In C++ Create an array of head pointers, statically allocated of size 101 of that type: Now, create a pointer that can point to the first element: Show how to dynamically allocate an array of 101 elements of head pointers: Write the code to initialize each element to NULL: Rewrite the code to initialize each element to NULL using pointer arithmetic:
a. Given the variables valuesArray and arrayPtr defined below, assign the variable arravPtr to the valuesArray and do pointer arithmetic to print out (using a cout statement) each element of valuesArray. int valuesArray[3] = {66, 23, 92}; int *arrayPtrị b. The address of valuesArrav[0] is Ox7ffc125d3e20. What is the address of these elements of the array? valuesArray[1] address is: valuesArray[2] address is: ww m me
Create a program and flowchart for the following: Write a program that uses random-number generation to create sentences. The program should use four arrays of pointers to char called article, noun, verb and preposition. The program should create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article and noun. As each word is picked, it should be concatenated to the previous words in an array large enough to hold the entire sentence. The words should be separated by spaces. When the final sentence is output, it should start with a capital letter and end with a period. The program should generate 20 such sentences. The arrays should be filled as follows: The article array should contain the articles "the", "a", "one", "some" and "any"; the noun array should contain the nouns "boy", "girl", "dog", "town" and "car"; the verb array should contain the verbs "drove", "jumped", "ran", "walked" and "skipped"; the preposition…

Character arrays and pointers in C: I have to search and sort through an EXTREMELY large text file in C using standard libraries. How do I import the text file and then access any character in the file using pointers? I need to be able to access multiple different characters at different positions in the file at once, so using the fgetc() function doesn't help as I can only access 1 character at a time in that order that it is read. The text file is way too big to create an empty char array and store each character and access them that way, so I'm not sure what else I can do. Thanks in advanced
Write a function to sort strings in dictionary order. Example: Giving 'C programming', 'Java', 'CIS-1007', 'University'. The output in dictionary order should be: "C programming" "CIS-1007" "Java" "University" Note: You might ask the user to give the number of the input strings. You might need to use multidimensional arrays to store these strings. Note: You are NOT ALLOWED to use any built-in library EXCEPT stdio.h.
Write a c function that swaps the first and the last elements of chunks in an array. For an array consisting of 9 elements and assuming a chunk of size 3: Array elements: 1 2 3 4 5 6 7 8 9 The output would be, 3 2 1 6 5 4 9 8 7 Inverting here means swapping the last and the first element of a chunk. Note: Size of array should always be multiple of chunk size. User will enter the size of array and chunk
