c does not use exceptions. what is commonly used instead (in the standard library, for example) to indicate whether a function has succeeded or failed? what represents success, and what represents failure?

Answers

Answer 1

Error handling is not directly supported by C. (also known as exception handling).

By convention, the programmer is required to test function return values and take steps to avoid mistakes from happening in the first place. Both exception handling and error handling are not supported by the C programming language. It is an added service provided by C. Although this feature is missing, there are still ways to provide error management in C. In general, most functions either return a null result or -1 in the event of an error. Although error handling (or exception handling) is not directly supported by C, there are nonetheless ways to handle errors in the language. A programmer must start by eliminating errors.

given the list (xlsx, xls, xlr, txt, ods), what is the order of the elements after completing insertion sort's second outer loop iteration?

Answers

After completing the second outer loop iteration of the insertion sort algorithm on the given list, the order of the elements will be ("xls", "xlr", "xlsx", "txt", "ods").

In the second outer loop iteration of the insertion sort algorithm, the first two elements are already sorted, so the algorithm will compare the third element, "xlr", with the first two elements, "xlsx" and "xls", to determine the correct position to insert it. Since "xlr" comes before "xlsx" and after "xls" alphabetically, it will be inserted between the two. The list will then become ("xls", "xlr", "xlsx", "txt", "ods").

Therefore, after completing the second outer loop iteration of the insertion sort algorithm on the given list, the order of the elements will be ("xls", "xlr", "xlsx", "txt", "ods").

timer a is using aclk configured to a 16 khz (16,384 hz) crystal. what is the timer period if the continuous mode is used? give the answer for all the values of id (input divider).

Answers

The following formula is used to get the timer period (T):

T = (id/f clk) where "f clk" is the clock frequency and "id" is the input divider value

In this instance, the input divider can be set to 1, 2, 4, or 8 and the clock frequency is 16,384 Hz.

The timer period for each input divider value can be determined using the formula as follows:

T = (21 / 16,384) = 0.00012207 seconds when id = 1 (or 122.07 microseconds)T = (22 / 16,384) = 0.00024414 seconds when id = 2 (or 244.14 microseconds)T = (24 / 16,384) = 0.00097656 seconds when id = 4 (or 976.56 microseconds)When id is equal to 8, T equals (28 / 16,384) = 0.00409668 seconds (or 4.09668 milliseconds)

As a result, the timer period for the continuous mode can range from 122.07 microseconds to 4.09668 milliseconds depending on the input divider value.

By specifying an object's key locations and transformations at certain points in time, keyframe animation allows the computer to interpolate the motions and transformations between those key frames.

The precise movement of the airplane along the predetermined path can be controlled using this style of animation.

You examine what is anticipated for this reason. A worst-case scenario analysis simply considers the input. We rarely have complete control over how an algorithm will be used, therefore we frequently are unable to derive an average-case measurement that is likely to be accurate. The worst-case scenario provides us with a performance upper limit. An algorithm will never do worse than what we determine if its worst case analysis is done.
