executing several operations on streams based on strings like insertion, extraction, etc. Users can perform parsing in different ways and include the “sstream” header file. This C++ class contains the following methods:
