Write a C language function named count that takes a void pointer and int parameter, representing a memory buffer, and a uint8_t parameter representing a byte, and returns an int result. The returned result should be the number of occurrences of the byte in the bufer. For example if the buffer p pointed to the bytes 01 12 01 23, then count(p, 4, 0x01) should return 2.

- Write a C program that uses the following: a main() to read two integer values from the user, val1 and val2, and prints the returned value from swap().a swap() that uses call by reference (takes the addresses into pointers) to swap values, and prints their values after the swap "num1 = # and num2 = #". This function returns the largest of the two values. If these are equal, it returns their sum.Write a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit...

- In C, write a function that gets 3 pointers int* a, int* b, int* c, and rotates the values in their addresses to the left. That is, a gets the value of b, b gets the value of c, and c gets the value of a. void rotate3 (int* a, int* b, int* c); For example, if we have int x=1, y=2, z=3, then after calling rotate3 (&x, &y, &z) we should have x==2, y==3, and z==1. if we have int x=7, y=1, z=6, then after calling rotate3 (&x, &y, &z) we should have x==1, y==6, and z==7.Write a function f which takes three pointers to int variables (a, b, c). Then it should:-Set the first variable to the sum of values of the variables (a + b + c).-Set the second variable to difference between maximum and minimum of values ( max(a,b,c) - min(a,b,c) )-Set the third variable to median of a, b, c.For example:if a = 5, b = 10, c = 2Then f(&a, &b, &c) should:Set a to 17 (that is the sum)Set b to 8 (that is max - min = 10 - 2)Set c to 5 (that is the median of 5, 10 and 2) NOTE: You are already provided a test main which checks your code for evaluation. DO NOT MODIFY IT or your answer will NOT be accepted. #include<stdio.h> // Write your code here... //////////////////////////////////////////// THIS IS THE TEST MAIN FOR YOUR PROGRAM// DO NOT MODIFY IT!!int main() {int a = 1;int b = 2;int c = 3;for (int i = 0; i < 2; i++) {f(&a, &b, &c);printf("%d\n", a);printf("%d\n", b);printf("%d\n", c);}return 0;}//////////////////////////////////////////…Write a function in C++ called maximumGap that finds the maximum difference between corresponding entries in two arrays (that have the same capacity). There are 3 parameters, the 2 arrays and their capacity. If the arrays store 9, 0, 3 and 4, 7, 6 the maximum gap is 7 (between the second elements of the two arrays).
- Write a program to find the number of times that a given word occurs in a sentence using pointers. Read data from standard input. The first line is a single word, which is followed by general text on the second line. Read both up to a new line character, and insert a terminating null before processing. Typically output should be : The word is “ the ”. The sentence is “ the cat on the mat “ . The word occurs 2 times.

Ali#F#01102020#05101970#COVID-19#AlBireh#A-In C In C, strings are implemented by a contiguous sequence of characters, terminated by NUL character, otherwise known as ASCII code 0 (10'). CAPI, provides a function stropy for copying strings. The prototype of the function is given in the following: char* strepy(char* destination, const char* source); A) Write your own version of stropy that receives two character pointers and copies the source string into the destination string, character by character, until it reaches a null character. • The function stops when it reaches the end of the string, in which case it makes sure the destination string is properly terminated. • The function returns the original destination pointer as its return value. • The function assumes that source and destination strings are valid pointers. • In case either source or destination pointers are NULL, the function simply returns NULL. B) Write a small program that demonstrates the use of your version of strepy() function. • Define a character array and…
