Among positive even number only 2 is the prime number rest of all the prime numbers are odd(positive) number.
#include<stdio.h>
int main()
{
int number,i,j,primeNumber,low=1,high=100;
printf(" Prime Numbers are: \n");
for(j=low;j<=high;j++){
primeNumber=0;
for(i=2;i<=j/2;i++){
if(j%i==0){
primeNumber++;
break;
}
}
if(primeNumber==0 && j !=1)
printf("%d\t ",j);
}
return 0;
}
output:
Prime Numbers are:
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
