Question

How do I answer this question ?

Consider the following code snippet .
1) int i = 10
2) int n = i++%5

Question a: what are the values of i and n after the code is executed .

Question b: what are the final values of i and n if instead of using the postfix increment operator (i++), you use the prefix version (++i)?

I want to know how I start and which language to use to develop .

Answer 1

n = i++%5 = 10%5 =0, i++=>i=i+1=10+1=11
n=0,i=11

n = ++i%5, i++=>i=i+1=10+1=11,
n= 11%5 = 1
n=1,i=11
