C++ Program using Manipulators endl and setw


Before starting the program let us know about the use of endl and setw which are called manipulators.

Manipulators:

It is one of the code used in C++ Programming Language to give nice appearance to the output of the code. The effect of these manipulators are only known when we execute the program and look for output.

setw: It is used to give white space in the C++ program like setw(15): which means 15 white spaces.

Syntax for setw:
setw(x)

endl: It is used for terminating the line. For Ex, we use "\n" in C program for new line like wise we use endl for new line in C++ Programming Language.


//Create a model of mark sheet with equal gaps(using setw() function) and line change (using endl).

Source Code

#include<iostream>
using namespace std;
#include<iomanip>
int main()
{
int a,b,c,d,e,total;
float percent;
cout<<"Enter marks of Maths:\n";
cin>>a;
cout<<"Enter marks of DS:\n";
cin>>b;
cout<< "Enter marks of Statistics:\n";
cin>>c;
cout<< "Enter marks of C++:\n";
cin>>d;
cout<< "Enter marks of Microprocessor:\n";
cin>>e;
total=a+b+c+d+e;
percent=total/5;
cout<<endl<<"Subjects"<<setw(12)<<"Marks"<<endl<<"-----------------------------------"<<cout<<"------------------------------"<<cout<<"Total"<<setw(14)<<total<<endl<<"Percent"<<setw(11)<<percent<<"%";
return 0;
}



OUTPUT


Enter marks of Maths:
90
Enter marks of DS:
85
Enter marks of Statistics:
96
Enter marks of C++:
84
Enter marks of Microprocessor:
88

Subjects                Marks
----------------------------------
Maths                     90
DS                           85
Statistics                96
C++                         84
Microprocessor    88
-------------------------------
Total                       443
Percent                   88%
-------------------------------
