doubt in chellange question

Question

do{
int y=1;
System.out.print(y++ +" ");
}while(y<=10)

why the answer is code will not compile.

Answer 1

Run this.

int y=1;
do{

System.out.print(y++ +" ");
}while(y<=10);

1) int y was declared and initialized inside the do so it is accessible only inside the loop or it is local to the loop. While doesn't know what y is.

2) you are missing a ; at the end of while.

Answer 2

Data + string gives string in s.o.p() argument
