查找三個輸入數字中最大和最小的程序，並顯示識別出的最大/最小數字是偶數還是奇數

Question

這是我的作業，我對如何識別最小/最大數字是偶數還是奇數感到困惑。

#include <stdio.h>
void main()
{
    int num1,num2,num3;
    printf("Enter three numbers\n");
    scanf("%d %d %d",&num1,&num2,&num3);
    if(num1<num2 && num1<num3){
        printf("\n%d is the smallest",num1);
    }
    else if(num2<num3){
        printf("\n%d is the smallest",num2);
    }
    else{
        printf("\n%d is the smallest",num3);
    }
    if(num1>num2 && num1>num3){
        printf("\n%d is largest",num1);
    }
    else if(num2>num3){
        printf("\n%d is largest",num2);
    }
    else{
        printf("\n%d is largest",num3);
    }
    getch();
    return 0;
}

Answer 1

使用2個變量，一個存儲最小的，一個存儲最大的。

int min, max;

然后，分配變量：

if (num1 < num2)
    min = num1;
if (num3 < min)
    min = num3;
printf("%d is the largest number", min);

要知道一個數是奇數還是偶數，其除以 2 的余數（也稱為模數）將為 0（偶數）或 1（奇數）：

int modulo = min % 2;
if (modulo == 0)
    printf("%d is even", min);
else
    printf("%d is odd", min);

Answer 2

/*Write a program to find the largest and smallest among three entered numbers and
also display whether the identified largest/smallest number is even or odd*/
#include <stdio.h>
#include <conio.h>
void main()
{
    // start the programme
    int a, b, c, large, small;
    printf("Enter three numbers : \n");
    scanf("%d%d%d", &a, &b, &c);
    if (a > b && a > c)
    {
        printf("\n%d is largest", a);
        large = a;
    }
    else if (b > c)
    {
        printf("\n%d is largest", b);
        large = b;
    }
    else
    {
        printf("\n%d is largest", c);
        large = c;
    }
    if (a < b && a < c)
    {
        printf("\n%d is smallest", a);
        small = a;
    }
    else if (b < c)
    {
        printf("\n%d is smallest", b);
        small = b;
    }
    else
    {
        printf("\n%d is smallest", c);
        small = b;
    }
    if (large % 2 == 0)
    {
        printf("\n %d is even", large);
    }
    else
    {
        printf("\n %d is odd", large);
    }
    if (small % 2 == 0)
    {
        printf("\n %d is even", small);
    }
    else
    {
        printf("\n %d is odd", small);
    }
    getch();
    // end the programme
}
