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::
Roll SGPA CGPA
