Question

Objective: write a program that grades multiple-choice test
¡ Each question counts 1 credit. Display the final score for each student.

Students’ answer

	0	1	2	3	4	5
Student 0	A	B	A	C	C	D
Student 1	d	B	A	B	C	A
Student 2	e	D	d	A	C	B
Student 3	C	B	A	E	D	C
Key to the Questions
	0	1	2	3	4	5
Key	D	B	D	C	C	D

¡ Here is a sample run:

Student 0’s credit is 4

Student 1’s credit is 3

Student 2’s credit is 2

Student 3’s credit is 1

Answer 1

Code in c++:-

#include<bits/stdc++.h>
using namespace std;
struct student{
   char choice[6];
};
int credits(student &students, char b[])
{
   int credit=0;
   for(int i=0;i<6;i++) {
       if(students.choice[i]==b[i]) credit++;
   }
//   cout<<"credit of "<<char(&students)<<"'s credit is "<<credit<<endl;
return credit;
}
void upper(student &students)
{
   for(int i=0;i<6;i++) students.choice[i]=toupper(students.choice[i]);
}
int main()
{
   char a[6];
   strcpy(a,"DBDCCD");
struct   student student0,student1,student2,student3;
   strcpy(   student0.choice, "ABACCD");
   strcpy(   student1.choice, "dBABCA");
   strcpy(   student2.choice, "eDdACB");
   strcpy(   student3.choice, "CBAEDC");
   upper(student0);
   upper(student1);
   upper(student2);
   upper(student3);
   cout<<"Student0"<<"'s credit is "<<credits(student0,a)<<endl;
   cout<<"Student1"<<"'s credit is "<<credits(student1,a)<<endl;
   cout<<"Student2"<<"'s credit is "<<credits(student2,a)<<endl;
   cout<<"Student3"<<"'s credit is "<<credits(student3,a)<<endl;
   return 0;
}

Output is:-

I just used a simple method to get the desired output,

the above problem can be done by using classes too.

if you need any changes in the code or else if you have any preferences in the coding part such as java language or using classes, etc....
