void wordSwapper(char *source, char *destination) { // This function takes a pointer to a 'source' string (an array // of chars, with maximum size MAX_STR_LEN), and // makes a new string inside the 'destination' string // (which is also passed as a pointer) so that the order // of the words in the destination string is the reverse // of the order in the source string. // // e.g. if: // The 'surce' string contains "Hello I Am A String!" // // then the destination string will contain // // 'String! A Am I Hello" // (notice that we add a space between each word in the // destination string - these are *added*, not *copied*) // // The only character to be used in separating words is // a blank space, so any other characters are considered // part of a word, for example "Hello, I; Am! A. *String*" // will becoe "*String* A. Am! I; Hello," // // You *MUST* use pointers and pointer addressing to complete // this exercise (that is, no array notation with brackets []), // and you can not assume the 'destination' string is empty, // it could (and likely does) contain junk. // // If you decide to write helper functions, make sure they // are placed *above* this function's code. // TO DO: Complete this function }
