⑴ 編寫程序，輸入周一至周五中的任意一天，屏幕顯示一條不同的短語，短語內容自擬。c語言
#include <stdio.h>
int main()
{
int day=0;
printf("輸入星期幾(要求輸入1—7中的一個整數，例如星期六，輸入 6)\n");
scanf("%d",&day);
switch(day)
{
case 1:printf("星期一快樂！");break;
case 2:printf("星期二快樂！");break;
case 3:printf("星期三快樂！");break;
case 4:printf("星期四快樂！");break;
case 5:printf("星期五快樂！");break;
case 6:printf("星期六快樂！");break;
case 7:printf("星期日快樂！");break;
default:printf("跟你說了要輸入1—7中的一個整數");break;
}
printf("\n");
return 0;
}
⑵ 用c語言編程,各位大蝦幫幫忙
#include<stdio.h>
void main()
{
int hour,week;
int money;
float tax;
printf("請輸入星期與工作時間:");
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("該日的稅前工資為:%d\n",money);
printf("稅金為:%.2f\n",tax);
}
⑶ c語言編寫一個程序計算長途電話費。電話費根據以下費率計算： 1）周一到周五，上午八點到下午六點之間
#include <stdio.h>
int main()
{
char str[2];
int b,c,d,flag=0;
double e=0;
scanf("%s %d %d %d",&str,&b,&c,&d);
if((str[0]=='m' ||str[0]=='M') &&(str[1]=='O' ||str[1]=='o'))

}
⑷ 需要c語言大神啊，，，，例如，宿舍排值日表，宿舍6個人住，星期六星期日不算，星期一到星期五輪流排值
#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號床值日\n",m,n);
n++;
if(n==7)
n=1;
}
}
return 0;
}
//40周的安排
⑸ 急急！！用C語言編課程表，要求：每星期5天，每天不超過6節課，有語文、數學、英語、政治、歷史、音樂
#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

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));

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("%4d",i+1);
for(j=0;j<DAYS_OF_A_WEEK;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語言編程輸入數字1到7 分別輸出周一到周日的英文單詞
//這個就不用注釋了吧
#include
"stdio.h"
void
main()
{
int
i;
printf("輸入1~7其中一個數字：");
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語言輸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;
}
//不懂追問
⑻ C語言程序設計求助，求設計一個程序，要求輸入1-7的整數，對應輸出星期一~星期天，最好附上思路，謝謝
#include<stdio.h>void main()
{
int i;
printf("請輸入1-7數字 ");
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語句應該學了吧 直接用switch語句進行選擇就行了 運行結果：

10是換行字元'
'的ascii碼。用scanf讀取字元的時候，敲的回車回遺留在緩存里，下次再調用scanf讀取字元時，會把這個'
'讀出來，就不會再要求鍵盤輸入了。
另外，每次輸出後，又遞歸調用，這樣隨著輸入次數的增加，遞歸會越來越深，很容易導致棧溢出。
