- How to check whether a number is odd or even without using if else statement in one line.
- Write a program in C to check a number is odd or even.
Algorithm to check odd and even number using bitwise operator
- Check whether least significant bit of a number(N) is 0 or not by doing bitwise And(&) with 1. if (N & 1) == 0, that means N is even otherwise odd number.
C program to check odd or even number using bitwise operator
#include<stdio.h>
int main() {
int n;
printf("Enter a number\n");
scanf("%d", &n);
(n & 1 && printf("Odd"))|| printf("Even");
return 0;
}
Output
Enter a number 3 3 is Odd
Enter a number 12 12 is Even
C program to check odd or even number using bitwise operator
Algorithm to check odd and even number using bitwise operator
- If input number(N) is divisible by 2(N%2 == 0) then N is even otherwise odd number.
#include<stdio.h>
int main() {
int n;
char *strList[] = {"Even", "Odd"};
printf("Enter a number\n");
scanf("%d", &n);
printf("%d is %s", n, strList[n%2]);
return 0;
}
Output
Enter a number 5 5 is Odd
Enter a number 8 8 is Even
