I know the following: [1] That the general form of conditional expression is: if * Boolean_expression* then *exp1* else *exp2 *[2] That a conditional expression must always have both a then and an elseexpression. [3] That both *exp1* and *exp2* must have the same type, which is the type of the entire conditional expression. [4] That *exp1* must be <true-value> and *exp2* must be <false-value> Reference: Discrete Mathematics Using Computer by John O'Donnell and et al. (Second Edition) My question: Is it possible that exp1 and exp 2 be different function calls of another functions (separately) elsewhere within the same program? Note: My Boolean_expression is Boolean My *exp1* is a function call elsewhere within the same program (more like a subroutine) My *exp2* is another function call also elsewhere within the same program.
