我有一个值为的字符串name:score.我想将字符串拆分为两个字符串,字符串a的值为值,name字符串b的值为score.
执行此操作的正确函数/语法是什么?
我已经看了string.split,但找不到实际的语法将数据返回到两个单独的字符串中.
我有以下代码;
#include <stdio.h>
#define MAXLINE 2600
char words[4][MAXLINE];
int i;
int main(){
printf("Enter menu option: ");
scanf("%s", words[i]);
printf ("\n %s was entered!", words[i]);
if (words[i]=="help"){
printf("\nHelp was requested");
}
else
{
printf("\nCommand not recognized!");
}
}

if语句中的数组求值不起作用.我显然做错了什么.有人可以向我解释一下吗?
在以下代码中,$ client = XRS1时
if (Test-Path C:\dbbackups\cm_$client-*.full.bak){
Rename-Item -path C:\dbbackups\cm_$client-*.bak -newname cm_$client.bak
Write-Host "New file found, renamed to: cm_$client.bak"

Test-Path语句可以找到C:\ dbbackups\cm_xrs1-2013414.full.full.bak,但Rename-Item中的-path不能.
我得到的错误是
Rename-Item : Cannot process argument because the value of argument "path" is not valid. Change the value of the "path" argument and run the operation again.

可以通过单击列名称对列进行按字母顺序排列,但如何将站点设置为自动按字母顺序排列第一列?
我编写了这个程序来将EDI文件切割成他们自己的文件,但它并没有这样做.有时它会将包含三个部分的文件分成两个部分,有时则会找到所有三个部分.
任何人都可以向我解释为什么这样做?任何帮助是极大的赞赏.
