ios manipulators nouppercase() function in C++
  • Difficulty Level : Basic
  • Last Updated : 28 Aug, 2019

The nouppercase() method of stream manipulators in C++ is used to clear the showbase format flag for the specified str stream. This flag makes the output operations not to use capital letters instead of lowercase letters.

Syntax:

ios_base& nouppercase (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 nouppercase format flag set.

Example 1:






// C++ code to demonstrate
// the working of nouppercase() function
  
#include <iostream>
#include <sstream>
  
using namespace std;
  
int main()
{
  
    // Initializing the character
    char a, b, c;
  
    // Stream input with leading whitespaces
    istringstream iss("gfg");
  
    // Using nouppercase()
    iss >> a >> b >> c;
  
    cout << "nouppercase flag: "
         << nouppercase
         << a << endl
         << b << endl
         << c << endl;
  
    return 0;
}
Output:
nouppercase flag: g
f
g

Example 2:




// C++ code to demonstrate
// the working of nouppercase() function
  
#include <iostream>
  
using namespace std;
  
int main()
{
  
    // Initializing the int
    int n = 20;
  
    // Using nouppercase()
    cout << "nouppercase flag: "
         << showbase << hex
         << nouppercase
         << n << endl;
  
    return 0;
}
Output:
nouppercase flag: 0x14
