C Number Comparison Guide

In C language, comparing the size of two numbers can be achieved as follows:

1. Use the if statement:

#include <stdio.h>

int main() {
    int num1, num2;

    printf("请输入两个整数：\n");
    scanf("%d %d", &num1, &num2);

    if (num1 > num2) {
        printf("%d 大于 %d\n", num1, num2);
    } else if (num1 < num2) {
        printf("%d 小于 %d\n", num1, num2);
    } else {
        printf("%d 等于 %d\n", num1, num2);
    }

    return 0;
}

1. Using the ternary operator:

#include <stdio.h>

int main() {
    int num1, num2;

    printf("请输入两个整数：\n");
    scanf("%d %d", &num1, &num2);

    int max = (num1 > num2) ? num1 : num2;
    int min = (num1 < num2) ? num1 : num2;

    printf("最大值为：%d\n", max);
    printf("最小值为：%d\n", min);

    return 0;
}

Both of these methods can be used to compare the sizes of two numbers, so choose the appropriate method based on the specific situation.
