Assignment Operators
Code:Operator Example Is The Same As = x=y x=y += x+=y x=x+y -= x-=y x=x-y *= x*=y x=x*y /= x/=y x=x/y .= x.=y x=x.y %= x%=y x=x%y
Comparison Operators
Logical OperatorsCode:Operator Description Example == is equal to 5==8 returns false != is not equal 5!=8 returns true <> is not equal 5<>8 returns true > is greater than 5>8 returns false < is less than 5<8 returns true >= is greater than or equal to 5>=8 returns false <= is less than or equal to 5<=8 returns true
Code:Operator Description Example && and x=6 y=3 (x < 10 && y > 1) returns true || or x=6 y=3 (x==5 || y==5) returns false ! not x=6 y=3 !(x==y) returns true
