Question

Get all homework scores for one student, calculate and display the sum of the scores, and also display the word “fail” if the sum is lower than 150. Note: we do not know how many homework scores each student will enter.

Ask the user how many homework scores there are at the beginning. Then, ask for a homework score at a time, for as many times as indicated by the user.

C++

Answer 1

C++ Code:

#include<bits/stdc++.h>
using namespace std;
int main()
{
int n;
//n stores count of homework scores

int score;
//score stores current homework score

int tot_score=0;
//tot_score stores total score of the student(initialised to 0)
  
for(int i=0;i<n;i++)
{
cin>>score;
tot_score+=score;
}

//print total score
cout<<tot_score<<endl;

//print "fail" if total score is less than 150
if(tot_score<150)
cout<<"fail"<<endl;
}
