iomanip setfill() function in C++ with Examples

Last Updated : 22 Jul, 2022

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.

Syntax:

setfill(char c)

Parameters: This method accepts c as a parameter which is the character argument corresponding to which the fill is to be set.

Return Value: This method does not returns anything. It only acts as stream manipulators.

Example 1:

// C++ code to demonstrate 
// the working of setfill() function 
  
#include <iomanip> 
#include <ios> 
#include <iostream> 
  
using namespace std; 
  
int main() 
{ 
  
    // Initializing the integer 
    int num = 50; 
  
    cout << "Before setting the fill char: \n"
         << setw(10); 
    cout << num << endl; 
  
    // Using setfill() 
    cout << "Setting the fill char"
         << " setfill to *: \n"
         << setfill('*') 
         << setw(10); 
    cout << num << endl; 
  
    return 0; 
} 

Output:

Before setting the fill char: 
        50
Setting the fill char setfill to *: 
********50

Example 2:

// C++ code to demonstrate 
// the working of setfill() function 
  
#include <iomanip> 
#include <ios> 
#include <iostream> 
  
using namespace std; 
  
int main() 
{ 
  
    // Initializing the integer 
    int num = 50; 
  
    cout << "Before setting the fill char: \n"
         << setw(10); 
    cout << num << endl; 
  
    cout << "Setting the fill"
         << " char setfill to $: \n"
         << setfill('$') 
         << setw(10); 
    cout << num << endl; 
  
    return 0; 
} 

Output:

Before setting the fill char: 
        50
Setting the fill char setfill to $: 
$$$$$$$$50
