Input Problem

[opawix]

Hello ma'am/sir
any help for the codes of input to be align.heres my code:

#include<iostream>
using namespace std;
int main()
{
float pre, mid, semi, final, total;
cout << "Prelim: "<<setw(20)<< "Midterm: "<<setw(20)<< "Semifinal: "<<setw(20)<< "Final: "<<setw(20)<< "Final grade: \n";
cin>>pre>>mid>>semi>>final>>total;
total = (pre+mid+semi+final)/4;
system("pause");
return 0;
}

expected execution:

Prelim: Midterm: Semifinal: Final: Final grade:
1.3 1.2 1.5 1.2 1.3

any help, or just hints. Thanks.

Ye' never state what ye' problems is, but i'll guess it has something to do with float precision. there are a couple o' ways to set precision:

cout << setprecision(2);

//  or 

cout.setf(ios::fixed);
cout.setf(ios::showbase);
cout.precision(2);

Sorry for that.
The problem is that i don't get the cin align to the cout above. i want it align. just don't know the padding syntax for cin. :(

i'm lost.

check this out:-
1.3 space 1.2 space 1.5 space 1.2 space 1.3 enter

#include<iostream>
#include <iomanip>
using namespace std;
int main()
{
float pre, mid, semi, final, total;
cout << "Prelim: "<<setw(5)<< "Midterm: "<<setw(5)<< "Semifinal: "<<setw(5)<< "Final: "<<setw(5)<< "Final grade: \n";
cin>>pre>>mid>>semi>>final;
total = (pre+mid+semi+final)/4;
cout<<"total is="<<total;
system("pause");
return 0;
}

ayeshashahid, can't be done, next input will put in the nextline.

You should just ask for each grade individually. Print the test such as "Prelim" and then wait for input and <enter>. This could be the resulting program output:

Prelim:
1.3
Midterm:
1.2
Semifinal:
1.5
Final:
1.2
Final grade:
1.3

Since there is only one cin , there is no next input.

And how does that help him align the output to the header he displayed :icon_rolleyes:

float pre, mid, semi, final, total;
	cout <<setw(20)<<"Prelim: "<<setw(20)<< "Midterm: "<<setw(20)<< "Semifinal: "<<setw(20)<< "Final: "<<setw(20)<< "Final grade: \n";
	cin>>pre>>mid>>semi>>final>>total;
	total = (pre+mid+semi+final)/4;
	cout<<total;
	system("pause");
	return 0;
