spaces

I'm nearly there with everything, I've been working on my program alot, and I've learnt so much from all your help thanks, couldn't have done it without.But still some trouble...

When the user enters a string such as
2,1,25 or like 2 1 25

could I read each number into an array so its like:

array1 = {2, 1, 25};

without the spaces or , having any effect.

Because I then need to do a for loop to convert these to chars or ints.Any direction to where to start would be of great help.

	int iA[3];

	for(int i = 0; i < 3; i++) scanf("%d", &iA[i]);
	for(int j = 0; j < 3; j++) printf("%d ", iA[j]);

For commas, you may just fgets and strtok by comma.

cool thanks,
also,
how do you capture the length of an int array
... if someone enters 2 1 15

cus i want to do the for loop like this:

for (i=0; i<length; i++)

or could i do the above

int iA[3];

	for(int i = 0; i < 3; i++) scanf("%d", &iA[i]);
	for(int j = 0; j < 3; j++) printf("%d ", iA[j]);

using a char array, and use strlen?
though when i tried it myself i can't get it working.

If you don't know how many numbers a user will enter at runtime and you want all the numbers:

* Not perfect, but easy: declare a big aray, say 1000 numbers. You can get the first 1000 numbers, should be more than you need

* Use dynamic memory, eg. realloc() or a linked list, etc.
