Title: Arithmetic of random numbersIdea: Take two random integers, put the operation symbol in an array, then take a random number, divide by 4, and select the budget symbol by the remainder. The arithmetic of a true fraction is to take four random integers, and to determine the size, the denominator of the true fraction is greater than its numerator.Code:#include #include using namespace Std;void Main (){Srand (Time (NULL));for (int i = 1; i {int a = rand ()%25+1;int b = rand ()%25+1;int c = ra

Test conditions: The range of random number values1, when negative and 0 o'clock prompts re-enter2. When the number of topics is greater than the range of random numbers, such as 1 o'clock, produces the same arithmetic relationship3. When entering letters and other special characters, the program crashes4, when the input value is too large, prompt re-input (the maximum value of 99999999999999, 14 9)Through this test found that their program is not strong enough, a lot of bugs, the late should be

There is no perfect code that means that we are constantly optimizing to get closer to perfection, so software testing is especially important.In the previous concept I have always thought that software testing is done after the completion of the software, after two sessions I have a new understanding of software testing.The purpose of software testing is to evaluate the properties or abilities of a program or system, and to determine that it conforms to its own desired results.A few lines of co

Title Address: HDU 2242The two-connected component is used to shrink the point, then a tree is formed, and then a tree DP is made on the tree to find out the subtrees of each point. Then find the minimum value. Note the problem of heavy edges, which can be ignored the first time you return to the parent node, because this is a reverse edge, and then it is not reversed when you return. Can't ignore it.The code is as follows:#include HDU 2242 Entrance Examination Road boundless--air-conditioning
