using vector – 20210626l

Goal We want to make a Class Roster program which saves the today’s attendance records of CS101 students. To allow a dynamic roster, we will use vector types for names of students and their attendance records. For the names of students, we use names variable of vector type. vector names; To record the today’s attendance records, we use attedances of vector type. vector attendances; Here we use the character P as the presence, L as the lateness, A as the absence, and E as the excuse. Note: names and attendances are related by the index. For example, if So the name “Henry” and attendance ‘L’ are relate by the index 3. Of course, the index started with 0. Therefore the sizes of names and attendances should be exactly same. Question
In this project, we will make With this main function, cout<<"Attendance Roster"<>choice;
if(choice==”a”) add(names, attendances); else if(choice==”b”) report(attendances); else if(choice==”c”) clear(names, attendances); }while(choice != “d”);
cout<<"Bye."<& names, vector& attendances) which adds new names and attendance records of students. For a simpilicity, we only type the last name without any space. So we can still use cin.
We assume that a user types A, L, E and P properly. Please, check the following screenshot. count
Make a int count(const vector& attendances, char att) which returns the number of attendance records for att. att will be one of A,L,E,P where For example, cout<& attendances) which returns the report uing above count function. For example, if , the following code will print the these results. The number of absent students is 2. The number of late students is 0. The number of excused students is 2. The number of present students is 1. If names and attendances are empty like vector names; vector attendances; , the following code will print the this result. There is no student. clear Make a void clear(vector& names, vector& attendances) which makes names and attendances empty. To make them empty, you may use clear() member function of the vector class. vector v {1,2};// v={1,2} v.clear(); // now v={} empty and size=0
Ref of clear(): http://www.cplusplus.com/reference/vector/vector/c… For example, if we run the code below, , it will show All of records were cleared. Then the following code will print the this result since they are empty. There is no student.
