Problem # 11:

Write a program that inputs the number of students in the class. It then inputs the marks of these students and displays the highest and second highest marks.

Solution:

#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
    int s, count=2, highest, marks, highest_2;
    cout<<"Enter number of students:";
    cin>>s;
    cout<<endl<<"Enter marks:";
    cin>>marks;
    highest_2=highest=marks;
        cout<<endl<<"Enter marks:";
        cin>>marks;
        if(marks>highest_2)
            highest=marks;
        else
            highest_2=marks;
        while(count<s)
        {
            cout<<endl<<"Enter marks:";
            cin>>marks;
            if((marks>highest_2)&&(marks<highest))
            highest_2=marks;
            if(marks>highest_2)
            highest=marks;
            count++;
        }
    cout<<endl<<"Highest marks are:"<<highest;
    cout<<endl<<"2nd highest marks are:"<<highest_2;  
    return 0;
}
