C++ Exercises: Formatting the output

C++ Basic: Exercise-10 with Solution

Write a C++ program to format the output.

Sample Solution:

C++ Code :

#include <iostream>
#include <iomanip>    // Needed to do formatted I/O
using namespace std;
 
int main() 
{
    cout << "\n\n Formatting the output :\n";
	cout << "----------------------------\n"; 
   
   double pi = 3.14159265; // this is floating point number
   cout << fixed << setprecision(4); // number is set to display with 4 decimal places
   cout <<" The value of pi : " << pi << endl;
   cout << " The value of pi 4 decimal place of total width 8   : |" << setw(8) << pi << "|" << endl; // setw() sets the total width
   cout << " The value of pi 4 decimal place of total width 10  : |" << setw(10) << pi << "|"<< endl; 
   
   cout << setfill('-'); // setfill() sets to fill the blanks with specified character
   cout << " The value of pi 4 decimal place of total width 8   : |" << setw(8) << pi << "|" << endl; 
   cout << " The value of pi 4 decimal place of total width 10  : |" << setw(10) << pi << "|"<< endl; 
   
   cout << scientific;  // set value in scientific format with exponent
   cout <<" The value of pi in scientific format is : " << pi << endl;
   
   bool done = false; // this is boolean variable
   cout <<" Status in number : " << done << endl;  
   cout << boolalpha;     // set output in alphabet true or false
   cout <<" Status in alphabet : " << done << endl;
   cout << endl;
   return 0;
}

Sample Output:

 Formatting the output :                                               
----------------------------                                           
 The value of pi : 3.1416                                              
 The value of pi 4 decimal place of total width 8   : |  3.1416|       
 The value of pi 4 decimal place of total width 10  : |    3.1416|     
 The value of pi 4 decimal place of total width 8   : |--3.1416|       
 The value of pi 4 decimal place of total width 10  : |----3.1416|     
 The value of pi in scientific format is : 3.1416e+00                  
 Status in mumber : 0                                                  
 Status in alphabet : false
