Question

Write a program that reads students names followed by their test scores. The program should output each students’ name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a struct variable of type studentType, which has four components: studentFName and studentLName of type string, testScore of the int(testScore is between 0 and 100), and grade of type char. Suppose that the class has 20 students. Use an array of 20 components of type studentType. Your program must contain at least the following functions:

a. A function to read the students data into the array.

b. A function to assign the relevant grade to each student.

c. A function to find the highest test score.

d. A function to print the name of the students having the highest test score

Your program must output each students name in the form: last name followed by the comma, followed by a space, followed by the first name; the name must be left justified. Moreover, other than declaring the variables and opening the input and output files, the function main should only be a collection of function calls.

Explanation / Answer

Hi I have written code. Please test it.

#include<iostream>
#include<cstdlib>

using namespace std;

struct studentType{
   string studentFName ;
   string studentLName;
   double testScore;
   char grade;
};

void readData(studentType students[], int size);
double higestScore(studentType students[], int size);
void higestScoreName(studentType students[], int size);
void assignGrade(studentType students[], int size);

int main(){
  
   // declaring Student array of size 20
   studentType students[20];
  
   // assigning id and numbers for each student
   readData(students, 20);
  
   //assigning grade to each student
   assignGrade(students, 20);
  
   //printing is, score and grade of each student
   for(int i=0; i<20; i++){
       cout<<students[i].studentLName<<", "<<students[i].studentFName<<"Score: "
               <<students[i].testScore<<", Grade: "<<students[i].grade<<endl;
   }
  
   return 0;
}

void assignGrade(studentType students[], int size){
  
      
   for(int index=0; index<size; index++){
      
       double score = students[index].testScore;
      
       if(score >= 90){
           students[index].grade = 'A';
       }
       else if(score >= 80){
           students[index].grade = 'B';
       }
       else if(score >= 70){
           students[index].grade = 'C';
       }
       else if(score >= 60){
           students[index].grade = 'D';
       }
       else{
           students[index].grade = 'F';
       }
   }  
}

void readData(studentType students[], int size){
  
   for(int i=0; i<size; i++){
       cout<<"Enter first name, last and score of "<<(i+1)<<" student ";
       cin>>students[i].studentFName;
       cin>>students[i].studentLName;
       cin>>students[i].testScore;
   }
}
double higestScore(studentType students[], int size){
   double max = students[0].testScore;
  
   for(int i=1; i<size; i++){
       if(max < students[i].testScore)
           max = students[i].testScore;
   }
  
   return max;
}
void higestScoreName(studentType students[], int size){
  
   double max = higestScore(students, size);
  
   cout<<" Higest Score: "<<max<<endl;
   cout<<" Name of student with higest score: "<<endl;
  
   for(int i=0; i<size; i++){
       if(students[i].testScore == max)
           cout<<students[i].studentLName<<", "<<students[i].studentFName<<endl;
   }
}
