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.
