c++ - C++ 中 char* 中的子字符串，strtok 到行尾

Question

我尝试在 C++ 中 cat 键入 char* 的字符串 这是我的代码

void DBManager::printMatched(char* line, char* fileName)
{
    line = strtok(line,"Show");
    char* teamAName = strtok(line," ");
    char* teamACity = strtok(NULL,"-");
    char* teamBName = strtok(NULL," ");
    char* teamBCity = strtok(NULL,"\n");
}

这是一行中的文字 “显示 abcde fghij - klmnop qrstu”

这是变量数据:

 teamAName = abcde
 teamACity = fghij
 teamBName = klmnop
 teamBCity = qrs

我如何修复 teamBCity 我需要切到行的内部。

我在 Linux 系统上工作。

我想这就是你想要的。鉴于您的示例，不完全确定。它显然可以改进，也许您想使用更多的 c++ 工具？

void DBManager::printMatched(char* line, char* fileName)
{
    char* linecpy   = strdup(line);

    char* dummy     = strtok(linecpy," ");
    char* teamAName = strtok(NULL," ");
    char* teamACity = strtok(NULL," ");
          dummy     = strtok(NULL," ");
    char* teamBName = strtok(NULL," ");
    char* teamBCity = strtok(NULL," \n");

    printf("teamAName %s\n", teamAName);
    printf("teamACity %s\n", teamACity);
    printf("teamBName %s\n", teamBName);
    printf("teamBCity %s\n", teamBCity);

    // do something with strings here?
}
