How can a get a sum of a loop?

Question

Need the output to look exactly like this:

Enter the upper limit: 500
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 = 511

This is what I have so far what should I do:

int limit, i = 1;
long sum = 0;

//Input
System.out.print("Enter the upper limit:");
limit = input.nextInt();

//Setting up the math

for(int I; i <= limit; i*=2) {
System.out.print(i+"+");

Answer 1

Hi Gary, have you done any of the Java course on here. Lots of things that won't work in your code.

Answer 2

I have not:(

Answer 3

Just with some algorithmic mind you can solve your problem.
This is a simple solution for your problem.
for(int i=1; i<=limit; i*=2){
System.out.println(i + " +");
sum+=i;
}
System.out.println("= " + sum);

Gary Hu I would strongly recommend you start with the course. As great as it is that Ghozzi Nassreddine has provided an excellent solution, you will get limited benefit just jumping in like you have.
