How do you draw a flow chart to check whether a given number is prime or not?
There are flowcharts available for computers, that depend upon brute number crunching. In other words, they are dividing a given number by every lesser number and seeing if there are any that divide evenly into it. For humans, this is a bit harder. However, here are four steps to let you know if a number can be divided by the numbers 1 through 9 (but not seven). 1. Is it an even number? If yes, then stop, it's not prime. 2. Is it a number ending in zero or five? If yes, then stop, it's not a prime. 3. Do the digits in the number add up to three or nine? If yes, then stop, it's not a prime. Now, any "yes" answer ends it. But if all the above were answered "no", that doesn't actually end it. Maybe the number can be divided by 7. Or 11. Or even larger numbers.
Write a c program to check whether a no is prime or not?
#include<stdio.h> #include<conio.h> int i=1, count=0,n; clrscr(); printf("Enter Any Number"); scanf("%d", &n); while(i<n) if(n%i==0) { count++; i++; } if(count==2) printf("Given Number is Prime"); else printf("Given Number is not Prime"); getch(); }
How can you Write a suitable pseudo code to check whether a number is prime or not?
Begin Read num for(i=2; i<num; i++) if(num%2==0) then print "the number is not a prime no."; else if print "the number is prime"; end if Stop
How do you print non-prime numbers in java?
Loop through some numbers - for example, 2 through 100 - and check each one whether it is a prime number (write a second loop to test whether it is divisible by any number between 2 and the number minus 1). If, in this second loop, you find a factor that is greater than 1 and less than the number, it is not a prime, and you can print it out.
Python function that lists prime numbers?
If you just want a hint: One way to check whether a number is prime is by dividing it by any number between 2 and the square root of your number. If the number divides by any of these, it is not prime. If you want the code: import math for num in range(1,101): if all(num%i!=0 for i in range(2,int(math.sqrt(num))+1)): print num

Why is the 2 on the prime and composite chart special?
No even number greater than 2 is a prime number.
Draw a flow chart of prime number check between 1 to 20?
1. If number < 2 then not prime - end2. If number == 2 then prime - end3. If number divisible by 2 then not prime - end4. If number divisible by 3 then not prime - end5. If number divisible by 5 then not prime6. end (It is not necessary to get any more complicated than this because you only need to check divisibility up to the square root of the number in question, and you only asked about numbers up to 20.)
How do you know 2 is a even prime number?
look it up on a prime chart not composite
Is 31 a prime?

What number in the hundreds chart is not prime nor composite?
One.
A chart of prime numbers?
There is an infinite number of them, so of course there is no chart with all of them. If you google prime number, you can find list of the first 1000 or even 10000 primes. That should do it, I think
