The function should accept three arguments:the name of a file, a pointer to an int array, and the size of the array. The functionshould open the specified file in binary mode, write the contents of the array to the file,and then close the file.Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. Thefunction should open the specified file in binary mode, read its contents into the array,and then close the file.Write a complete program that demonstrates these functions by using the arrayToFilefunction to write an array to a file, and then using the fileToArray function to readthe data from the same file. After the data are read from the file into the array, displaythe array’s contents on the screen.arrow_forwardTo write an object to a file, you use the ________ function of the ________ module.arrow_forward
