assuming libraries are included how many times will sentence print out?
Expert's answer
int height = 5
while(height<8) //5<8 true
{
print("the statement evaluted totrue!");//first time
height+1; //height = 6
}

while(height<8) //6<8 true
{
print("the statement evaluted totrue!");//second time
height+1; //height = 7
}

while(height<8) //7<8 true
{
print("the statement evaluted totrue!");//third time
height+1; //height = 8
}

while(height<8) //8<8 false
END
