Thread: Stopping an Array before reaching size limit.

I'm trying to write a program that will allow the user to input up to 1000 numbers in a one dimensional array.

Code:

/*Function that loads the array*
/void loadArray(int a[]){
     int i;
     for (i = 0; i < ASIZE; i++) {
         printf("Enter up to 1000 numbers: ");
         scanf("%i", &a[i]);
         }
     return;
     }

How would I be able to have the user stop the array when they've entered the amount of numbers that they needed to enter. Right now it continues until 1000 numbers have been entered.

Thank you so much!


I found the answer online!

Code:

printf("Enter the number of elements in array\n");
    scanf("%d",&size);
 
    printf("Enter %d integers\n", size);
 
    for ( c = 0 ; c < size ; c++ )
        scanf("%d", &array[c]);

Make sure you either are working in a c99 compatible implementation or one that allows for variable length arrays.

actually - it is not required - you just need to store the number of filled elements.

That's actually smart. I didn't think of that.

If you read Endothes' edit, you would have seen that that is pretty much the solution that he/she stumbled upon after searching online
