Question

C++输入一字符串，要求逆序输出

帮我看哪里错了，＼谢谢指点

#include "iostream"
using namespace std;
#include <string>
#include "math.h"
int main()
{int t,i;
string string1;
cin >>string1;
char str[]=string1;
t=sizeof(string);
char m;
if ((t-1)%2==0)
{for(i=0;i<=(t-1)/2;i++)
{m=str[i];
str[i]=str[t-i-1];
str[i-1]=m;}
}
else
{for(i=1;i<=(t+1)/2;i++)
{m=str[i];
str[i]=str[t-i-1];
str[i-1]=m;}}
cout <<str[i];
return 0;
}

Answer 1

呵呵，一楼的不就是一个逆序输出么，没有存起来呵。
也没有按要求来做呵

Answer 2

------ Build started: Project: node, Configuration: Debug Win32 ------
Compiling...
main.cpp
e:\documents\visual studio 2008\projects\node\node\main.cpp(10) : error C2440: 'initializing' : cannot convert from 'std::string' to 'char []'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

char str[]=string1;
这句错了。
这样是不可以的。

不就是要逆序输出嘛？你都用上了string类了哪还需要这么麻烦啊？

#include "iostream"
using namespace std;
#include <string>

int main()
{
string string1;
cin >>string1;
for(int i=(int)string1.size()-1;i>=0;i--)
{
cout<<string1[i];
}
return 0;
