context1 is an int since you have assigend an int to it here: int currentField = field; var context1 = currentField; but later you are assigning a bool, f.e here: context1 = currentField % 10 != 0; The !=-operator either returns true or false, so you cannot assign it to...

How do I get my logic in this Java program to make my loop work?
java,if-statement,while-loop,int,logic
Try setting min and min2 to Integer.MAX_VALUE. Practically this should solve your problem because the data type of integers you are working with is int. But theoretically, setting min and min2 to the first input value is the correct solution. EDIT: As a matter of fact, I see that you...
Nested foreach loop in a While loop can make the condition for the while loop go over?

I don't think this code is written all that well, but here's a rough idea. The first while loop: while ((2**p)*x)%1 != 0: ... is figuring out how many places in binary to the right of the decimal point will the result be. To use a familiar analogy let's work...

Use “and” many times in loop in Python [closed]
In spite of the fact that something is short-circuiting (and stops evaluation at the first falsy result), there's a more concise way to write this using all: while all([A1 == 0, A2 == 0, A3 == 0, A4 == 0]): # Work here While all of the values being generated...

Another option is using ref to achieve what you want. Essentially, it allows you to pass a reference to your bool instead of the actual value at the time of evaluation. This allows changes to the value to affect the method it was passed to, even if it is a...

That's because scanf() left the trailing newline in input. I suggest replacing this: ch = getchar(); With: scanf(" %c", &ch); Note the leading space in the format string. It is needed to force scanf() to ignore every whitespace character until a non-whitespace is read. This is generally more robust than...

For Code 1, you're continuing to add on to the count. So during the first iteration, the count becomes 12 (the length of "hello, world" is 12), and then during the second iteration, you never reset the count to 0 so count is continuously added on until it reaches 24,...
