Observe the following code and find that how many times will the loop execute?

int sum = 0, score = 0;
double t;
do
{
    score = score + 1; 
    sum = sum + score;
} while(score <= 3);
t = sum / 3;

Rewrite the following code using for loop.

int i = 1; 
int d = 5; 
do
{
    d = d * 2;
    System.out.println(d); 
    i++;
} while(i <= 5);

Name the operators listed below.

1. ?:
2. &&
3. <=
4. ++
