Exploring the C Else Statement: Conditional Code Execution

Understand the purpose of the else statement in C programming, which allows for conditional code execution when an if statement evaluates to false. Learn how to effectively implement else statements in your programs for improved logic flow.

C Else Statement

The else Statement

The else statement is used to specify a block of code to be executed if the condition in the if statement evaluates to false.

Syntax

if (condition) {
  // block of code to be executed if the condition is true
} else {
  // block of code to be executed if the condition is false
}

Example

int time = 20;
if (time < 18) {
    printf("Good day.");
} else {
    printf("Good evening.");
}

Good evening.

Example Explained

In the example above, the value of time is 20, which is greater than 18. This makes the condition in the if statement false, so the program moves to the else block and prints "Good evening."

If the value of time had been less than 18, the program would have printed "Good day."
