class bad_array_new_length;
Exception on bad array length
Type of the exceptions thrown by array new-expressions in any of these cases:
- If the array size is less than zero.
- If the array size is greater than an implementation-defined limit.
- If the number of elements in the initializer list exceeds the number of elements to initialize.
This class is derived from bad_alloc (which is itself derived from exception ). See the exception class for the member definitions of standard exceptions.
Its member what returns a null-terminated character sequence identifying the exception.

// bad_array_new_length example
#include <iostream> // std::cout
#include <exception> // std::exception
#include <new> // std::bad_array_new_length
int main() {
try {
int* p = new int[-1];
} catch (std::bad_array_new_length& e) {
std::cerr << "bad_array_new_length caught: " << e.what() << '\n';
} catch (std::exception& e) { // older compilers may throw other exceptions:
std::cerr << "some other standard exception caught: " << e.what() << '\n';
}
}
Possible output:
bad_array_new_length caught: bad array new length
Exception safety
No-throw guarantee: no members throw exceptions.
