Need a loop to repeat as many times as the user entered

Question

I need help with this assignment. **Here is what i need the program to do: - Write a program that prompts a user for a number of iterations. - The program should then loop that many times. - Each loop the program should prompt the user for a number and add it to a running total. - Print the running total when you are done. I cant get the program to loop as many times as the user enters. I know this is a simple fix but i cant seem to figure it out. Am i using the wrong statement for the loop? ``` Scanner guess = new Scanner(System.in); int count =0; int sum=0; int num; System.out.println("Enter a number"); num = guess.nextInt(); for(count =0; count <= num; count++) { sum +=num; System.out.println("Your results are:"+sum); } ```

Accepted Answer

If you are starting at 0, then you'll want to change

```
for(count =0; count <= num; count++)
```

to

```
for(count =0; count < num; count++)
```

because it starts at 0, so that is the first iteration, and 1 is the second, etc.

Also, you need to keep asking the user every time. So you'll want to do something like this in the loop:

```
sum += guess.nextInt();
```

Lastly, you DON'T want to print the sum every time, just at the END. So AFTER the loop, print the sum.

You might have thought that having `sum += num` will ask the user for another number, but num is just the first number that the user entered (it won't change). You need to get the user's input every iteration.
