You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

Imagine that you are helping to build a store management system for a fast food restaurant. Given the following lists, write a program that asks the user for a product name. Next, find out if the restaurant sells that item and report the status to the user. Allow the user to continue to inquire about product names until they elect to quit the program.
Answers
Answer:
The program in python is as follows:
def checkstatus(food,foodlists):
if food in foodlists:
return "Available"
else:
return "Not Available"
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
food = input("Food (Q to quit): ").lower()
while food != "q":
print("Status: ",checkstatus(food,foodlists))
food = input("Food (Q to quit): ").lower()
Explanation:
The program uses function.
The function is defines here. It accepts as input, a food item and a food list
def checkstatus(food,foodlists):
This check if the food is in the food lists
if food in foodlists:
Returns available, if true
return "Available"
Returns Not available, if otherwise
else:
return "Not Available"
The main begins here.
The food list is not given in the question. So, I assumed the following list
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
This converts all items of the food list to lowercase
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
Prompt the user for food. When user inputs Q or q, the program exits
food = input("Food (Q to quit): ").lower()
This is repeated until the user quits
while food != "q":
Check and print the status of the food
print("Status: ",checkstatus(food,foodlists))
Prompt the user for another food
food = input("Food (Q to quit): ").lower()

Following are the code to the given question:
def match_sequence(s1,s2):#Defining a method match_sequence that accepts two parameters
for l in range(len(s1)):#defining a loop that checks range of s1 value
if(s1[l] != s2[l]): # use if block to match each sequences
print('The sequence does not match at index: ',l+1)#print value with message
s1 = 'CATCGTCCT'#defining a string varible s1
s2 = 'CACCGACCG'#defining a string varible s1
match_sequence(s1,s2)#calling a method that prints its values
Output:
The sequence does not match at index: 3
The sequence does not match at index: 6
The sequence does not match at index: 9
Explanation:
In this code, a method "match_sequence" is declared that takes two string variable "s1 and s2" in its parameters, and inside the method, a loop is declared that checks the range of s1 value and use if block to match each sequence and use a print method that prints it values.
Outside the method, two string variables are declared that holds a string value that passes into the "match_sequence" method and calls it.

b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32
Answers
Answer:
The output of the program is:
2 4 8 16 32 64 End
Explanation:
See attachment for proper presentation of the program
The program uses recursion to determine its operations and outputs.
The function is defined as: myMathFunction(int a, int r, int counter)
It initially gets the following as its input from the main method
a= 1; r = 2; counter = 0
Its operation goes thus:
val = a*r; 1 * 2 = 2
Print val; Prints 2
if (counter > 4) { System.out.print("End"); } : Not true
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 2; r = 2; counter = 1
val = a*r; 2 * 2 = 4
Print val; Prints 4
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 4; r = 2; counter = 2
val = a*r; 4 * 2 = 8
Print val; Prints 8
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 8; r = 2; counter = 3
val = a*r; 8 * 2 = 16
Print val; Prints 16
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 16; r = 2; counter = 4
val = a*r; 16 * 2 = 32
Print val; Prints 32
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 32; r = 2; counter = 5
val = a*r; 32 * 2 = 64
Print val; Prints 64
if (counter > 4) { System.out.print("End"); } : True
This prints "End"
So; the output of the program is:
2 4 8 16 32 64 End

Answers
Answer:

Explanation:

This same middle value is 2 but findMatch(array, mid + 1 high, key) is labeled twice to move the center pointer to its last position, that is, so move that search item's 'e.'

The effect when one part of a system changes C. The open-loop system becomes a closed-loop system.
Systemic change is generally understood to require adjustments or transformations in the policies, practices, power dynamics, social norms or mindsets that underlie the societal issue at stake. It often involves the collaboration of a diverse set of players and can take place on a local, national or global level.
How does a systemic change happen?All systems organize individual pieces into some sort of interrelated whole. Put simply, systemic change occurs when change reaches all or most parts of a system, thus affecting the general behavior of the entire system.
Why is systems change important?A systems-change approach is more appropriate for problems that are complex, unpredictable, and context-dependent. For example, the challenge of inadequate access to educational opportunities for children from low-income neighborhoods cannot be addressed with a straightforward, logistical fix.
