This is from the 2016 marking scheme...(Q7) How has variable 'i' been used in the second method too? Isn't a local variable? And couldn't we just have declared it before void SumSeries(int n, double x)??? import java.util.*; class Q7 { void SumSeries(int n, double x) { double sum=0.0d; int i; for(i=1;i<=n;i++) { if (i%2==0 ) sum=sum-x/(double)i; else sum=sum+x/(double)i; } System.out.println("sum="+sum); } void SumSeries() { int s=0, p=1; for(int i=1;i<=20;i++) { p=p*i; s=s+p; } System.out.println("sum="+s); } public static void main(String args[]) { Q7 obj=new Q7(); obj.SumSeries(5,2.0); obj.SumSeries(); }}} |

If y = 10, what is the value of : ++y * (y++ + 5) I think it should be 15 * 12 = 180 but I am getting 176 as the output. Any reason why it does prefix before parentheses when parentheses are above prefix in precedence? |
