Part A - The effect of an arithmetic shift on signed numbers
Let's look at see what happens to signed numbers during a shift operation.
As with most problems with number representations, errors can be intermittent. Sometimes the code will work as expected, and other times it will behave in a manner that seems to be totally arbitrary. Consider the following code fragment that makes use of the fact that shifting a
value left by one place multiplies the number by 2. By passing in the number to be multiplied and the power of 2 to multiply it by (for example 4 = 22) the correct answer should be passed back from the function after the results are printed for the user to examine.
signed int mult_2_to_n (signed int num, int n)
{
signed int result;
result = num << n;
printf("%d multiplied by 2^%d %d\n", num, n, result);
return result;
}
Using a signed number as the manipulated integer may cause an error in some cases. Several approaches may be used to fix the problem. Which solutions below…

I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line.

- What is the difference between the statements continue and break?arrow_forwardDO NOT USE EXISTING ANSWERS ON CHEGG OR COURSE HERO OR ANY OTHER SERVICES PLEASE! Thanks :) CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit. Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated.

You are required to write a program which accepts an operation code, and zero to two inputs depending on the operation code. Based on the operation code, you will call three versions of the overlaoded function textProcessing as follows: Operation 0: The function removes all vowels from the ORIGINAL sentence. The vowels considered are the small letters (a, e, i, o, u y, and w). Operation 1: The code further asks for one lowercase letter to be input by the user. If the character is not a lower case letter, the code outputs Invalid. The function returns the distance (difference) between the letter first occurence and last occurence in the text. If the letter does not occur in the sentence, it returns 0. Operation 2: The code asks for two…arrow_forward
