iomanip setbase() function in C++ with Examples Last Updated : 30 May, 2022 Comments Improve Suggest changes Like Article Like Report The setbase() method of iomanip library in C++ is used to set the ios library basefield flag based on the argument specified as the parameter to this method. Syntax: setbase (int base) Parameters: This method accepts base as a parameter which is the integer argument corresponding to which the base is to be set. 10 stands for dec, 16 stands for hex, 8 stands for oct, and any other value stands for 0 (reset). Return Value: This method does not returns anything. It only acts as stream manipulators. Example 1: CPP // C++ code to demonstrate // the working of setbase() function #include <iomanip> #include <ios> #include <iostream> using namespace std; int main() { // Initializing the integer int num = 50; cout << "Before set: \n" << num << endl; // Using setbase() cout << "Setting base to hex" << " using setbase: \n" << setbase(16) << num << endl; return 0; } Output:Before set: 50 Setting base to hex using setbase: 32 Example 2: CPP // C++ code to demonstrate // the working of setbase() function #include <iomanip> #include <ios> #include <iostream> using namespace std; int main() { // Initializing the integer int num = 50; cout << "Before set: \n" << num << endl; // Using setbase() cout << "Setting base to oct" << " using setbase: \n" << setbase(8) << num << endl; return 0; } Output:Before set: 50 Setting base to oct using setbase: 62 Reference: http://www.cplusplus.com/reference/iomanip/setbase/ Comment More infoAdvertise with us Next Article iomanip setbase() function in C++ with Examples G guptayashgupta53 Follow Improve Article Tags : C++ cpp-input-output CPP-Functions Practice Tags : CPP Similar Reads iomanip setfill() function in C++ with Examples The setfill() method of iomanip library in C++ is used to set the ios library fill character based on the character specified as the parameter to this method.
