/* 2. programming questions1) input a string from the keyboard, and change the upper-case letters to lower-case letters, lower-case letters to upper-case letters, and output.[Requirement](1) Use a character array to store strings (the maximum value of a string is 100 ).(2) Use the scanf function to input characters one

You cannot use the switch statement in ASP, you need to use the Select Case statement A Brief introduction Select the work of the report, if the statement. The difference, however, is that they can check for multiple values. Of course, you haveMany of the same, if. Else statement, but this is not always the best method.The SELECT statement allows a program to evaluate the expression and attempt to match the value of the expression to the

The last one said we had a preliminary business analysis and got the user, business use case and business scenario model. These three outcomes form the basic requirements framework and delineate the scope of the business. A baseline should be made at this time. Of course, the first baseline contains very thick content, and there is more work to be done to achieve the full requirements. This article is about the detailed requirements process and outpu

In C ++, the difference between TRUE in upper case and true in lower case is true in lower case. 1. Differences between TRUE in uppercase and true in C ++True is of the bool type;TRUE is int type, which is defined by ms in VC; C ++ does not allow two functions to be differentiated by different return types 2. Is there any difference between "false" and "FALSE"

Analysis: high concurrency, large data write data, will write the data into memory, accumulate a certain amount, and then in a timed or quantitative write to disk (reduce the disk IO (input/output)), eventually will load the data into memory and provide external access . Characteristics: Advantages: Write data to memory, high performance, fast speed (Weibo, SNS, Seconds Kill product) Cons: You may lose a piece of data in memory that has not yet been saved to disk ways to resolve data wit

Turn from: Worst case and average situation of the algorithmIf a program runs multiple times, sometimes it will be faster, sometimes it will slow down a bit. The algorithm is the same, in the case of input 1 and input 2, the execution efficiency is not necessarily the same. That is, the algorithm will vary in order and efficiency depending on the input data, sometimes faster and sometimes slower. For exampl

Software test cases have been being collated recently due to project needs. A large number of software test cases and business is not easy to organize, although a considerable amount of practice, but also to harvest some ideas, hope that the future of software testing work can help. In the process of collating test cases, you are thinking about a problem from beginning to end and why these use cases need to be sorted out. How to do so that the people in the back no longer need to organize these

--A useful discussion on use-case model and its application This is a discussion of use case model. How to build a use case model, how to write a use case description, what is the difference between it and the requirements specification, can it replace the requirement specification?
