Need help with this C program please!
For this task, you will complete bit_ops.c by implementing the following three bit manipulation batch functions. You will want to use bitwise operations such as and (&), or (|), xor (^), not (~), left shifts (<<), and right shifts (>>).
#include <stdio.h>
#include <stdlib.h>
// Note, the bits are counted from right to left.
// Return the bit states of x within range of [start, end], in which both are inclusive.
// Assume 0 <= start & end <= 31
unsigned * get_bits(unsigned x,
unsigned start,
unsigned end) {
return NULL;
// YOUR CODE HERE
// Returning NULL is a placeholder
// get_bits dynamically allocates an array a and set a[i] = 1 when (i+start)-th bit
// of x is 1, otherwise siet a[i] = 0;
// At last, get_bits returns the address of the array.
}
// Set the bits of x within range of [start, end], in which both are inclusive
// Assume 0 <= start & end <= 31
void set_bits(unsigned * x,
unsigned start,
unsigned end,
unsigned *v) {
// YOUR CODE HERE
// No return value
// v points to an array of at least (end-start+1) unsigned integers.
// if v[i] == 0, then set (i+start)-th bit of x zero, otherwise, set (i+start)-th bit of x one.
}
// Flip the bits of x within range [start, end], in which both are inclusive.
// Assume 0 <= start & end <= 31
void flip_bits(unsigned * x,
unsigned start,
unsigned end) {
// YOUR CODE HERE
}

- In the following C program, identify what is wrong with code and correct it. This program reads addresses from an input.txt file and sorts the adresses by order of zip codes into an output.txt file. Please also see the following error codes, thank you main.c: #include "contacts.h"#include <stdio.h>#include <stdlib.h> int main(int argc, char **argv) {size_t size;FILE *fp_in, *fp_out;errno_t err; if (argc != 3) {printf("Usage: %s infile outfile", argv[0]);return 0;} err = fopen_s(&fp_in, argv[1], "r");if (err != 0) {perror("Failed opening file for reading");}err = fopen_s(&fp_out, argv[2], "w+");if (err != 0) {perror("Failed opening file for writing");} contact **c = alloc_contacts(MAX_CONTACTS);size = get_contacts(c, fp_in);if (size == 0)perror("get_contacts failed");sort_contacts(c, size);print_contacts(c, size, fp_out);free_alloc(c, size); if (fp_in) {err = fclose(fp_in);if (err != 0) {perror("File could not be closed");}} if (fp_out) {err = fclose(fp_out);if…// Task 2 NEED HELP WITH C programming // For this function, you must build a string that when printed,// will output the entire binary representation of the integer x,// no matter how many bits an integer is.

This function returns the largest of the two values. If these are equal, it returns their sum.
- In c++, please. Thank you! Given a main() that reads user IDs (until -1), complete the BubbleSort() functions to sort the IDs in ascending order using the Bubblesort algorithm, and output the sorted IDs one per line. You may assume there will be no more than 100 user IDs. Ex. If the input is: kaylasimms julia myron1994 kaylajones -1 the output is: julia kaylajones kaylasimms myron1994 The following code is given: #include <string>#include <iostream> using namespace std; // TODO: Write the Bubblesort algorithm that sorts the array of string, with k elementsvoid Bubblesort(string userIDs [ ], int k) { } int main() { string userIDList[100]; string userID; cin >> userID; while (userID != "-1") { //put userID in the array cin >> userID; } // Initial call to quicksort Bubblesort(userIDList, /* ?? */ ); //make this output only the userIDs that were entered, not garbage for (int i = 0; i < 100; ++i) { cout <<…This exercise is to write a Decimal to Hex function using BYTE operations. You can use a List, Dictionary or Tuple for your Hex_Map as shown below, but it's not necessary to use one. It is necessary to use Byte operations to convert the decimal to hex. The bitwise operations are also available as __dunders__. Write a function to convert a integer to hexidecimal. Do not use the Python hex function (i.e. hexnumber = hex(number)) to convert the number, instead write your own unique version (i.e. MYHEX: hexnumber = MYHEX(number)). Your function should not use any Python functions like hex, dec, oct, bin or any other Python functions or modules. Functions, like Python ORD, can be used to convert a string to a integer. The input number range is 0 to 1024. def MYHEX(number): hex_map = {10: 'A', 11: 'B', 12: 'C', 13: 'D', 14: 'E', 15: 'F'} result = '' while number: digit = number % 16 if digit > 9: result = hex_map[digit] + result else:…PROGRAM IN PLAIN C PLEASE! Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
- When a variable is stored in memory, it is associated with an address. To obtain the address of avariable, the & operator can be used. For example, &a gets the memory address of variable a.Let's try some examples.Write a C program addressOfScalar.c by inserting the code below in the main function. 1 // intialize a char variable, print its address and the next address2 char charvar = 'a';3 printf("address of charvar = %p\n", (void *)(&charvar));4 printf("address of charvar - 1 = %p\n", (void *)(&charvar - 1));5 printf("address of charvar + 1 = %p\n", (void *)(&charvar + 1));67 // intialize an int variable, print its address and the next address8 double doublevar = 1.0;9 printf("address of doublevar = %p\n", (void *)(&doublevar));10 printf("address of doublevar - 1 = %p\n", (void *)(&doublevar - 1));11 printf("address of doublevar + 1 = %p\n", (void *)(&doublevar + 1)); Questions:1) Run the C program, attach a screenshot of the output in the answer…Computer Science Write a C++ language program that reads the file numbers.txt having 10,000 random integers ranging from 1-1,000,000. It takes an input argument num_jobs with a value between 1 and 8. E.g. if num_jobs is 3, it splits into 3 parallel processes using fork() function and each process then calculates prime numbers from a subset of the input data. Together these 3 jobs find prime numbers from all the 10,000 input integers. The overall parent process then combines the results from its children into a single file prime.txt. NOTE: The key part is to solve it with fork()Computer Science Write a C program that calls malloc() 1001 times allocating blocks of size 4 each. Use type char * to store the pointers returned by malloc(). When done, print the difference in the addresses of the first and last block allocated. This difference is the amount of memory malloc actually used to create 1000 blocks of size 4. It is a lot more than you would expect. Repeat this for other block sizes and make a table of your results. Do you see any pattern? Any guesses why?

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 chunkI need the code in C programing i am begging you please. There are several test cases. Each test case begins with a line containing a single integer n (1≤n≤1000). Each of the next n lines is either a type-1 command, or an integer 2 followed by an integer x. This means that executing the type-2 command returned the element x. The value of x is always a positive integer not larger than 100. Given a sequence of operations with return values, you’re going to guess the data structure. It is a stack (Last-In, First-Out), a queue (First-In, First-Out), a priority-queue (Always take out larger elements first), not sure(It can be more than one of the three data structures mentioned above) or impossible(It can’t be a stack, a queue or a priority queue).
