}exception out of range c
Defines a type of object to be thrown as exception.
It reports errors that are consequence of attempt to access elements out of
defined range.
It may be thrown by the member functions of std::bitset and std::basic_string,
by std::stoi and std::stod families of functions,
and by the bounds-checked member access functions
(e.g. std::vector::at and std::map::at).exception out of range c
class out_of_range : public logic_error {
public:
explicit out_of_range (const string& what_arg);
};
EX.
// out_of_range example
#include <iostream> // std::cerr
#include <stdexcept> // std::out_of_range
#include <vector> // std::vector
int main (void) {
std::vector<int> myvector(10);
try {
myvector.at(20)=100; // vector::at throws an out-of-range
}
catch (const std::out_of_range& oor) {
std::cerr << "Out of Range error: " << oor.what() << '\n';
}
return 0;
}exception out of range c
Replace throw std::out_of_range; with throw std::out_of_range ("blah");. I.e. you need to create an object, you cannot throw a type.Copyright © 2021 Codeinu
