Numbers which do not have factors without 1 and itself are Prime Numbers.
To find prime numbers turn the multiples of 2,3,5,7,11 into bold but not to these numbers.
Remember 1 is not a composite nor a prime no.

01 02 03 04 05 0607 08 09 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 4243 44 45 46 47 48 49 50
51 52 53 54 55 56 57 58 59 60
61 62 63 64 65 66 67 68 69 70
71 72 73 74 75 76 77 78 79 80
81 82 83 84 85 86 87 88 89 90
91 92 93 94 95 9697 98 99 100

The left over numbers which are not bold are Prime Numbers.
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,89,97 are prime numbers.

The numbers which are in bold are Composite Numbers.
4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,
45,46,48,49,50,51,52,54,55,56,57,58,60,62,63,64,65,66,68,69,70,72,74,75,76,77,78,80,
81,82,83,84,85,86,87,88,90,91,92,93,94,95,96,98,99,100 are composite numbers.

A prime number is a positive integer evenly divisible only by itself and one.

No specific method has been discovered so far,not even by the greatest mathematicians,to create a prime number or to find out all the prime numbers......but there's a way to find whether a number is prime or not,i.e,by dividing that number with the first prime nos. such as 2,3,5,7,11 and so on and seeing whether it is exactly divisible or not.If it is not,then it can be classified as a prime no.


All of them are whole nos.


main() { int i,sumo=0,sume=0,oddno,evenno; for(i=1,oddno=1,evenno=2;i<=100;++i,oddno=oddno+2,evenno=evenno+2) { sumo=sumo + oddno; sume=sume + evenno; } printf("Sum of odd nos = %d And Sum of even nos = %d,sumo,sume); }

Latin is a very specific and precise language. If something were literally placed on the ground between you and me, it would be inter nos, in between us.You probably want to say "among us", which is ad nos or apud nos.


Basically there is not a whole lot of difference between OS and NOS. In common usage OS or Operating System is concerned with one computer. That is the simplified answer. An OS can have NOS features when it interfaces with other computers.



if (*&a > *&b) *&max = *&a; else *&max = *&b;


"Among us" or "between us".

Quantos a~nos tiene Usted? Or Quantos a~nos tienes? [The tilde accent is over the "n," not between the "a" and the "n."]


The difference is using a NOS ( Network Operating System), A Domain uses a NOS whereas a Workgroup does not.
