Assignment: Function for storing sequence in array

display0 (8)
Hello!
(Using windows, codeblocks, c++)
I'm trying to make a program to do following!
Make functions for:

//1. Ask user for sequence lenght: 0 <= k <= 300
Validate input

//2. Ask user to enter a sequence of integers
Store the integers in an array

//3. Display sequence by the same order they are entered and max 6 per line

I cannot use any loops in the main.



Can anybody help? :)

use loop outside main?

Yes. But i cannot make it work..
Have not used arrays outside main before.

}   
 
int main()
{	int ar[100] ={0};
    doSomething (ar);
    return 0;

Good look
display0 (8)
what does *ptr mean?
display0 (8)
YES! Something like that!! :) :) thank you!!
i'm not sure how i call the function in the main?
display0 (8)
int getSequenceLength(void);
void storeIntergerInAnArrayFunction(int);

Are these global variables? Or what do these say??

type function(type,..) // function prototype 


int main()
{
     function(someVariable,..); // if you write what you named the funtion in the main function 
                      // we say that you called the function 
}

type function(type,...) // function body or implementation
{
     // some code
}

hope that helped

those are functions check above

Trying to do something like this, but now the main does not work!!

# include <iostream>
using namespace std;

int Sequence_Length(int seq_length)
{
do{
cout << "Enter the sequence length: ";
cin >> seq_length;

if(seq_length >= 0 && seq_length <= 300)
break;
}
while (seq_length >= 0 && seq_length <= 300);

return seq_length;
}

void storesequence(int seq[], int n)
{

cout << "Please enter the sequence of integers: " << endl;
for(int i=0;i<n;i++)
{
cin >> seq[i];
}

for(int i=0;i<n;i++)
{
cout << seq[i] << " ";
}
}


int main()
{
storesequence(Sequence_Length());

return 0;
}
[/output]

read some turorials first instead of gambling http://www.cplusplus.com/doc/tutorial/functions/
