const char * tag1[]={"abc","xyz"};
how to convert tag1 in std::string?
std::string tag2(tag1)
it simply copies tag1[0] to tag2. what i want is to convert the whole tag1 array into string.
Any ideas or workaround?
Since you want to merge array of C-strings into one std::string, you can do this:
std::string tag2;
for (auto ptr : tag1) {
tag2.append(ptr);
}
Iterate over C-strings array and append them to destination std::string.
Direct copy of tag1 array to pre-allocated std::string won't work because of null-terminators at end of each C-string in tag1. You will get abc\\0xyz
, instead of abcxyz
