小编Ros*_*han的帖子

我是一个初学者,刚开始使用JSP而且我一直坚持起步.请帮帮我.我已下载catalina.bat并setclasspath.bat在适当的位置,/tomcat/bin/ 但仍然得到授权错误.我看过一个类似的帖子并tomcat-users.xml用这一行编辑了我<user username="root" password="1234" roles="manager-script"/>

但仍然无法成功运行它.

See the server log for details.

我试图在一些测试中解决这个问题,但后来当我在家里运行时,它给出了意想不到的答案.我无法理解这段代码:

#include <stdio.h>
#include <conio.h>
#define swap(a,b) temp=a; a=b; b=temp;
int main()
{
int i, j, temp;
i=5;
j=10;
temp=0;
if( i > j) //evaluates to false
swap( i, j );
printf( "%d %d %d", i, j, temp); //expected output: 5 10 0
getch();
return 0;
}

我得到的输出是:10 0 0

请有人解释它是如何工作的.

这是我的字符串c:编程很有趣,但不是ABAP.我写的声明是针对单个字符的

REPLACE ALL OCCURRENCES OF REGEX '\m' in c WITH '@'.

工作正常,但如何使用相同的语句替换其他单个字符.

例如:我需要使用一个替换语句替换'm','i'.我怎么写这个,因为REPLACE ALL OCCURRENCES OF REGEX '\m\p' in c WITH '@'.不工作

PS:ABAP学习的新手.
