## 第一题 ##

![c758b47dccb947ad90ff45b3eb407289.png][]

**代码：**

#include <stdio.h>
    
    int main()
    {
        //%md m就是控制域宽的长度
        printf("%15d\n", 0xABCDEF);
        return 0;
    }

## 第二题 ##

![8988ac99d8ff4bf5bf5a30ee55cc58c5.png][]

**代码：**

#include <stdio.h>
    
    int main()
    {
        //%d 打印有符号十进制整数
        //%0 打印无符号八进制整数
        //%x 打印无符号小写的十六进制整数
        //%X 打印无符号大写的十六进制整数
        // #的作用是显示前缀，对o 输出时加上前缀0
        // 对x 输出时加上前缀0x 对X 输出时加上前缀0X
    
        //方法一 直接加
        //printf("0%o 0X%X\n", 1234, 1234);
        //方法二 用#显示前缀
        printf("%#o %#X\n", 1234, 1234);
        return 0;
    }

## 第三题 ##

![b0aded7c4b684a63a26d063ca73d7f77.png][]

**代码：**

#include <stdio.h>
    
    int main()
    {
        char ch = 0;
        int a = 0;
        float b = 0;
        //因为要用换行符隔开，我们就加上\n
        scanf("%c\n%d\n%f", &ch, &a, &b);
        //要求保留6位小数，我们就用%.6f
        printf("%c %d %.6f\n", ch, a, b);
        return 0;
    }

## 第四题 ##

![7424b5a97e9949999c95ef79e3e33b9d.png][]

**代码：**

#include <stdio.h>
    
    int main()
    {
        int a = 0;
        int b = 0;
        int c = 0;
        scanf("%d %d %d", &a, &b, &c);
        // 后面两个数要占8个空格的宽度
        // %md就是栈的域宽有m个的空格长度 所以用%8d
        printf("%d%8d%8d\n", a, b, c);
        return 0;
    }

## 第五题 ##

![1e0ac1e309d840fca907b90fd531b946.png][]

**代码：**

#include <stdio.h>
    
    int main()
    {
        int a = 0;
        int b = 0;
        //%x 表示十六进制 %o表示八进制
        scanf("%X %o", &a, &b);
        //%的表示10进制 直接相加就可以
        printf("%d\n", a+b);
        return 0;
    }

## 第六题 ##

![2cce6b8e3554421e8c0df37b2d2856b8.png][]

#include <stdio.h>
    
    int main()
    {
        int a = 0;
        int b = 0;
        scanf("%d%d", &a, &b);
        //将a+b的值赋给C
        int c = a + b;
        //打印结果
        printf("%d\n", c);
        return 0;
    }

## 第七题 ##

    int main()
    {
        int a = 0;
        int b = 0;
        //输入两个数
        scanf("%d%d", &a, &b);
        //将a/b的数放到c中  /：只取整数部分
        int c = a/b;
        //将结果打印出来
        printf("%d\n", c);
        return 0;
    }

## 第八题 ##

![8edfdd6ec73548f2a10d8d817811410e.png][]

        int b = 0;
        scanf("%d%d", &a, &b);
        //% 取模： 
        int c = a%b;
        printf("%d\n", c);
        return 0;
    }

    {
        float a = 0.0f;
        scanf("%f", &a);

        //将浮点数a强制类型转换为整型b b保留的就是a的整数部分
        int c = b%10;
        //在通过取模把个位上的数给c
        printf("%d\n", c);
        return 0;
    }
