Using C Write a program that will define a structure consist

Using C++:

Write a program that will define a structure consisting of the following data members, “fields”:

Name - a string

Student id number – an integer.

Three test scores – positive short integers.

Average –a float

Grade – a character.

Input to the program consists of:

name

id number

three test scores

Requirements:

Use a function to read the name, id number and three test scores, the function will return a structure.

A function to find the average, the function is a void function that takes the entire structure as an argument (by reference) and calculates the average.

A function that takes the average as argument and returns the grade (‘A’,’B’,’C’,’D’, or ’F’) using standard grading.

A function that prints each data member of the structure on a separate line and calls another function that prints the message “You Passed” or “You Failed”.

Display should be like this:

Employee Name :       Roberth Schultz

Id Number :             2345

Tests :

1-78

2-88

3-98

Average :         88.00

Grade :           B         You Passed.

Solution

// C++ code student passed or fail

#include <cstdlib>
#include <iostream>
#include <stdlib.h>
#include <string.h>
#include <algorithm>
#include <fstream>
#include <iomanip>

using namespace std;

// structure
struct student
{
    string name;
   int ID;
   short marks1,marks2,marks3;
   float average;
   char letterGrade;
};
  
// function to read the name, id number and three test scores, the function will return a structure.
student setter()
{
   student e;
   cout<<\"Enter your name : \";
   std::getline(std::cin,e.name);

   cout<<\"Enter your ID : \";
   cin>>e.ID;
  
   cout<<\"Enter 3 test scores : \ \";
   cin>>e.marks1>>e.marks2>>e.marks3;

   return e;
}

// function to find the average, the function is a void function
// that takes the entire structure as an argument (by reference) and calculates the average
void avg(student &e)
{
   e.average=(e.marks1+e.marks2+e.marks3)/3;
}

// function that takes the average as argument and returns the grade (‘A’,’B’,’C’,’D’, or ’F’) using standard grading.
char grade(float average)
{
   if(average>=90)
       return \'A\';
   else if(average>=80)
       return \'B\';
   else if(average>=70)
       return \'C\';
   else if(average>=60)
       return \'D\';
   else
       return \'F\';
}

// function that prints the message “You Passed” or “You Failed”.
void message(float average)
{
   if(average>=60)
       cout<<\" You passed\ \";
   else
       cout<<\" You failed\ \";
}

// function that prints each data member of the structure on a separate line
void print(student e)
{
   cout<<\"\ Name : \";
   cout<<e.name;
   cout<<\"\ ID : \"<<e.ID;
   cout<<\"\ Tests : \";
   cout<<\"\ 1-\"<<e.marks1;
   cout<<\"\ 2-\"<<e.marks2;
   cout<<\"\ 3-\"<<e.marks3;
   cout<<\"\ Average : \"<< e.average;
  
  
   message(e.average);
}
  

int main()
{
   student emp;
   emp = setter();
   avg(emp);
   emp.letterGrade = grade(emp.average);
   print(emp);
   return 0;
}
