Question

Q2. Develop an Application in C++ that will Prepare Final Grade sheet of Students with the following Guidelines: (10 Marks) Develop an Application in C++ that will Create Final Grade sheet of Students with the following Guidelines: User will choose number of students he want to store in Arrays ii. First array will store Students ID Second Array will store Four(4) Subjects/Course Marks and Total Marks Based on the Total Marks the Students Grade-Sheet will be prepared. The Final Grade-Sheet will Generate the Report of Students Details (ID, Subjects marks, Total, Grade) General Guidelines User will accept input as Output should be as follows: 1. Number of Students' Grade- Sheet he want to prepare c\Users\Alamgir Documents\Visual Studio 2008\Projects\Assignment Deb.. 2. ID's of Each Student 3. Marks of Four(4) Subjects How Many Students' GradeSheet you want to Prepare:73 (Sub1,Sub2,Sub3,Sub4) Enter Student-ID & Marks of 3 Students Enter ID of Student 1: 10001 Enter Marks of 4 Subject of Student 1: 78 78 88 70 Enter ID of Student 2: 10082 Enter Marks of 4 Subject of Student 2: 80 80 90 86 Enter ID of Student 3: 10003 Enter Marks of 4 Subject of Student 3: 50 30 40 50 Grade Sheet & Marks Distribution of 3 Students are as follows: ID Subi Sub2 Sub Sub4 Total Grade 19901 70 70 80 70 290 C/C+ 19882 88 89 90 86 336 B/B+ 18003 50 30 40 50 170 Fail

1. Less than 200 F.
2. 200-250 D / D +
3. 250-300 C/ C +
   300-350 B / B +
   350-400 A / A +

Answer 1

c++ code:

#include <iostream>
using namespace std;

int main()
{
//variable declaration
int id[10];
int marks[10][4];
int total[10];
string grade[10];
int n;

//get no of student
cout<<"How many student GradeSheet you want to prepare:? ";
cin>>n;

//for n students
cout<<"Enter student-ID & marks of "<<n<<" students";
for(int i=0;i<n;i++)
{
//get student id
cout<<"\nEnter Id of student "<<(i+1)<<": ";
cin>>id[i];

//get 4 sub marks
cout<<"Enter marks of 4 subject of student "<<(i+1)<<": ";
for(int j=0;j<4;j++){
cin>>marks[i][j];
}
}
  
//calculate the total
for(int i=0;i<n;i++)
{
total[i]=0;
for(int j=0;j<4;j++){
total[i]+=marks[i][j];
}
}
//calculate the grade
for(int i=0;i<n;i++)
{
//total less than 200, grade fail
if(total[i]<200)
grade[i]="Fail";
  
//total 200-250 D / D +
if(total[i]>=200 && total[i]<250)
grade[i]="D/D+";
//total 250-300 C/ C +
if(total[i]>=250 && total[i]<300)
grade[i]="C/C+";
  
//total 300-350 B / B +
if(total[i]>=300 && total[i]<350)
grade[i]="B/B+";
  
//total 350-400 A / A +
if(total[i]>=350 && total[i]<400)
grade[i]="A/A+";

}

//grade sheet and marks print
cout << "\nGrade Sheet & Marks Distribution of "<<n<<" Students are as follows:" << endl;
cout<<"*****************************************************";
cout<<"\n\nID\t Sub1 Sub2 Sub3 Sub4 Total Grade ";
cout<<"\n*****************************************************";

//print the student detail on screen
for(int i=0;i<n;i++)
{
cout<<"\n"<<id[i];
for(int j=0;j<4;j++){
cout<<"\t"<<marks[i][j];
}
cout<<"\t"<<total[i]<<"\t"<<grade[i];
cout<<"\n--------------------------------------------------------";
}
cout<<"\n\n";

return 0;
}

output:
