- 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:Make a program in C language of the following: 1. Make a tic-tac-toe game using 2D array. Please do the above using the most simplest and efficient way possible. No use of Pointers Please.Python Coding Exercise: Write a function that takes three parameters: a 2-D array arr, a row location i, a column location j and returns a float representing the fraction of neighbors around arr [i,j] # write your function here:def find_frac(arr,i,j):
- In C programming: Write a function printAllCourses() which receives an array of course pointers and the array’s size, then prints all courses in the array by calling printCourseRow()using c++ Define an array of n integer marks and fill it with random numbers, send it to a function that returns an array of failed marks. Hint: use pointer notations onlyPointer arithmetic. Implement the following:a. Implement a print function with array and size parameters. This function should print the array using pointer arithmetic.b. Overload the print function to accept array, size and index parameters. If the index is between 1 and size-2 inclusive: Use pointer arithmetic to print: 1. the value at index 2. the value previous to the index 3. the value after the index c. Implement a sum function with array and size parameters. This function should return sum of the array, and use pointer arithmetic.d. Implement a average function with array and size parameters. This function shouldreturn average of the array, and use pointer arithmetic.e. Use provided main function to test your functions. ( Do not change the int main the question has provided. Included a snip of the int main function. Output has to be the same as shown in the snips)
- please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]Questlon 1: Write a C program that do the following: write a recursive function that receives a character pointer and replace each 'a' with 'u'. • in the main function define a character array and ask the user to input a word and save it in the array. Call the function. Print the array. Sample input/output: Please enter a word: Safaa After replace: SufuuDefine the term " pointer print array " .
- Use pointers to add two arrayProgram in C language (Please solve part 2) Part one : Write a program that does the following: Creates int array array_1 of length 10. Creates int array array_2 of length 10. Takes int values from the user of for 10 values for array_1 and array_2, each. Creates a new int array array_3 which copies the values of array_1 and array_2, in interleaved order, into it. Prints out the contents of Prints out the contents of array_1, array_2 and array_3. Part two : Repeat Part one, but this time use arrays of char (instead of int), and stop receiving input into array_1 and array_2 when the user hits Enter / newline and insert a Null character into the arrayC program Andrew practices programming a lot and recently he came across the topic of pointers. He wondered if he could use pointers to print all prime numbers from an array? Could you help him by writing a C program which takes input in an array and uses a pointer to find and print all the prime numbers from the array. Sample Run: Input: 1 2 3 4 5 Output: 2 3 5
