**Print prime numbers between 1-300 using break and continue in c**

#include <math.h>

#include <stdio.h>

main(){

int i, j;

i = 2;

while ( i < 300 ){

j = 2;

while ( j < sqrt(i) ){

if ( i % j == 0 )

break;

else{

++j;

continue;

}

}

if ( j > sqrt(i) )

printf("%d\t", i);

++i;

}

return 0;

}

**Definition of prime number:**

A natural number greater than one
has not any other divisors except 1 and itself. In other word we can say which
has only two divisors 1 and number itself. For example: 5

Their divisors are 1 and 5.

Note: 2 is only even prime number.

**Example of prime numbers :**2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199 etc.

is it possible without break and continue

ok priya...its working

Deletethinking great

please guide me to understand the ''fact'' command..... I could not understand it...

Deleteis it possible to use some other function instead of main??

ReplyDeleteits ok......

ReplyDeletesend program to print series 1+(1+2)+(1+2+3)+(1+2+3+n)in c language

ReplyDeleteinitialise i=2 instead of i=1, otherwise 1 also print in prime no series.

ReplyDeleteThanks!

Deletesuppose any number is given eg:a=12345 then addition of first number and last number eg:1+5=6 like this ,so early as possible....
