Q3. What does the cat say here ?
a) Says the number 4, for 1 second, 10 times and changes the value of number variable by multiplying previous value with 4.
b) Says the number 4, for 1 second, 10 times and changes the value of number variable by adding previous value with 4.
c) Says the number 4, and its multiples each for 1 second, till 40 and changes the value of number variable by multiplying previous value with 4.
