Write a C function with the following prototype: int copyFile(char *filenamel, char *filename2); Given the names of a destination and of a source file (respectively, filename1 and filename2), the function should copy the content of the source into the destination file, after transforming the alphabetic characters from lowercase to uppercase and vice- versa (all the other characters are copied as they are). In case the copy operation is not successful, the function should return he value -1. Otherwise, it should return the total number of characters that were successfully copied.
