Using Amazon CloudWatch's Free Tier, what is the frequency of metric updates which you receive?

Which function does not use either the standard input stream or the standard output stream?

a) puts b) getchar c) gettime d) scanf

Find the error in each of the following segments. If the error can be corrected, explain how.

``` a) int* number; b) double* realPtr; long* integerPtr; integerPtr = realPtr; c) int* x, y; x = y; d) char s[]{"this is a character array"}; for (; *s != '\0'; ++s) { cout << *s << ' '; } e) short* numPtr, result; void* genericPtr{numPtr}; result = *genericPtr + 7; f) double x = 19.34; double xPtr{&x}; cout << xPtr << endl; ```
