1. declare integer product declare integer number product =0 do while product < 100 display “enter number” input number product = number*10
2. do{ sum =0 print(“enter=a”) read a print(“enter=b”) read b sum = a*b print(“sum=”+sum) print(‘ do you wish to continue”) read Response
} while (RESPONSE)

Do { while x > 0 display “enter a number” input x
} End while
