我想填补一个std::map,但我得到2个编译器错误,我不知道原因是什么.
std::map<std::string, std::string> dirFull;
dirFull["no"] = "north";
dirFull["so"] = "south";
dirFull["ea"] = "east";
dirFull["we"] = "west";
dirFull["nw"] = "north-west";
dirFull["ne"] = "north-east";
dirFull["sw"] = "south-west";
dirFull["se"] = "south-east";
这些是错误:
error: C++ requires a type specifier for all declarations
dirFull["no"] = "north";
^
error: size of array has non-integer type 'const char[3]'
dirFull["no"] = "north";
^~~~
std::map<std::string, std::string> dirFull = {
{"no", "north"}, {"so", "south"},
{"ea", "east"}, {"we", "west"},
{"ne", "north-east"}, {"nw", "north-west"},
{"se", "south-east"}, {"sw","south-west"} };
这会导致完全不同类型的错误: …
