For the randchar function shown in this code, the return statement sends back the value of character r. The variable itself isn't returned. Variable r is local or private to the randchar function, but its value is sent back to the main function where a loop outputs the value seven times. The goal is to generate a random word, and today's random word is XQCARWF. Well, that's how I'd pronounce it. The randchar function generates a random value from zero to 25 at line nine. The value of character A is added to the value in variable r at line 10, which produces an uppercase letter of the alphabet. Then the value of variable r is returned. The parentheses here are optional, unless the expression you're returning requires them. Functions in C cannot return more than a single value. Two options for getting around this limitation are using pointers as arguments and…
