CPP conditions
Evaluation of Conditions
Any program is meant to do some actions based on conditions.
These conditions is normally based on an evaluation of expressions using Relational Operators which in C++ are:
Name | Operator | Sample | Evaluates to |
---|---|---|---|
Equals | == | 200/2 == 120*2 20*10 == 200 |
false true |
Not Equals | != | 200/2 != 120*2 20*10 != 200 |
true false |
Greater then | > | 200/2 > 120*2 20*20 > 200 |
false true |
Less then | < | 200/2 < 120*2 20*20 < 200 |
true false |
Greater then or equal to | >= | 200/2 >= 120*2 20*20 >= 200 |
false true |
Less then or equal to | <= | 200/2 <= 120*2 20*20 <= 200 |
true false |
Name | Operator | Sample | Description |
---|---|---|---|
AND | && | expession1 && expression2 | Both expressions must return true if the outcome shall be true |
OR | || | expession1 || expression2 | One of the expressions must return true if the outcome shall be true |
NOT | ! | !expression | If the expression return false the outcome will be true |
