Design ideasThe function is used to encapsulate the code of the maximum value of the array, and the function is called in the main function.SOURCE program code#include using namespace Std;int largest (int list[],int length){int i;int max=list[0];for (i=0;i{if (List[i]>max){Max=list[i];}}return Max;}void Main (){int I,max;int x[5];coutfor (i=0;i{cin>>x[i];}coutMax=largest (x,5);cout}TestTestIssues found1. When entering floating-point data, the integer portion of floating-point type is used by def

I had to deal with regular expressions almost all the time, so I got this test practice page. Save the following code as an HTML file and use IE to open it: "Http://www.w3.org/TR/html4/loose.dtd" >

It was almost all about regular expressions, so I got this test practice page at the time. Save the following code as an HTML file and use IE to open it: "Http://www.w3.org/TR/html4/loose.dtd" >

performance, this step is the most critical, Implement the SQL statement as follows:Selectname,sum( Case whenCourse='Java' ThenGradeEnd) as 'Java',sum( Case whenCourse='C + +' ThenGradeEnd) as 'C + +' fromScoreGroup byNameOperation Result:2, then through the construction of a subquery, that is, the above 1 query results as a table to query, where row-level filtering is possible, the implementation of the SQL statement is as follows:Select * from(Selectname,sum( Case whenCourse='Java' The

Practice: Implement a first in, out shared memory ShmfifoMessage Queuing is used to implement the FIFO of the message, but it is faster to use shared memory for the FIFO of the message;We first complete the C language version of Shmfifo (based on the procedure call), and then implement the C + + version of Shmfifo on this basis, will be 1 blocks of shared memory with 3 semaphores (1 mutext semaphores, 1 full semaphores, 1 empty semaphores) Encapsulate
