To convert an integer to a string, the argument should be an integer value. argument: This is the value that needs to be converted.To convert an integer to a string, you should specify the data type as a string. data-type: This is the type in which the argument needs to be converted.The syntax of the boost::lexical_cast method is:
#Convert string to int java install
Note: You need to install the Boost libraries first, before executing this method to convert int to string in C++. This function is defined in the library “boost/lexical_cast.hpp” and can perform interconversions of different data types including float, integer, double, and string. The boost::lexical_cast method is another method to convert an integer into a string. The following example illustrates the working of to_string() function in C++:Ĭout header file. 10 is passed to the to_string() method which returns a corresponding string “10”. The variable holding an integer value i.e. This function returns a string object corresponding to the value passed as an argument. This numerical value can be of any data type, including integer, float, double, long double, etc. This function takes a numerical value as a parameter that has to be converted into a string.The to_string() method is included in the header file of the class string, i.e., or.String to_string (unsigned long long num) The syntax of the to_string() function is: This function is used to convert not only the integer but numerical values of any data type into a string. The next method in this list to convert int to string in C++ is by using the to_string() function. The integer 20 is first inserted into the object stream and then extracted to a string variable str. #include // header file for stringstreamĬout >” operators. The following example illustrates the working of stringstream class to convert int to string in C++: You insert the integer 20 into the string object str_s and extracted it to a string variable my_str, which eventually converts the integer 20 into the string “20”. “>”: This operator extracts the value of the stringstream object and stores it in a string variable on the right-hand side.string_object_name: This is the name of the stringstream object that was declared to perform the input/output operations on strings.The syntax to insert and extract data using these operators is:
