Answer 1

Hey,Hey,Hey!!!

Fasten your seat-belt!!!

I like to explain and express things in such a manner so that everybody can easily understand.

So, let’s dive deep into our problem.

Here is the PseudoCode first:-

Now,Here is the Program code:-

INPUT AND OUTPUT:-

If you need the code ,here it is:-

#include<iostream>

#include <bits/stdc++.h>

using namespace std;

int main(){

    int n,count=0;

    float marks[n];

float average_marks,highest_marks,sum=0;

//Enter number of subjects

// cout<<"Enter number of subjects for which you want to enter marks: ";

cin>>n;

//Enter marks

// cout<<"Enter marks: ";

for(int i=0;i<n;i++){

    cin>>marks[i];

}

//Lets calculate average marks

for(int i=0;i<n;i++){

    sum=sum+marks[i];

}

average_marks=sum/n;

//Lets calculate highest marks

highest_marks=*max_element(marks,marks+n);

//Lets calculate number of marks entered less than the average mark

for(int i=0;i<n;i++){

   if(marks[i] < average_marks){

       count++;

   }

}

cout<<"Average marks is: "<<average_marks<<endl;

cout<<"Highest marks is: "<<highest_marks<<endl;

cout<<"Number of marks entered less than the average marks: "<<count<<endl;

return 0;

}
