Hi my friends,
i have a hard homework. And i have short limited time.
i tried to solve it but after 4 hours i mixed everything in my mind. Can u help me ? need a sloution with basic C++
Question is ;

You will write a program to maintain student information in a classroom. The program will be menu driven and it will perform insert, delete, print students operations on classroom. The class may have up to 40 students. There are 3 quizzes, 1 midterm and 1 final during term. Each student is identified by a four digit student number and a name(20char) surname(20char).
When your program is started it should print the following to the screen:
1. Insert student
2. Display class
3. Remove student
4. Generate Report
5. Exit
ıf the user types in 1, the program should ask user to enter one student information.
If the user types 2, the program should display the List of students with id name and surname (ordered by student id).
İf the user types 3, the program should ask the user to enter student number which will be removed from the classroom. If the student number is not found the program should display message indicating that the user is not found.
When menu item 4 is selected the program will generate and print the following report.
Student id Name Surname quiz1 quiz2 quiz3 mt1 Final Numeric Score Grade
1354 45 78 50 60 70 61.12 D
4569 70 88 65 90 47 .
7842 35 45 90 55 60 .
. . . . . . . .
. . . . . . . .
High Score 70 80 90 90 70
Low Score 35 45 50 55 47
Average 65.5 80 88.4 55.7 60
Numeric Score=%20 quiz+%30 mt1+%50Final
Grade will be based on following table:
90-100 A
80-89 B
70-79 C
60-69 D
< 60 F
Hint: develop your program by utilizing functions.

i have to bring this homework on 17 oct at 17:00
thanks

This is not a program, you need to come here with a program and have people giving you ideas and pointing to you what you missed your what you need in to your program. I suggest you look at your TXT book and learn float and int, modulus, if / else functions, string, char, etc. Learn how to declare different "type" variables in one program, the operators, operands. Also need "setprecision". You will need a combination of these to create a program that integrate all these figures. That way you will know where to improve or what to do about your program. It won't help if you ask someone to do it for you.

Good luck.

at this point i tried everything. i'm asking bc short time left .. just hours. i think i can learn it by looking to solution. i wrote the menu showing and asking enrty for user part. but need help on functions.

[ahmet33]

#include<stdio.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>

void insert_sts();
void display_class();
void remove_std();
void generate_report();
void main()
{
int selection;
printf("*** Welcome to program ***");
printf("\n\n 1. Insert Student");
printf("\n 2. Display Class");
printf("\n 3. Remove Student");
printf("\n 4. Generate Report");
printf("\n 5. Exit");
printf("\nPlease make a selection : ");
scanf("%d",selection);
if(selection==1)
insert_sts();
if(selection==2)
display_class();
if(selection==3)
remove_std();
if(selection==4)
generate_report();
if(selection==5)
exit(0);
getche();
}
void insert_sts()
{
char name[20],surname[20],stdno[10],quiz1[10],quiz2[10],quiz3[10],grade[10];
printf("\nEnter student name = ");
scanf("%s",name);
printf("\nEnter student surname = ");
scanf("%s",surname);
printf("\nEnter student number = ");
scanf("%s",stdno);
printf("\nEnter result of quiz 1 = ");
scanf("%s",quiz1);
printf("\nEnter result of quiz 2 = ");
scanf("%s",quiz2);
printf("\nEnter result of quiz 3 = ");
printf("%s",quiz3);
getche();
}

warning C4996: 'scanf': This function or variable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

Check that warning.

I would suggest using a class. That way your methods or functions could access the same information.
