How do you write a program in java to read ten numbers and print sum of ten integers?
Add the numbers into one variable as you read them in. But if you prefer, you can read the numbers into an array and then use a loop to add the numbers together.
How many whole numbers less than 100 are 2-digit numbers?
So, you want to know how many whole numbers there are between 10-99. Easiest way to think of this is to ask yourself, how many pages did you read if you read 10-99 inclusive? At first thought you might say 99-10=89. So, let's look at something easier. How many pages did you read if you read 2-5 INCLUSIVE? The answer is 4, not 3. So, 99-10+1=90. So, there are 90 whole numbers less than 100. Or, 99 minus 1,2,3,4,5,6,7,8,and 9 (the only single digit #'s) = 90, not counting negative numbers.
What Palindrome numbers?
