Introduction to Even-Odd Programs in C
Even odd programs in C are fundamental for beginners learning programming logic.
These programs efficiently determine whether a given number is even or odd, showcasing foundational concepts like conditional statements and operators in C.
Algorithm:
Input: Receive a number from the user.
Check: Use the modulo operator (%) to determine if the number is divisible by 2.
Condition: If the remainder is 0, the number is even; otherwise, it's odd.
Output: Display the result to the user.
Logic:
Even numbers are divisible by 2 with no remainder, while odd numbers, by contrast, leave a residue of 1 when divided by 2.
Example:
A simple C program prompts the user for input, checks if the number is even or odd, and then displays the result.
The logic involves using the modulo operator (%) to determine divisibility by 2.
The program then outputs the result to the user, confirming whether the number is even or odd.
// even odd program in C #include<stdio.h>int main() { int num; // Prompt user for input printf("Enter a number: "); scanf("%d", &num); // Check if number is even or odd if (num % 2 == 0) printf("%d is even.\n", num); else printf("%d is odd.\n", num); return 0; }
Output:
Enter a number: 3 3 is odd.
This program efficiently determines whether the entered number is even or odd and provides the result to the user for clarity and understanding.
