**LOGICAL EXPRESSIONS :**

Generally, **Logical expressions** are those expressions that combines two or more expressions. Furthermore, for combining these expressions we use **logical operators**. Generally, Logical expressions return **0** for **FALSE** and on the other side, **1** for **TRUE**. These expressions include three types of operators that are as follows :

**AND Operator – &&****OR Operator – | |****NOT Operator – !**

*Some of the valid examples of Logical expressions are as follows :*

**(a > b) && (a > c)**

Here, the compiler will check both of the conditions. If both of the conditions are true, then the whole expression is **TRUE**. Furthermore, if one of the conditions become false, then the whole expression is **FALSE**.

**(m > 10) | | (n < 10)**

Here, the compiler will check both of the conditions. The difference is that if one of the conditions is true then the whole expression is **TRUE**. Furthermore, the expression will become **FALSE** only when both of the conditions are false.

**!(p==5)**

Here, if the value of the condition is true i.e. if “p==5”. Then the compiler negates the value of the condition i.e. the result becomes **FALSE**. Furthermore, if the value of the condition is false, then the result becomes **TRUE**.

#### RELATIONAL EXPRESSIONS :

**Relational expressions** are the expressions from which we can compare values of two expressions depending on the relationship between them. Generally, “*the expressions that contain relational operators are Relational expressions*.”

Furthermore, if the relation is **TRUE** then the value of relational expression is **1**. Also, if the relation is **FALSE** then the value of relational expression is **0**. These expressions include six types of operators that are as follows :

*Some of the valid examples of Relational expressions are as follows :*

**x > y****a >= b****c == d****p != q**

*Thus, it was all about C EXPRESSIONS.. Now, read on further for description on C STATEMENTS..*
