itoa Function in C++: Key Applications

The itoa function is a non-standard function in C++, as it is not provided in the standard library. However, some compiler’s standard libraries may include the itoa function.

The itoa function is commonly used to convert integers to strings. Its applications include:

1. Convert integers to strings before printing or writing to a file.
2. Passing integers converted to strings to functions that require string format parameters.
3. Perform string operations on integers after converting them to strings, such as concatenation or comparison operations.

However, since the itoa function is not part of the C++ standard library, it is recommended to use functions from the standard library such as std::to_string or stringstream for integer to string conversion in actual programming.
