t asks us to make a program (using files) that would let a person enter student deatils as follows:
1 > Add student Details
2 > View a student detail
3 > Edit a student's details
4 > Delete a student record
5 > Display all students' grades
6 > Display all students' marks
7 > Display class average and standard deviation
8 > Save a student detail to a file
9 > Exit
I've decided to try to do this problem, step by step (otherwise I get confused), and so I started out with let's say the user picking option 1, to enter student details. Here is my code thusfar.
___________________________________________________________
#include
#include
#include
#include
using namespace std;
int main ()
{
int user_input_number;
double student_id;
string last_name;
string first_name;
int counter;
int number_of_students;
ofstream student_name("information.dat");
cout "Welcome to course marks maintenance" endl;
cout "Please enter a number corresponding to its function" endl;
cout "1 > Add student Details" endl;
cout "2 > View a student detail" endl;
cout "3 > Edit a student's details" endl;
cout "4 > Delete a student record" endl;
cout "5 > Display all students' grades" endl;
cout "6 > Display all students' marks" endl;
cout "7 > Display class average and standard deviation" endl;
cout "8 > Save a student detail to a file" endl;
cout "9 > Exit" endl;
cin >> user_input_number;
if (user_input_number == 1)
{
cout "You have chosen to add student details" endl;
cout "We require you to input 15 details per student" endl;
cout "Please tell us how many students' info you are about to enter" endl;
cin >> number_of_students;
cout "You are kindly requested to enter every student's name" endl;
if (student_name.is_open())
{
for (counter=0; counter=number_of_students; counter++)
{
cout "Enter student last name ==>";
getline (cin, last_name);
student_name last_name endl;
cout "Enter student first name ==>";
getline (cin, first_name);
student_name first_name endl;
}
}
student_name.close();
}
system ("pause");
return 0;
}
__________________________________________________________
Simply put, this program was supposed to work like this: if I entered "1", it would ask me to enter student details, and I wrote code till where I could enter student first and last names. I run the program and it does work, but I have a runtime error. I'll show you a sample output of what I got.
_______________________________________________________
when it enters the place where i key in student names (I chose 2 students), if gives this as output
Enter student last name ==> Enter student first name ==>
Enter student last name ==> (i can give input here)
Enter student first name ==> (i can give input here)
Enter student last name ==> (i can give input here)
Enter student first name ==> (i can give input here)
I wanted to ask, why does it initially repeat this line without any prompt of input?
"Enter student last name ==> Enter student first name ==>"
How can I fix it? What would also be a good efficient way for me to finish the rest of my program? Should I use files or should I use arrays and loops instead? Any tips? Sample program? Ofcourse I don't expect you to write it all for me, I just need a 'kick start'
just send it to my email tnx :[email protected]
