⑴ 编写程序，输入周一至周五中的任意一天，屏幕显示一条不同的短语，短语内容自拟。c语言
#include <stdio.h>
int main()
{
int day=0;
printf("输入星期几(要求输入1—7中的一个整数，例如星期六，输入 6)\n");
scanf("%d",&day);
switch(day)
{
case 1:printf("星期一快乐！");break;
case 2:printf("星期二快乐！");break;
case 3:printf("星期三快乐！");break;
case 4:printf("星期四快乐！");break;
case 5:printf("星期五快乐！");break;
case 6:printf("星期六快乐！");break;
case 7:printf("星期日快乐！");break;
default:printf("跟你说了要输入1—7中的一个整数");break;
}
printf("\n");
return 0;
}
⑵ 用c语言编程,各位大虾帮帮忙
#include<stdio.h>
void main()
{
int hour,week;
int money;
float tax;
printf("请输入星期与工作时间:");
scanf("%d%d",&hour,&week);
switch(week)
{
case 1:
money=20*hour;
break;
case 2:
money=20*hour;
break;
case 3:
money=20*hour;
break;
case 4:
money=20*hour;
break;
case 5:
money=20*hour;
break;
case 6:
money=20*hour*3;
break;
case 7:
money=20*hour*3;
break;
}
tax=(float)0.08*money;
printf("该日的税前工资为:%d\n",money);
printf("税金为:%.2f\n",tax);
}
⑶ c语言编写一个程序计算长途电话费。电话费根据以下费率计算： 1）周一到周五，上午八点到下午六点之间

⑷ 需要c语言大神啊，，，，例如，宿舍排值日表，宿舍6个人住，星期六星期日不算，星期一到星期五轮流排值
#include<stdio.h>
int main()
{
int i,m,n=1;
for(i=1;i<=40;i++)
{
printf("第%d周:\n",i);
for(m=1;m<=5;m++)
{
printf("星期%d：%d号床值日\n",m,n);
n++;
if(n==7)
n=1;
}
}
return 0;
}
//40周的安排
⑸ 急急！！用C语言编课程表，要求：每星期5天，每天不超过6节课，有语文、数学、英语、政治、历史、音乐
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#define DAYS_OF_A_WEEK 5
#define MAX_CLASSES_A_DAY 6
#define MAX_CLASS_NAME_LEN 10
#define TOTAL_CLASSESS_TYPE_NUM 5
typedef struct

};
char week_days_name[][10] ={"星期天","星期一","星期二","星期三","星期四","星期五","星期六"};
char class_arrange_table[MAX_CLASSES_A_DAY][DAYS_OF_A_WEEK][MAX_CLASS_NAME_LEN]={0};
int main(int argc, char *argv[])
{
int i,j,k;
int row,col;
srand(time(NULL));
for(i=0;i<TOTAL_CLASSESS_TYPE_NUM;i++)
{
for(j=0;j<class_data[i].class_num_per_week;j++)
{

while(strlen(class_arrange_table[row][col]) != 0)
{
row = rand()% DAYS_OF_A_WEEK ;
col = rand()% MAX_CLASSES_A_DAY;
}
strcpy(class_arrange_table[row][col],class_data[i].class_name);
}
}
printf("%4s","");
for(i=1;i<=DAYS_OF_A_WEEK;i++)
{
printf("|%10s",week_days_name[i]);
}
printf("\n");
for(i=0;i<MAX_CLASSES_A_DAY;i++)
{

printf("\n");
printf("%4d",i+1);
for(j=0;j<DAYS_OF_A_WEEK;j++)
{
printf("|%10s",class_arrange_table[i][j]);
}
printf("\n");
}
for(j=0;j<4+DAYS_OF_A_WEEK*10+DAYS_OF_A_WEEK;j++){ printf("-"); }
printf("\n");
return 0;
}
⑹ C语言编程输入数字1到7 分别输出周一到周日的英文单词
//这个就不用注释了吧
#include
"stdio.h"
void
main()
{
int
i;
printf("输入1~7其中一个数字：");
scanf("%d",&i);
switch(i)
{
case
1:
printf("Monday\n");break;
case
2:
printf("Tuesday\n");break;
case
3:
printf("Wednesday\n");break;
case
4:
printf("Thursday\n");break;
case
5:
printf("Friday\n");break;
case
6:
printf("Saturday\n");break;
case
7:
printf("Sunday\n");break;
default:
printf("April
Fools'
Day\n");break;
}
}
⑺ c语言输出字母星期一到星期日
#include<stdio.h>
enumweekday{
MON=1,TUE,WIN,THE,FRI,THI,SUN
};
intmain(intargc,char*argv[]){
inti;
charday[][3]="{MON},{TUE},{WIN},{THE},{FRI},{THI},{SUN}";
for(i=MON;i<=SUM,i++)
printf("%s ",day[MON-1][0]);
return0;
}
//不懂追问
⑻ C语言程序设计求助，求设计一个程序，要求输入1-7的整数，对应输出星期一~星期天，最好附上思路，谢谢
#include<stdio.h>void main()
{
int i;
printf("请输入1-7数字 ");
scanf("%d",&i);
switch(i)
{
case 1: printf("今天星期一");break;
case 2: printf("今天星期二");break;
case 3: printf("今天星期三");break;
case 4: printf("今天星期四");break;
case 5: printf("今天星期五");break;
case 6: printf("今天星期六");break;
case 7: printf("今天星期天");break;
}
}
switch语句应该学了吧 直接用switch语句进行选择就行了 运行结果：

10是换行字符'
'的ascii码。用scanf读取字符的时候，敲的回车回遗留在缓存里，下次再调用scanf读取字符时，会把这个'
'读出来，就不会再要求键盘输入了。
另外，每次输出后，又递归调用，这样随着输入次数的增加，递归会越来越深，很容易导致栈溢出。
