C programming not C++

a) Crate a file homework_part_1.c

b) Crate a function initialize_array that receives two parameters: an array of integers and the array size. (Use pointers to pass an array of integers as parameter) Use a for loop and an if statement to put 5s in the odd positions of the array and 0s in the even positions.

c) Crate a function print_array that receives as parameters an array of integers and the array size. (Use pointers to pass an array of integers as parameter) Use a for statements to print all the elements in the array.

d) Crate a function selection_sort that receives as parameters an array of integers and the array size and order the array element in descending order. (Use pointers to pass an array of integers as parameter) Implement Selection Sort algorithm. It should be Selection Sort, not Bubble Sort, not Quick Sort, etc.

e) Crate a recursive function that calculate and returns the factorial of a number. The function receives the number (integer number) as parameter.

f) Copy the following main function in your class,

int main() {

int a [10] = {3, 5, 6, 8, 12, 13, 16, 17, 18, 20};

int b [6]= {18, 16, 19, 3 ,14, 6};

int c [5]= {5, 2, 4, 3, 1};

// testing initialize_array

print_array(a, 10); // print: 3, 5, 6, 8, 12, 13, 16, 17, 18, 20

selection_sort(a, 10);

print_array(a, 10); // print: 0, 5, 0, 5, 0, 5, 0, 5, 0, 5

// testing initialize_array

print_array(b, 6); // print: 18, 16, 19, 3 ,14, 6

selection_sort (b, 6);

print_array(b, 6); // print: 19, 18, 16, 14, 6, 3

// testing factorial

printf("Factorail of 5 - %d ", factorial (5)); //print: 120

c[0] = factorial (c[0]);

c[1] = factorial (c[2]);

print_array(c, 5); // print: 120, 24, 4, 3, 1

return 0;
