到达字符串中的特定单词 [英] Reaching a specific word in a string

问题描述

您好，我有这样的字符串：

Hi I have a string like this:

word1 - tab - word2 - -word4 - tab - word5 - tab - word6

word1--tab--word2--tab--word3--tab--word4--tab--word5--tab--word6

我需要从字符串中提取第三个字。我想到按字符阅读字符和读取第二个选项卡后得到的单词。但我想它是低效率的。

I need to extract the third word from the string. I thought of reading character by character and getting the word after reading the second tab. But I guess it is inefficient. Can you show me a more specific way please?

推荐答案

假设tab是 \t ;

std::istringstream str(".....");
std::string temp, word;

str >> temp >> temp >> word;
