质数计算打印程序代码

话不多说。直接上代码。

int printPrimaryNumber(int nUpperBound)
{
    int iTotal = 0;

    // Primary number start with 2.
    for (int i = 2; i <= nUpperBound; i++)
    {
        bool isPrimary = true;
        for (int j = 2; j < i; j++)
        {
            if (i % j == 0)
            {
                isPrimary = false;
                break;
            }
        }
        if (isPrimary)
        {
            iTotal++;
            printf("%d, ", i);
        }
    }
    printf("Total: %d.
", iTotal);
    return 0;
}
