Answer 1

NinjaGamer ,

How should one use that? It returns True, False, or an integer.

Testing it with this call,

for n in range(12):
print(n, p(n))

produces this output.

0 False
1 True
2 False
3 3
4 False
5 True
6 False
7 True
8 False
9 3
10 False
11 True

Does that mean it thinks 1 is prime and 2 isn't? What should the caller do when it returns 3?

Answer 2

#include <stdio.h>
int main()
{
int x,y,z;

for(x=3;x<100;x++)
{
z = 0;

for(y=2;y<x;y++)
{
if(x%y==0)
{
z = 1;
break;
}
}

if (z == 0)
printf("prime num are: %d\n",x);
}

return 0 ;
}

Answer 3

This is a very efficient Python function.

import math
def p(n):
i = 1
if n % 2 == 0:
return False

while i < math.sqrt(n):
i+=2
if n % i == 0:
return i
return True
