Go Conditions

Go Conditions

Conditions help in decision making. A condition is either true or false.

Go supports the usual comparison operators from mathematics:

• Less than x < y
• Less than or equal x <= y
• Greater than x > y
• Greater than or equal x >= y
• Equal to x == y
• Not equal to x != y

Additionally, Go supports the usual logical operators:

• Logical AND x && y
• Logical OR x || y
• Logical NOT !x

You can use these operators or their combinations to create conditions for different decisions.

Go has the following conditional statements:

• Use if to specify a block of code to be executed, if a specified condition is true
• Use else to specify a block of code to be executed, if the same condition is false
• Use else if to specify a new condition to test, if the first condition is false
• Use switch to specify many alternative blocks of code to be executed
• Use select is similar to switch but is used for channel communication.
