Someone suggested that we both write a program to find the next prime number after 2.2 billion. Sounded like fun to us so we went at it. Now let the discussion begin. My solution was written in Visual Basic – of course. Clint’s in C# – not a bad choice at all. Clint went...

The following is a pseudo-code version of the COBOL program. I’d reprint the original, but COBOL is very wordy and space consuming and why waste all of that space on a bad example. Further, not a whole lot of people know COBOL. INPUT a number (input_number); failure_flag := FALS...
3. If every digit of my secret code is a different prime number, my secret code has at most ? digits. A)4B)5C)6D)7 相关知识点: 试题来源: 解析 A) 4 秘密代码的每位数字必须是不同的质数。0-9 中的质数只有 2, 3, 5, 7,因此最多只有 4 个不同的质数可用。所以,秘密代码最多有 4 ...
