Basics of Array need help !!!
Write a statement that assigns to x the value of the next to last element of the array.
1 #define ARR_SIZE 30
2 main() {
3 int x, arr[ARR_SIZE];
4
5
6 return 0;
7 }
1 #define ARR_SIZE 30
2 main() {
3 int x, arr[ARR_SIZE];
4
5
6 return 0;
7 }
Okay. So, The array is 30 big. It holds 30 elements. But, they are not placed between 1-30, they are placed between 0-29. So if you want the first array, you would do
If you want the last element of the array, you would do
So if you want the value of the next to last element of the array you would do
Then, just do
Now its done.
arr[0];If you want the last element of the array, you would do
arr[29];So if you want the value of the next to last element of the array you would do
arr[?] Post the answer under me if you get it :)Then, just do
x = arr[?];Now its done.
The Council agrees that:
⇒ You almost certainly should be using: -
⇒ You almost certainly should be using: ARR_SIZE
⇒ You need to use ARR_SIZE to access the right array element.
Well sir it says that I must use the ARR_SIZE.
I tried: x= arr[28];
⇒ You almost certainly should be using: -
⇒ You almost certainly should be using: ARR_SIZE

Well sir it says that I must use the ARR_SIZE.
I tried: x= arr[28];

hmm Im not sure if I get this 100%. But I guess you could do
x = arr[ARR_SIZE] - 1;
yes, it worked but it must be x =arr[ARR_SIZE]-2; to next to the last number. Thank you sir.
