Question

Assume you have the following declarations:

enum StudentType {BILL, JANE, MARY};
StudentType oneStudent;

Write a function, GetName, that will accept a string as a parameter and return the appropriate StudentType. Provide a main function demonstrating the GetName function in use.

Answer 1

C++ CODE:

#include <iostream>

using namespace std;

// Here, BILL=0, JANE=1, and MARY=2

enum StudentType {BILL, JANE, MARY};

StudentType oneStudent;

StudentType GetName(string name){

    // To convert name to uppercase

    for(int i = 0; i < name.length(); i++)

        name[i] = toupper(name[i]);

    if(name == "BILL")

        return BILL;

    if(name == "JANE")

        return JANE;

    if(name == "MARY")

        return MARY;

}

int main(){

    oneStudent = GetName("Bill");

    cout << oneStudent << endl;// This will print 0 as BILL=0 in enum declaration

    oneStudent = GetName("Jane");

    cout << oneStudent << endl;// This will print 1 as JANE=1 in enum declaration

    oneStudent = GetName("mary");

    cout << oneStudent << endl;// This will print 2 as MARY=2 in enum declaration

    return 0;

}

OUTPUT:

./main 0 1 2
