question 2 Instructions: Question 2 consists of two subsections, Question 2.1 and Question 2.2. The code for both these subsections must be done as part of the Question 2 project. First do the code for Question 2.1 followed by the code for Question 2.2. Comment the Question 2.1 code in the main function while you are busy coding and testing the code for Question 2.2. Remember to uncomment all the code when you are done. Question 2.1 Given a positive integer, N, the ’3N+1’ sequence starting from N is defined as follows: If N is an even number, then divide N by two to get a new value for N If N is an odd number, then multiply N by 3 and add 1 to get a new value for N. Continue to generate numbers in this way until N becomes equal to 1 For example, starting from N = 3 the complete ’3N+1’ sequence would be: 3, 10, 5, 16, 8, 4, 2, 1 Write code to ask the user to enter a positive integer (N) in the main() function. Write a function sequence() that receives the integer value N and display the ‘3N+1’ sequence starting from the integer value that was received (entered by the user). The function must also count and return the numbers that the sequence consists of. The returned value must be displayed from the main() function. example input and output Enter a value for n: 3 3, 10, 5, 16 ,8, 4, 2, 1 number of items: 8 Another example input and output Enter a value for n: 10 10, 5, 16, 8, 4, 2, 1 number of items: 7
question 2
Instructions:
Question 2 consists of two subsections, Question 2.1 and Question 2.2. The code for both these
subsections must be done as part of the Question 2 project. First do the code for Question 2.1 followed by the code for Question 2.2.
Comment the Question 2.1 code in the main function while you are busy coding and testing the code
for Question 2.2.
Remember to uncomment all the code when you are done.
Question 2.1
Given a positive integer, N, the ’3N+1’ sequence starting from N is defined as follows:
If N is an even number, then divide N by two to get a new value for N
If N is an odd number, then multiply N by 3 and add 1 to get a new value for N.
Continue to generate numbers in this way until N becomes equal to 1
For example, starting from N = 3 the complete ’3N+1’ sequence would be:
3, 10, 5, 16, 8, 4, 2, 1
Write code to ask the user to enter a positive integer (N) in the main() function. Write a function sequence()
that receives the integer value N and display the ‘3N+1’ sequence starting from the integer value that was
received (entered by the user). The function must also count and return the numbers that the sequence
consists of. The returned value must be displayed from the main() function.
example input and output
Enter a value for n: 3
3, 10, 5, 16 ,8, 4, 2, 1
number of items: 8
Another example input and output
Enter a value for n: 10
10, 5, 16, 8, 4, 2, 1
number of items: 7
Question 2.2
NOTE: Pointers must be used to solve the following problem. You will 8 marks if pointers are not used, even if
the solution is correct.
Write a function createPassword() with no return value to randomly select 8 capital letters from the alphabet.
The function receives the address of the first characters of the password string as parameter.
Hint: Declare a characters string that contains all the capital letters of the alphabet and use the index values
of the characters in the string for random selection of characters,
e.g.
char alpha [27] = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”;
char *pAlpha = alpha;
Display the password from the main() function.
Write a function replaceVowels() with no return value to replace all the vowels (A, E, I, O, U) that have been
selected with a symbol from the list ($ % @ # &). That is, A must be replaced by $, E replaced by %, I must
be replaced by @, O replaced by #, and U must be replaced by &.
The function receives the address of the first characters of the password string as parameter.
Display the password agin from the main() function.
example output:
Random characters
WYYHBORI
vowels replaced
WYYHB#R@
