# Arduino - Comparison Operators

Assume variable A holds 10 and variable B holds 20 then −

Operator name Operator simple Description Example
equal to = = Checks if the value of two operands is equal or not, if yes then condition becomes true. (A == B) is not true
not equal to ! = Checks if the value of two operands is equal or not, if values are not equal then condition becomes true. (A != B) is true
less than < Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. (A < B) is true
greater than > Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. (A > B) is not true
less than or equal to < = Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. (A <= B) is true
greater than or equal to > = Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. (A >= B) is not true

## Example

```void loop () {
int a = 9,b = 4
bool c = false;
if(a == b)
c = true;
else
c = false;

if(a != b)
c = true;
else
c = false;

if(a < b)
c = true;
else
c = false;

if(a > b)
c = true;
else
c = false;

if(a <= b)
c = true;
else
c = false;

if(a >= b)
c = true;
else
c = false;
}
```

## Result

```c = false
c = true
c = false
c = true
c = false
c = false
```
