Design and implement a simple shell program to read a command with a file redirection. here we use the following file-redirection symbols as follow: "in=infile" for input file named "infile", "out=outfile" for output file named "outfile", "app=appfile" for output to be appended a file named "appfile". for example, "ls out=out. txt" will output the result of the command to a file named out. txt. name your program: a2prog2.cbase code for shell: /* world's simplest shell – shell0.c */#include#include#include#include# include#include#include#includevoid sig_int(int signo) { printf("\ncaught sigint! \n"); }char* getinput(char *linefer, size_t linelen) { printf("myshell > "); return fgets(linefer, linelen, stdin); }

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
