Structured Array

[godsent]

hi
my question goes like this


Write a program that can store stidents' marks into a structured array.the array will store the test marks for 10 students.Each student is required to take 3 tests..

Student No Test1 Test2 Test3
1 50 60 70
2 80 30 70
3 100 50 40
.
.
.
.
.
.

this goes like this for 10 students


the program should be able to ;
(1) Print out all data
(2)Print out data for test 2
(3)Print out the address for array 3
(4)Print out the address for test3

thanks

You haven't asked a question.

You haven't asked a question.

i got to write this program in C++..

the questions are :
1. Print out all the data
2.Print out the data for test 2
3.Print out the address for the array
4.Print out the address for test 3

These are not questions they are statements, and statements 2 and 4 are not complete and make no sense.

Please ask actual questions, we are not going to guess at what you wish to know and we are not going to write your code for you.


I suggest you start by working out what structure (or may be class since it's C++) you will use, and how you will get the data into the program.

Once you are there you can decided how to interface with the user and how you will print the data.

heya thankx
IT WORKED....

helo
i've done this in a one dimensional array..all are working perfectly.... I wana know if i can do it in other way...for eg, using files or 2 dimensional array...

Probably but it's hard to tell without seeing what you have already done

 #include<iostream.h> 
 
 
void main()
{
 
	int stud_id [10]={1,2,3,4,5,6,7,8,9,10}; 
 
 
	int test1[10]={50,80,100,90,70,70,30,60,50,100}; 
 
 
	int test2[10]={60,30,50,80,70,80,20,70,60,100};
 
 
	int test3[10]={70,70,40,90,70,80,50,50,70,90};
 
 
	int * mypointer; 
 
 
	mypointer=stud_id;
 
	mypointer=test1;
 
	mypointer=test2;
 
	mypointer=test3;
 
 
//	cout<<"The address of array student id 1 is "<<&stud_id[0]<<endl;
//	cout<<"The address of array student id 2 is "<<&stud_id[1]<<endl;
 
 
cout<<"Student ID"<<"\t"<<"Test 1"<<"\t"<<"Test 2"<<"\t"<<"Test 3"<<endl;
 
for (int i=0;i<10;i++)
	{
 
		cout<<stud_id[i]<<"\t"<<"\t"<<test1[i]<<"\t"<<test2[i]<<"\t"<<test3[i]<<endl;
 
	}
 
cout<<endl;
cout<<endl;
 
 
cout<<"Student ID for test 2"<<"\t"<<"Test 2"<<endl;
 
for (int t=0;t<10;t++)
	{
 
		cout<<stud_id[t]<<"\t"<<"\t"<<test2[t]<<endl;
 
	}
 
cout<<"The address for test 3 is "<<&test3<<endl;
 
}
 
its as simple as that
..

i want 2 use 2 arrays,one for "test" and one for "student Id"..
please guide me on how to go about

thanks

Obviously the array stud_id doesn't change, you can change the test array to something like

int test[3][10]={
    {50,80,100,90,70,70,30,60,50,100},
    {60,30,50,80,70,80,20,70,60,100},
    {70,70,40,90,70,80,50,50,70,90}
  };

this

	cout<<stud_id[t]<<"\t"<<"\t"<<test2[t]<<endl;

becomes

	cout<<stud_id[t]<<"\t"<<"\t"<<test[1][t]<<endl;

Personally I would be inclined to use a array of structures

typedef struct student {
    int stud_id;
    int test_results[3];
} STUDENT;

STUDENT students[10] = {
    {1, {50, 60, 70}},
    {2, {80, 30, 70}},
    {3, {100,50, 40}},
    {4, {90, 80, 90}},
    {5, {70, 70, 70}},
    {6, {70, 80, 80}},
    {7, {30, 20, 50}},
    {8, {60, 70, 50}},
    {9, {50, 60, 70}},
    {10,{100,100,90}}
  };

you will have to use 2D array for test
