Write the values of r and s after the execution of the following code.

int p = 11, q = 21, r, s; 
r = ++q;
s = p++; 
r++;

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;
