How can I find the number of elements in an array?

Question

I have an int array and I need to find the number of elements in it. I know it has something to do with sizeof but I\'m not sure how to use it exac

Answer 1

If we don't know the number of elements in the array and when the input is given by the user at the run time. Then we can write the code as

C CODE:

while(scanf("%d",&array[count])==1) { 
  count++;
}

C++ CODE:

while(cin>>a[count]) {
  count++;
}

Now the count will be having the count of number of array elements which are entered.
