How to convert int to string in C++?

Question

Aryan Kumar · Answer

There are a few ways to convert an int to a string in C++. One way is to use the
to_string() method. The to_string() method takes an integer as a parameter and returns a string representation of the integer. For example, the following code converts the integer 10 to a string:
C++
int number = 10;
string stringNumber = to_string(number);
Another way to convert an int to a string is to use the std::stringstream class. The
std::stringstream class can be used to create a string stream that can be used to convert different types of data to strings. For example, the following code converts the integer 10 to a string using the
std::stringstream class:
C++
int number = 10;
std::stringstream ss;
ss andlt;andlt; number;
string stringNumber = ss.str();
Finally, you can also convert an int to a string using the sprintf() function. The
sprintf() function takes a pointer to a string as a parameter and returns the number of characters that were written to the string. For example, the following code converts the integer 10 to a string using the
sprintf() function:
C++
int number = 10;
char stringNumber[10];
sprintf(stringNumber, "%d", number);
Which method you use to convert an int to a string will depend on your specific needs. If you need to convert an int to a string quickly and easily, then the
to_string() method is a good option. If you need to convert an int to a string and you need to preserve the formatting of the integer, then the
std::stringstream class is a good option. And if you need to convert an int to a string and you need to return the number of characters that were written to the string, then the
sprintf() function is a good option.
