C Exercises: Find the odd, even, positive and negative number form a given number and print a message

C Basic Declarations and Expressions: Exercise-110 with Solution

Classify a number as positive/negative and odd/even, or print "Zero"

Write a C program to find the odd, even, positive and negative numbers from a given number (integer) and print a message 'Number is positive odd' or 'Number is negative odd' or 'Number is positive even' or 'Number is negative even'. If the number is 0 print "Zero".

Sample Solution:

C Code:

#include <stdio.h>
int main () {
    int b;

    // Prompt the user to input a number (integer)
    printf("Input a number (integer):\n");

    // Read the input number
    scanf("%d", &b);

    // Check if the number is positive and even
    if ((b % 2 == 0) && b > 0){
        printf("Number is positive-even\n");
    }
    else{
        // Check if the number is negative and even
        if ((b % 2 == 0) && b < 0){
            printf("Number is negative-even'\n");
        }
        else{
            // Check if the number is positive and odd
            if ((b % 2 !=0) && b > 0){
                printf("Number is positive-odd\n");
            }
            else{
                // Check if the number is negative and odd
                if ((b % 2 != 0) && b < 0){
                    printf("Number is negative-odd\n");
                }
                else{
                    // If none of the above conditions are met, it must be zero
                    printf("Zero\n");    
                }
            }
        }
    }
}

Sample Output:

Input a number (integer):
12
Number is positive-even

Flowchart:

C programming Code Editor:

Previous: Write a C program to find and print the square of each even and odd values between 1 and a given number (4 < n < 101).
Next: Write a C program that accepts an integer from the user and divide all numbers between 1 and 100. Print those numbers where remainder value is 3.
