字符串 c++ == 比较

Question

    char words[5] = { 't', 'd' , 'o', 'g', 'i', };
    cout << "enter letter ";


    char dogsearch[3] = { 'd', 'o', 'g' };

    if (words == dogsearch)
        cout << "found words";
    else
        cout << "Not found word";

我有两个数组并将它们相互比较以找到彼此之间的相似性和差异，如果有相似性，我想输出它是如何的，反之亦然

Answer 1

您可以使用 string::find 查找子字符串匹配项

char words[5] = { 't', 'd' , 'o', 'g', 'i', };
char dogsearch[3] = { 'd', 'o', 'g' };

string words_str(words, sizeof(words));
string needle(dogsearch, sizeof(dogsearch));

size_t pos = words_str.find(needle);
if (pos != std::string::npos)
   cout << "found words at position " << pos << '\n';
else
   cout << "Not found word;
