高二:最近研究的c语言的数个实例,很菜的哦

1:

#include "stdio.h" 
void main()
{
    printf("你好啊? 我靠!\n");
} 

2:

#include "stdio.h" 
void main()
{
    int a,b;
    a=485555;
    b=3825;
    printf("a=%d\n",a);
    printf("%d%d\n",a,b);
    printf("%d%8d\n",a,b);
} 

3:

#include "stdio.h" 
void main()
{
    int A,B,a,b;
    printf("输入一个数,然后按回车键");
    scanf("%d",&A);
    printf("输入一个数,然后按回车键");
    scanf("%d",&B);
    printf("先输入一个数,按空格键后,再输入第二个数,再按回车键");
    scanf("%d %d",&a,&b);
    printf("%d%8d\n",A,B);
    printf("%d%8d\n",a,b);
} 

4:

#include "stdio.h" 
#define RED 0
#define GREEN 1
#define BLUE 2
void main()
{
    int a=66;
    char c='A';
    double salary;
    char name[20]="张国强? 男? 28岁";
    salary=99.99;
    printf("%s\n",name);
    printf("工资 = %8.2f\n",salary);
    printf("\n%d,%x,%c\n",a,a,a);
    printf("%d,%x,%c\n\n",c,c,c);
    printf("红色%2d??? 绿色%2d??? 蓝色%2d\n",RED,GREEN,BLUE);
    printf("\n");
} 

5:

#include "stdio.h" 
#define RED 0
#define GREEN 1
#define BLUE 2 
void main()
{
    int a;
    char name[20]="张国强 男 28岁"; 
    a=sizeof(char);
    printf("size of char = %d\n",a);
    a=sizeof(int);
    printf("size of int = %d\n",a);
    a=sizeof(short int);
    printf("size of short int = %d\n",a);
    a=sizeof(float);
    printf("size of float = %d\n",a);
    a=sizeof(double);
    printf("size of double = %d\n",a); 
    a=sizeof RED;
    printf("\nsize of RED = %d\n",a);
    a=sizeof name;
    printf("size of \'name\' = %d\n",a);
    a=sizeof "file name";
    printf("size of \"file name\" = %d\n\n",a);
}

6:

#include "stdio.h" 
void main()
{
    printf("%d\n",'A');??? //字符A
    printf("%d\n",'\x41');? //字符A
    printf("\n%d\n",'\"');? //双引号
    printf("%d\n",'\'');?? //单引号
    printf("%d\n",'\\');?? //反斜线 
    printf("\n%d\n",'\a');? //响铃
    printf("%d\n",'\b');?? //退格
    printf("%d\n",'\t');??? //tab
    printf("%d\n",'\n');?? //回车换行
    printf("%d\n",'\v');?? //垂直制表
    printf("%d\n",'\f');?? //换页
    printf("%d\n\n",'\r');?? //回车
}

7:

#include "stdio.h" 
int a=66;
void main()
{
    int data[3] = {100,201,3300};
    static char str[ ]={'A','b',67,68,'\0'};
    auto char name[ ]="张国强 男 28岁";
    printf("%d,%d,%d\n",data[0],data[1],data[2]);
    printf("%s\n",str);
    printf("%s\n",name);
    printf("\n");
    a=sizeof data;
    printf("size of \'data\' = %d\n",a);
    a=sizeof str;
    printf("size of \'str\' = %d\n",a);
    a=sizeof name;
    printf("size of \'name\' = %d\n",a);
    printf("\n");
    printf("请输入你的身份证号码\n");
    gets(str);????????? //允许输入的数字间有空格
    printf("\n身份证号码: %s\n\n",str);
    puts(str); //和printf功能相同,
}

8:

#include "stdio.h" 
void main()
{
    double a,b,c;
    a=1155+112.3+11.4+20.5+10.2+5.2+10.1;
    b=a/110.3;
    c=2450*a;
    printf("\n总使用面积=%f 平方米",a);
    printf("利用率=%f %c\n\n",b*100,36);
    printf("售价=%f 元\n\n",c);
} 

就是这些了,才在研究所以都是一些简单的撒.
