C Else Statement

C else statement

Created By: chatGPT

C programming provides the else statement as part of its control flow structure, which allows you to execute a block of code when the condition in the if statement is false. The else statement is often paired with an if to handle alternative scenarios in your program. Here’s a simple demonstration of how to use the else statement.

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

Consider the following example where we check a number to determine if it's positive or negative.

#include <stdio.h>

int main() {
    int number;
    
    printf("Enter a number: ");
    scanf("%d", &number);
    
    if (number > 0) {
        printf("The number is positive.\n");
    } else {
        printf("The number is negative or zero.\n");
    }
    
    return 0;
}

In this code snippet, we first prompt the user to enter a number and then check if that number is greater than zero. If it is, a message confirming that the number is positive is printed. If the condition is not met, the else statement executes, indicating that the number is either negative or zero.

// Sample Output:
// Enter a number: 5
// The number is positive.

// Enter a number: -3
// The number is negative or zero.
