Question

Consider the following if statement, where doesSignificantWork, makesBreakthrough, and nobelPrizeCandidate are all boolean variables: if doesSignificantWork : if makesBreakthrough : nobelPrizeCandidate = True else nobelPrizeCandidate = False elif not doesSignificantWork: nobelPrizeCandidate = False (assume that doesSignificantWork and makesBreakthrough have been initialized, there is no error) First, write a simpler if statement that is equivalent to this one. Then write a single assignment statement that does the same thing. (Hint: Try to trace this piece of code with all possible initial values for makesBreakthrough and doesSignificantWork. It helps you to understand the code and then you can simplify it and rewrite it).

Answer 1

Firstly, if else equivalent:

if(doesSignificantWork) {

if(makesBreakthrough) {

noblePrizeCandidate=true; }

else {

nobelPrizeCandidate=false; }

}

else if( ! doesSignificantWork) {

noblePrizeCandidate=false; }

Now coming to single statement we can use ternary operators in below format:

For eg : variable = condition ? expression1 : expression2;

Using above format

noblePrizeCandidate= doesSignificantWork ? ( makesBreakThrough ? true : false) : false ;
