int to string Using boost::lexical_cast

First, include the necessary header file for boost::lexical_cast:

#include <boost/lexical_cast.hpp>

Next, declare an integer variable:

int num = 123;

Then, use boost::lexical_cast to convert the integer to a string:

std::string str = boost::lexical_cast<std::string>(num);

Finally, you can use the string variable as needed.
