Question

我正在制作一款战略游戏，用于与星球大战的战斗前线2.这是一个完全不同的程序，所以你需要对游戏一无所知来帮助我。所有你需要知道的是iostream如何工作和字符串比较if语句。

`#include "stdafx.h"
#include <iostream>
using namespace std;


int _tmain(int argc, _TCHAR* argv[])
{
    char Era[]="n";
    int eranumber=0;
    char* content [4] [28];
    char action[]="n";
    char whichplanet[]="n";
    char facilitytype[]="n";

Answer 1

strcmp会返回int类型的值而不是boolean类型。

如果strcmp两者相同，则strings会返回 0 ，否则会返回+ve或-ve个数字，具体取决于两个strings。

所以你需要写：

if (strcmp(Era,"kotor")==0)
{
    eranumber=0;
}

if (strcmp(Era, "swotor")==0)
{
    eranumber=1;
}

if (strcmp(Era,"cw")==0)
{
    eranumber=2;
}

if (strcmp(Era, "gcw")==0)
{
    eranumber=3;
}

另外请记住strcmp区分大小写（即“A”根据此不等于“a”）。如果您想忽略这种情况，请改用strcmpi。

注意：在strcmp

中定义了strcmpi和<string.h>两件事

字符串比较if语句被忽略
