Real Life Example
Let’s think of a “real life example” where we need to find out if a person is old enough to vote.
In the example below, we use the >= comparison operator to find out if the age (25) is greater than OR equal to the voting age limit, which is set to 18:
Example
int myAge = 25;
int votingAge = 18;
printf("%d", myAge >= votingAge); // Returns 1 (true), meaning 25 year olds are allowed to vote!
Cool, right? An even better approach (since we are on a roll now), would be to wrap the code above in an if...else statement, so we can perform different actions depending on the result:
Example
Output “Old enough to vote!” if myAge is greater than or equal to 18. Otherwise output “Not old enough to vote.”:
int myAge = 25;
int votingAge = 18;
if (myAge >= votingAge) {
printf("Old enough to vote!");
} else {
printf("Not old enough to vote.");
}
