如何在C ++中查找字符串中的行 [英] how to find a line in a string in C++

问题描述

#include<iostream>
#include<string>


using namespace std;

int main(){
string sSentence;
sSentence = "this is a string";

int iVowel = sSentence.find_first_of("aeiou");

while(iVowel!=string::npos){

}
}

所以这是未完成的代码。



我们的任务是制作一个关于piglatin的程序：



首先找到第一个一个单词的元音

将所有字符放在句子最后一个字母后的第一个元音之前然后添加ay

例如：编码==== odingcay



问题：

1.找到第一个元音后，如何在第一个元音之前得到字符。



2.翻译单词后，如何跳转到下一个单词。 （当我找到下一个单词的第一个元音但我不知道如何找到那个空格时，我想用空格作为起点）。



pls救命。谢谢：）

so this is the unfinished code.

The program that was tasked of us was so make a program about piglatin:

first find the first vowel of a word
put all the characters before the first vowel after the last letter of the sentence then add "ay"
example: coding ==== odingcay

Problems:
1. after finding the first vowel, how do I get the characters before the first vowel.

2. after translating the word, how do I jump to the next word. (I was thinking of using the blank space as the starting point when finding the next first vowel of the word but I dont know how to find that space).

pls help. thank you :)

字符串类有许多有用的成员函数可以操作其内容，如上所述在 https://msdn.microsoft.com/en-us/library/syxtdd4f.aspx [ ^ ]。熟悉MSDN对开发人员来说总是有用。

The string class has many useful member functions that can manipulate its content, as described at https://msdn.microsoft.com/en-us/library/syxtdd4f.aspx[^]. Getting familiar with MSDN is always useful to a developer.
