#include <iostream>

using namespace std;

int main()
{
    int vovles_count[5] = { 0,0,0,0,0 };
    char vovwls[5] = { 'a','e','i','o','u' };
    char vov;
    int nonVov = 0 , punt = 0 , douseq = 0;

    //std::cin >> std::noskipws; //tells not to skip white spaces

    while (cin >> vov)
    {
        switch (vov)
        {

                else if (vov == 'i')
                {

                    ++douseq;
                    ++nonVov;   //previous f

                else if (vov == ' ' || vov == '\n')

                break;
            default:
                ++nonVov;
                break;

        }
    }
    for (int i = 0; i < 5; ++i)
    {
        cout << vovwls[i] << " occured for " << vovles_count[i] << "times" << '\n';
    }
    cout << '\n' << nonVov << " are the occurence of non vovels " << '\n' ;
    cout << '\n' << punt << " are the occurence of whitespaces " << '\n';
    cout << '\n' << douseq << " are the occurence of double sequence " << '\n';


    system("pause");
    return 0;
  }

我不认为我在代码中看到任何问题，但我不知道为什么没有读取空格？

Answer 1

使用cin默认会跳过空格。你可以尝试其他方式：

cin.get();

这个函数的代码重载对你有帮助：

istream& get (char* s, streamsize n, char delim);

将'\ n'放在delim中以在输入

时结束输入行

没有读取空格
