Q1. Write a program in C to find the given number is odd or even.

#include<stdio.h>
int main(){
          int n;
          printf("Enter the number:");
          scanf("%d",&n);
          if (n%2==0){
                printf("%d is a even number",n);
          }
          else{
                printf("%d is a odd number",n);
          }
          return 0;
}

Output

Enter the number:4

Q2. Write a program in C to find the greater number between two numbers.

Solution

#include<stdio.h>
int main(){
       int a,b;
       printf("Enter the number a:");
       scanf("%d",&a);
       printf("Enter the number b:");
       scanf("%d",&b);
       
       if(a>b){
            printf("%d is the greater number",a);
       }else if(b>a){
            printf("%d is the greater number",b);
       }else{
            printf("%d and %d is equal.",a,b);
       }
       return 0;
}Ot

Q3. Write a program in C to find whether the given number is Armstrong or not.

#include <stdio.h>
#include <math.h>
 int main() {
    int n, n1, temp, count = 0, rem;
    int arm = 0;
    printf("Enter the number: ");
    scanf("%d", &n);
    temp = n;
    n1 = n;
    while (n != 0) {
        n /= 10;
        count++;
    }
    while (n1 != 0) {
        rem = n1 % 10;
        arm += pow(rem, count);
        n1 /= 10;
    }
    if (arm == temp) {
        printf("The given number is an Armstrong number\n");
    } else {
        printf("The given number is not an Armstrong number\n");
    }
    return 0;
}

Output
Enter the number: 153
The given number is an Armstrong number
