python convert string to integer using base

PYTHON CONVERT STRING TO INTEGER USING BASE INSTALL

The following example illustrates the working of boost::lexical_cast to convert int to string in C++:Ĭout << 'The string representation of the integer num is :' << str << ' ' It passes the integer 50 as an argument to the lexical_cast operator, which converts this integer into the corresponding string “50”. 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:

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++: 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: Operator “>” operators can convert int to string in C++.Operator “>”: The “>” operator in the stringstream class is used to read or extract formatted data from a stream object.It includes the following basic methods in the stringstream class: The stringstream class is included in the “sstream” header file. The stringstream class allows input/output operations on streams based on strings. In this section, you will look into all these three methods in detail. There are three different ways in which you can perform conversion of an int to string in C++.

In this article, you will explore how you can convert an integer into a string in C++. In the above example, the first method that uses a string operation to print the current date is more convenient than the second method which uses an arithmetic operation. Today's date is: 31/05/21 Using Arithmetic Operation:Ĭout << 'Today's date is: 31/05/' << formattedYear Output: Using String Operation:Ĭout << 'Today's date is: 31/05/' << year.substr(2) Output: For instance, consider the following example to print the current date. Sometimes arithmetic operations become a tedious task compared to string operations.

Most of the programming languages provide inbuilt methods to perform explicit type conversion.Ĭonverting data from an integer format to a string allows you to perform various string operations on the data. You can do the conversion of data types in two ways: Implicit type conversion (done by the compiler) and Explicit type conversion (done manually). There are several cases where you need to convert a variable of one data type to another. Data type conversion is a common process that is widely used in programming.
