Arithmetic Operators
- Addition (+): Adds two values together
- Subtraction (-): Subtracts one value from another
- Division (/): Divides one value by another
- Multiplication (*): Multiplies two values together
- Exponentiation (^): Raises a number to a power
- Modulo (MOD): Returns the remainder of a division operation
- Integer Division (DIV): Returns the whole number of a division operation
Pseudocode example:
a ← 5
b ← 3
c ← a + b
d ← a - b
e ← a * b
f ← a / b
g ← a MOD b
h ← a ^ b
i ← a DIV b
Python example:
a = 5
b = 3
c = a + b
d = a - b
e = a * b
f = a / b
g = a % b
h = a ** b
i = a // b
Java example:
int a = 5;
int b = 3;
int c = a + b;
int d = a - b;
int e = a * b;
double f = (double) a / b;
int g = a % b;
double h = Math.pow(a, b);
int i = a / b;
Visual Basic example:
Dim a As Integer = 5
Dim b As Integer = 3
Dim c As Integer = a + b
Dim d As Integer = a - b
Dim e As Integer = a * b
Dim f As Double = a / b
Dim g As Integer = a Mod b
Dim h As Double = Math.Pow(a, b)
Dim i As Integer = a \ b
Logical Operators
- Equal to (=): Returns true if two values are equal
- Less than (<): Returns true if the first value is less than the second value
- Less than or equal to (<=): Returns true if the first value is less than or equal to the second value
- Greater than (>): Returns true if the first value is greater than the second value
- Greater than or equal to (>=): Returns true if the first value is greater than or equal to the second value
- Not equal to (<>): Returns true if two values are not equal
Pseudocode example:
a ← 5
b ← 3
c ← (a = b)
d ← (a < b)
e ← (a <= b)
f ← (a > b)
g ← (a >= b)
h ← (a <> b)
Python example:
a = 5
b = 3
c = (a == b)
d = (a < b)
e = (a <= b)
f = (a > b)
g = (a >= b)
h = (a != b)
Java example:
int a = 5;
int b = 3;
boolean c = (a == b);
boolean d = (a < b);
boolean e = (a <= b);
boolean f = (a > b);
boolean g = (a >= b);
boolean h = (a != b);
Visual Basic example:
Dim a As Integer = 5
Dim b As Integer = 3
Dim c As Boolean = (a = b)
Dim d As Boolean = (a < b)
Dim e As Boolean = (a <= b)
Dim f As Boolean = (a > b)
Dim g As Boolean = (a >= b)
Dim h As Boolean = (a <> b)
Boolean Operators
Boolean operators are logical operators that can be used to compare two or more values and return a Boolean value (True or False) based on the comparison. There are 3 you need to know:
- AND: Returns True if both conditions are True
- OR: Returns True if one or both conditions are True
- NOT: Returns the opposite of the condition (True if False, False if True)
Boolean Operators in Pseudocode:
IF (condition1 AND condition2) THEN
// code to execute if both conditions are True
END IF
IF (condition1 OR condition2) THEN
// code to execute if one or both conditions are True
END IF
IF NOT(condition) THEN
// code to execute if the condition is False
END IF
Boolean Operators in Python:
if condition1 and condition2:
# code to execute if both conditions are True
if condition1 or condition2:
# code to execute if one or both conditions are True
if not condition:
# code to execute if the condition is False
Boolean Operators in Java:
if (condition1 && condition2) {
// code to execute if both conditions are True
}
if (condition1 || condition2) {
// code to execute if one or both conditions are True
}
if (!condition) {
// code to execute if the condition is False
}
Boolean Operators in Visual Basic:
If condition1 And condition2 Then
' code to execute if both conditions are True
End If
If condition1 Or condition2 Then
' code to execute if one or both conditions are True
End If
If Not condition Then
' code to execute if the condition is False
End If
