Write a cout statement that uses the setw manipulator to display the number variable with a field width of 4. Do not use an endl manipulator in your statement. (Assume the program includes the necessary header file for the setw manipulator.)

Answer 1

Following are the statement in C++ Programming language

cout<<setw(4);// set the width

cout<<number; // print the number with the width of 4

include <iomanip> // header file

#include <ios> // header file

#include <iostream> // header file

using namespace std; // namespace

int main() // main function

{

int number = 60;// variable declaration

cout << "previous width:" << number; // print

cout << " After setting the width"<< setw(4);

cout << number; // display number

return 0;
