Array output empty

close being done this, output section coming blank.

the output (16 times) looks if input 1 1/3 4 fractions:

first fraction:  second fraction:  adding result: 1  multiplying result: 1

i'm not getting fractions input translate output, i'm not sure gap/mistake is

still missing first fraction , second fraction. adding , multiplication results correct, need show fractions being used.

basically want like:

console.writeline("first fraction: {0} {1}/{2} ",     fractionone.wholenumber, fractionone.numerator,      fractionone.denominator);  

however, depending on how have stored values in class members may
have parsing such as:

console.writeline("first fraction: {0} {1}/{2} ",     fractionone.numerator / fractionone.denominator,     fractionone.numerator % fractionone.denominator,     fractionone.denominator);
