推荐答案

您已经有一个 C 答案，这是一个 C ++ 答案:

Hi,
You already have a C answer, this is a C++ one:

#include <string>
#include <iostream>
void PrintReverseShorten(const char* str)
{
    std::string temp(str);
    while (temp.length())
    {
        std::cout << temp << std::endl;
        std::reverse(temp.begin(), temp.end());
        temp.erase(--temp.end());
    }
}
int main()
{
    PrintReverseShorten("12345");
    return 0;
}

尝试类似的方法:

Try something like this:

int main(int argc, char *argv[])
{
    char* word = "12345";
    
    int start  = 0;
    int finish = strlen(word);
    int direction = 1;
    int i = 0;
    
    while (start < finish) {
        if (direction == 1) {
            finish--;
            for (i = start ; i <= finish ; i++)
                printf("%c" , word[i]);
        }
        else {
            start++;
            for (i = finish ; i >= start ; i--)
                printf("%c" , word[i]);
        }
        direction=-direction;
        
        printf("\r");
        getchar();        
    }
    return 0;
}

我想有更好的方法来实现它，但我尝试使其保持简单.

祝你好运.

I guess there are better ways to accomplish it but I have tried to keep it simple.

Good luck.
