#include <iostream>#include <string_view> int main(){char arr[]={'a','b','c','d','\0','\0','\0'};std::string_view v(arr, sizeof arr);auto trim_pos= v.find('\0');if(trim_pos!= v.npos) v.remove_suffix(v.size()- trim_pos);std::cout<<"Array: '"<< arr<<"', size="<< sizeof arr<<'\n'<<"View : '"<< v<<"', size="<< v.size()<<'\n';}
Output:
Array: 'abcd', size=7View : 'abcd', size=4
| shrinks the view by moving its start forward (public member function)[edit] |
