Code:
#include iostream
const int len = 100;
int main()
{
int arr[100] = {0};
for (int i = 2; i < 100; i++)
{
for (int j = i * i; j < 100; j+=i)
{
arr[j - 1] = 1;
}
}
for (int i = 1; i < 100; i++)
{
if (arr[i - 1] == 0)
std::cout << i << "\t";
}
}
Output:
1 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
