bookChallenge: If Statement

Scorri per mostrare il menu

You have already explored the importance of control flow in programming. Now, it is time to focus on the basic building block of decision-making in C: the if statement. The if statement allows you to execute a block of code only when a specific condition is true. Its syntax is straightforward:

main.c

main.c

copy

              
123

            
if (condition) {
    // Statements to execute if condition is true
}

Here, the condition is an expression that evaluates to either true (non-zero) or false (zero). If the condition is true, the code inside the braces runs; otherwise, it is skipped.

main.c

main.c

copy

              
123456789101112

            
#include <stdio.h>

int main()
{
    int age = 20;

    // User is an adult
    if (age >= 18)
        printf("Access granted.\n");

    return 0;
}

This simple structure enables your programs to make decisions and respond differently to various inputs or situations.

Swipe to start coding

Write a function that uses an if statement to check if a given integer is positive. If the number is greater than zero, return a value indicating that it is positive.

  • Use an if statement to test if number is greater than zero.
  • If true, return a value (such as 1) to indicate the number is positive.
  • Otherwise, return a value (such as 0) to indicate the number is not positive.
