< cpp | experimental | basic string view
| constexpr void remove_suffix(size_type n); |
(library fundamentals TS) | |
Moves the end of the view back by n characters.
The behavior is undefined if n > size().
Parameters
| n | - | number of characters to remove from the end of the view |
Return value
(none)

Example
Run this code
#include <iostream> #include <experimental/string_view> int main() { char arr[] = {'a', 'b', 'c', 'd', '\0', '\0', '\0'}; std::experimental::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=7 View : 'abcd', size=4
