How many zeros does 25 factorial have?

25 is the square of 5 and hence it has two 5s in it. In toto, it is equivalent of having six 5s. There are at least 6 even numbers in 25! Hence, the number 25! will have 6 trailing zeroes in it.

How do you count the number of elements in an array?

A number of elements present in the array can be found by calculating the length of the array.


  1. STEP 1: START.
  2. STEP 2: INITIALIZE arr[] = {1, 2, 3, 4, 5}
  3. STEP 3: length= sizeof(arr)/sizeof(arr[0])
  4. STEP 4: PRINT “Number of elements present in given array:” by assigning length.
  5. STEP 5: RETURN 0.
  6. STEP 6: END.

How do you count elements in an array?

count number of bytes with sizeof() function from whole 2d array (in this case 3*20 = 60 bytes) count number of bytes with sizeof() function from first array element strs[0] (in this case 20 bytes) divide whole size with size of one element what will give you number of elements.
