我知道以前有人问过这个问题，但是对于提问者的代码，答案似乎过于具体。
如果这被认为是一个无用的重复问题，请随时将其删除或将其标记为重复。
据我所知，我的代码对于我想要实现的目标是正确的，即计算文本文件中指定单词的出现次数。我会很感激任何帮助，谢谢。
错误

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
我的 main.cpp 的一部分（导致问题）
//vectors to hold words from two files
vector<string> wordlist;
vector<string> file;
vector<int> searchVec;
//while a is not an empty string
while (a != "") {
//getNextWord() returns each word in order from a text file
//a is a play script, b is a list of words to search for
a = infile.getNextWord();
b = infile2.getNextWord();
file.push_back(a);
//counts total words in play script
count++;
//increments and adds each word from the list of words to search for to the vector
for (int i = 0; b != ""; i++) {
wordlist.push_back(b);
}
//cycles through words to search for
for (int j = 0; j < wordlist.size(); j++) {
//cycle through te play script
for (int k = 0; k < file.size(); k++) {
//if the current play script word is the same as the test word, up the count
if (file[k] == wordlist[j]) {
searchCount++;
}
}
//print appropriate output, re-initialise the count to 0 for the next word
cout << "The word " << wordlist[j] << " occurs " << searchCount << " times." << endl;
searchCount = 0;
}
}
