An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container format or an audio data format with a defined storage layer.

In a computer program, loops are used to perform repetitive operations until a condition is met.

The nested loop structure to use in this case is: A "while" loop inside of a "for" loop

The outer loop

First, you must iterate through each student.

This can be done using a for loop or a while loop.

However, it is faster to implement this kind of iteration on a for loop, than a while loop

So, the algorithm of the outer loop would look like the following:

for student = 1 to 5 step 1

The inner loop

Next, you must get input for the 5 grades for each student

After getting input for the grade of each student, a loop would be used to test if the input is valid.

The loop would be repeated until the user enters a valid input.

This can only be done using a while loop.

So, the algorithm of the inner loop would look like the following:

input grade

while grade is invalid:

input grade

Hence, the nested loop structure to use is:

A "while" loop inside of a "for" loop

1. Describe a linear search (explain how it works).

timurjin [86]

1. A linear search searches on a straight path, hence the term “linear”. So a linear search would search from a one index to another in a straight path. For example, a linear search of an array, if given given the first and last index of the array, would search it one index after the other. First it would check index 0, then index 1, then index 2, and so forth.

2. A linear search can be useful if you are trying to find more than one instance of an value in a data structure. Since you want to search the whole array for each instance of the object or value.

3. A binary search only works with sorted data structures. It takes a data structure, finds its mid point, and checks I see if the value it is looking for is greater, less than, or equal to the midpoint value. If it is equal to the midpoint value, it’s finished and the search function is over.
If it’s greater than the midpoint, it disregards the lower half of the data structure and focuses on the upper half. If it’s less than the mid point then it disregards the upper half and focuses on the lower half.
It then repeats what it did at the beginning of the search function to again narrow down the amount of searching that needs to be done. In other words, if it disregarded the lower half of the data structure in the first part of the search, it finds the midpoint of the upper half of the data structure, checks to see if the value it’s looking for is greater than, less than, or equal to the midpoint. If it’s equal to it the searching is done, if it’s greater it disregards the lower half of the upper data structure, and repeats the process.
It will continue to do this until either the value is found or the value is not found.

4. You would use binary search if you are searching for one specific value in a sorted data structure.

5. A binary search must have a sorted data structure for it work.

6. Binary search is more efficient because the cost to run a binary search is substantially less than running a linear search.

Declare an array named tax rates of five elements of type double and initialize the elements (starting with the first) to the va

inysia [295]

Answer:

"double tax_rates[5]= {0.10, 0.15, 0.21, 0.28, 0.31};" is the correct answer for the above question.

Explanation:

An array is a user-defined data type that is used to define the multiple variables of a single type in a continuous storage location.
In the C-programming language, When the user wants to declare an array he needs to define with the help of data type and size of the array with the help of the following syntax-- "Data_type variable_name [size_of_the_array];".
When the user wants to initialize the static value in the array then he can do that by the help of following syntax: "Data_type variable_name [size_of_the_array]={first_value,second_value,....,last_value};
The above question asked to defined the array of tax_rates name of type double with the above-defined value then he can do that with the help of above-defined syntax (which is defined in the answer part).
