a. return always has to have any number after it, it can't be 'void'. ex: return(0); or return(1); or even return(variable); if variable is stored as a number.
b. You can not use return as a variable, return can only be used to return a number back if the code ran successfully, use a different word. ex: int number; or int variable;
c. this is correct, but only if var_a is initialized as a number of any kind either by the user or defined earlier in the code. ex: int var_a=2; return var_a;
d. This is fine as well, as long as the variables used are defined. It will only return with the number of var_c though.
e. This is fine as well, as long as var_a and var_b are defined as numbers, it will return with the 2 variables added together.
f. This does not work, the return function has to return with a number. ex: return(1); or return(97);
g. This is ok. True will be shown as a 1 value and false will be shown as a 0 value.
h. This is fine. It will return with code 66 for some reason, but it works. note: only doing return('A') returns with code 65 for some reason.
