Not long ago, I applied to join an open source organization, they asked me to write a function to detect whether there is a Trojan script in the picture. In fact, I do not know at the beginning of anything, but later on the Internet to check some

first we have a general view of Rand&srand: Srand initializes random seeds, Rand generates random numbers, which are explained in detail below.  rand (generates random numbers) table header files: #include  define function: int rand (void) function

First, the topicPlease write a "software" that can automatically generate primary arithmetic topics.Allow the program to accept the user to enter the answer, and determine the right and wrong.Finally, the total number of pairs/errors is given.Second,

Writing this algorithm is very simple, and the principle is very simple, but the trap is used in this algorithm for arrays, access and control of the underlying object. Generally, merge sorting uses 1 as the subscript, but today we want to use 0 as
