(take input from user) calculate the size of a given file in kbs. in this task you will complete the function with the following prototype: float get_file_size(char * filename); the function takes the file name (address to the start of a null terminated character array) as input. the function should then open the file and find the number of bytes it contains till eof. the number of bytes divided by 1024 will give the size in kbs. if the file cannot be opened the function should return -1.
