May 14, 2017 check prime number program in c using for loop and while loop Prime number program in c using for loop and while loop - InstanceOfJava This is the java programming blog on 'OOPS Concepts', servlets jsp freshers and 1, 2,3 years expirieance java interview questions on java with explanation for interview examination. I have to to get prime numbers using for loop, I have everything and it runs, but it always return 'is prime' Sample Output: 1201 IS PRIME. 77 IS NOT PRIME. 1213 IS PRIME. 88 IS NOT PRIME. 1217 IS PRIME. 99 IS NOT PRIME. 121 IS NOT PRIME. 1431 IS NOT PRIME. 1223 IS PRIME. 141 IS NOT PRIME. 234 IS NOT PRIME. 436 IS NOT PRIME. 547 IS PRIME. 2456 IS NOT PRIME. 34 IS NOT PRIME. So you need to try candidate divisors in a loop, and you need an inner loop to make sure you cast out any repeated factors (for example, 525 will have the prime factors 3, 5, and 7 but you still want to get rid of that second 5). There are three ways to reverse a number in Java. 1) Using while loop 2) Using for loop 3) Using recursion 4) Reverse the number without user interaction. Java program to reverse a number using for, while and recursion. By Chaitanya Singh| Filed Under. Java program to display prime numbers from 1 to 100 and 1 to n.

The statement
i++ is unreachable, so you don't want the else{..} to contain break . Instead, you simply want else i++ .

Where you want the 'is prime' statement is outside the loop, since you don't know
n is prime until the loop finishes checking all the divisors.
And you don't want
break inside the if ; you want return , because otherwise it'll print 'is prime'.

P.S. You can make the while say
while(i < Math.sqrt(n)) to reduce iterations (think about it). Descargar musica infantil en mp3.
EDIT
You might want to make the return type DSlomer64DSlomer64
boolean instead of printing messages, putting return false if there's a divisor and return true if there was no divisor.

this method will return a boolean if your number is prime or not. In the for loop you can see that we first test 2. Dmc 5 skins and perks free download. If our number isn't divisible by two then we don't have to test any even numbers. This is a very efficient way to test for prime numbers.

The problem is that you break out of the loop on the first check: you divide by 2 and report the answer based only on that.
Restructure your loop so that the decision 'It's a prime number' is delayed until you get all the way through the loop. You may want to set a boolean variable for this.
Also, I recommend using a for loop, since you know the maximum number of times you'll iterate. Note that you don't have to go to n-1, just to sqrt(n).

You can do the while loop in this way, first you want to check if no is divisible by 2, if so it is not a prime number. If not check for odd nos till square root of n. Dont need to check for even, if no is not divisible by 2 it will not be divisible by any even number.
