The noshowbase() method of stream manipulators in C++ is used to clear the showbase format flag for the specified str stream. This flag displays the integers in decimal only. Syntax:

ios_base& noshowbase (ios_base& str)

Parameters: This method accepts str as a parameter which is the stream for which the format flag is to be cleared. Return Value: This method returns the stream str with noshowbase format flag set. Example 1: 

CPP




// C++ code to demonstrate
// the working of noshowbase() function
 
#include <iostream>
 
using namespace std;
 
int main()
{
 
    // Initializing the integer
    int num = 50;
 
    // Using noshowbase()
    cout << "noshowbase flag: "
         << oct
         << noshowbase
         << num << endl;
 
    return 0;
}

Output:

noshowbase flag: 62

Example 2: 

CPP




// C++ code to demonstrate
// the working of noshowbase() function
 
#include <iostream>
 
using namespace std;
 
int main()
{
 
    // Initializing the integer
    int num = 50;
 
    // Using noshowbase()
    cout << "noshowbase flag: "
         << hex
         << noshowbase
         << num << endl;
 
    return 0;
}

Output:

noshowbase flag: 32
