Applying random numbers to array

AnEvilVegetable (23)
Hi!

I'm having some trouble with creating an array with random numbers... How am I to write it?

You see where the rand is on row 32 I want one random number in each of the 7 reserved spaces in number[] in the interval of 1-35 using the rand function. How? I don't understand... Please don't direct me to another website because they don't explain. Any if there's anything with the variables it's my fault because i translated them from Swedish to English so I've might have missed one.

Wrong definition
int number[];

It should have a specific size.
Or get rid of '[]'
(By MB...) :) -> sorry Too short.

@Jackson Marie I know that it's a wrong definition. I've not written anything there because I don't know what I'm supposed to write...

I pretty sure you should get rid of '[]'. Fix the remaining syntax errors, and show everybody your output.
But you want to write all generated values into an array right?

That's right. I get 7 values when i remove the [], but can I still modify them?

Apparently, for each of the rows you want to have 7 random numbers from 1-35.

1
2
3
4
5
6
7
 
x = 1;
while(x <= 7)
{
	int number[] = {rand()%35 + 1};
	cout << number[] << " ";
	x++;
}


This code should trigger a compiler error because of line 5. A correct version would be:

1
2
3
4
5
6
7
 
x=0;
while (x < 7)
{
	number[x] = rand()%35 +1;
	cout << number[x] << " ";
	x++;
}

No. This is a temp variable so all data will be destroyed when a program-loop's been finished.
Or use global variable. If you want to access data, you'll need to define an array again.
int array[13][7];

An Ex : For case 13-row, 7-column

int number[7] was defined at line 16 of the whole file

so it's only inaccessible from other functions
theranga (125)
however you're right that it should be a 2D array if you wanted to store the data being outputted
