Challenge: Else Statement
Conditional statements allow you to control the flow of your program by making decisions based on certain conditions. In C, the else statement complements the if statement by specifying an alternative block of code to execute when the if condition is false.
if_else_syntax.c
12345if (condition) { // Statements to execute if condition is `true` } else { // Statements to execute if condition is `false` }
This structure is essential when you want your program to choose between two distinct paths based on a condition.
main.c
12345678910111213#include <stdio.h> int main() { int number = -7; if (number >= 0) { printf("The number is positive.\n"); } else { printf("The number is negative.\n"); } return 0; }
The else clause is always paired with an if statement and provides a clear alternative path for your program to follow when the condition in the if statement is not met. This helps make your decision-making logic more complete, ensuring that one of the two blocks will always be executed.

Write a function named is_adult that takes an integer parameter age.
- If
ageis 18 or above, the function should returntrue. - Otherwise, the function should return
false. - Use an
ifandelsestatement to implement the logic. - Do not print anything from the function.
