Implement a revert function which takes a string as input, on output, it reverts the characters in the input string. e.g. "Hello" becomes "olleH"

char * revert ( char * s )
{

#include <iostream>
#include <cstdlib>
#include <string>

using namespace std;

const int SIZE = 100;
void revert(char *s);

int main()
{
char str[SIZE];
cout << "input a string:\n";
cin.getline(str,SIZE);


revert(str);

cout << "After reverting the string it becomes " << endl
<< str << endl;


system("PAUSE");
return 0;
}

void revert(char *s)
{
char temp;
for (int i=0,j=strlen(s)-1; i<j; ++i,--j)
{
temp = s[i];
s[i] = s[j];
s[j] = temp;
}

}
[/CODE]

这样行不行。

不错
