Pankaj makes a program to print the product of cubes of the first 10 whole numbers.

She writes the following program:

integer x = 0 // statement 1

integer x = 0 // statement 1

integer sum = 0 // statement 2

while ( x < 10 ) // statement 3

{

sum = x*x*x // statement 4

x = x + 1 // statement 5

}

print sum // statement 6
