问题描述

c++问题 指向字符串的指针

#include "stdafx.h"
#include
#include
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
char *s = "Hello";
char *t = "World";
int i = strcmp(s, t);
if (i > 0)
cout << "s>t" << endl;
else if (i < 0)
cout << "s<t" << endl;
else
cout << "s=t" << endl;
int j = strlen(s);
cout << endl;
cout << "字符串s的长度为：" << j << endl;
return 0;
}
Error 2 error C2001: newline in constant 22 1

Error 3 error C2143: syntax error : missing ';' before 'return' 23 1
Warning 1 warning C4819: The file contains a character that cannot be represented in the current code page (936). Save the file in Unicode format to prevent data loss

求高手改错，不胜感激！

解决方案

解决方案二：

用的什么编译器，VC6的话就把所有的变量声明都写在前面

解决方案三：

我运行也没问题

解决方案四：

#include "stdafx.h"
#include
#include
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
char *s = "Hello";
char *t = "World";
int i = strcmp(s, t);
if (i > 0)
cout << "s>t" << endl;
else if (i < 0)
cout << "s<t" << endl;
else
cout << "s=t" << endl;
int j = strlen(s);
cout << endl;
cout << "字符串s的长度为：" << j << endl;
return 0;
}

"Microsoft Visual Studio 2010"编辑正确通过。

解决方案五：

没问题可以运行，你的头文件不是故意漏掉的吧
