So,Here I am again. This Time I am sharing the Code so that People don't think I manually sort them ;).Also, I would like to congratulate all the dept guys/gals who have excelled as always and awaiting a cool Final Year ahead.
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <algorithm>
using namespace std;
struct stud
{
double cgpa;
double sgpa;
int roll;
};
struct sorter
{
bool operator () (const struct stud a, const struct stud b)
{
return a.cgpa>b.cgpa;
}
};
int main()
{
vectorvec;
ofstream out("res.txt");
ifstream in("in.txt");
struct stud a;
while(in>> a.roll >> a.sgpa >> a.cgpa)
vec.push_back(a);
sort(vec.begin(),vec.end(),sorter());
out<< "Roll\tSGPA\tCGPA\n" ;
for(int i=0;i<vec.size();i++){
out << vec[i].roll << "\t" << vec[i].sgpa << "\t" << vec[i].cgpa << endl;
}
out.close();
in.close();
return 0;
}
This Requires an Input File of the form :: Roll\tSGPA\tCGPA
and Output has the same Format which can be changed as well.
I would be coming out with more of code snippets.Till then Enjoy Life.
PS:
The Actual Cpp File is available at this Link :: Here
The Output File::

Excel will also work :P , automatically arranges columns
@Tikna::Thanks for enlighting me on that front.BTW this blog is about doing things the smarter way and not the laziest way.
Imagine this : if you want to do this for any other dept like CSE or ME.. then you would have to input the data MANUALLY which sucks ;) and finally get it sorted. Also if you had read the first few lines of this blog which goes along this theme :: it was meant to tell people that I don't do it MANUALLY.
How about using a very small shell script :)
first cut -f1, f2
then merge,
then sort
3-4 commands :)
@Somani
I had a pre-written code for it ;).
Yes you are right.. shell scripts are awesome.I was on Windows at that time at M$ Campus. Installing cygwin or finding how to cut would have been more time consuming than Modifying Few Lines and Compiling the Code.
Everything Said and Done,Doing the work Efficiently and in the best possible way only matters.. :D
