❸ 如何做C語言課程設計

想偷懶的話就寫一個控制台程序......

完全不需要圖形化的函數什麼的.......

工程,文件操作這些都沒什麼實。

我這邊有一套不錯的C語言課程設計,如果你喜歡可以拿去直接用,我還沒有在網上放過。

❹ C語言課程設計

(C語言)職工信息管理
有任何問題可以到這里留言:

http://moonrosa.googlepages.com/liuyan.htm

【要求】
職工信息包括職工號,姓名,性別,年齡,學歷,工資,住址,電話等(職工號不相等)。試設計一職工信息管理系統,使之能夠提供下列功能:
(1)系統以菜單方式工作
(2)職工信息錄入功能(職工信息用文件保存)
(3)職工信息瀏覽功能
(4)職工信息查詢功能,查詢方式:
1)按學歷查詢
2)按職工號查詢
(5)職工信息刪除,修改功能(可選項)。

❻ C語言課程設計 簡單的.....

Answer To Question 1 & 2 :

充分利用ISO組織於1999年通過的C語言國際標准中的庫函數即可實現第一題。利用簡單的雙重循環即可解決問題二,用遞歸演算法不是好的選擇。

第一題完整源碼:
(注意:本源碼中,函數GetWeekDay的返回值僅僅表示輸入參數是否「正確/有效」(例如前三個參數使用2001,2,29就是無效參數),能否得到預期的星期值;真正的星期值則是通過輸出變數返回給主調函數的。)
////////////////////////////////////////////
#include <time.h>
#include <stdio.h>

int GetWeekDay(int nYear,int nMon,int nDay, int *npWeekDay);

int main()
{
int nMyWeekDay;
int nResult;

nResult = GetWeekDay(2007,1,10,&nMyWeekDay);

return 0;
}

//輸入日期,返回星期的C語言函數
int GetWeekDay(int nYear,int nMon,int nDay, int *npWeekDay)
{
int nRetVal = 0;
time_t tMyDateTime;
struct tm tmMyDate,*tmpMyDate;

if((nYear<1900||nYear>=3000)
|| (nMon<1 || nMon>12)
|| (nDay<1||nDay>31) )
{
nRetVal = 1;
*npWeekDay = -1;
return nRetVal;
}
//memset(tmMyDate,0,sizeof(struct tm));
tmMyDate.tm_year = nYear-1900;
tmMyDate.tm_mon = nMon-1;
tmMyDate.tm_mday = nDay;
tmMyDate.tm_hour =16;
tmMyDate.tm_min =30;
tmMyDate.tm_sec =30;

tMyDateTime = mktime(&tmMyDate);
if(tMyDateTime<0)
{
nRetVal = 1;
*npWeekDay = -1;
return nRetVal;
}
tmpMyDate = localtime(&tMyDateTime);
*npWeekDay = tmpMyDate->tm_wday;
return nRetVal;
}
//Over

////////////////////////////////////////////////////
第二題:
#include <time.h>
#include <stdio.h>

int Sum(int n, int a);

int main()
{

//出題者可以自己將此處改為要求操作人鍵入N/A的值
int n=5,a=2,s;

s = Sum(n,a);

return 0;
}

//解決問題的函數
int Sum(int n, int a)
{
int nSum =0;
int nTmp;
int i,j;

for(i=1;i<=n; i++)
{
nTmp =a;
for(j=1;j<=i;j++)
{
nTmp += a*10*(j-1);
}
nSum += nTmp;
}
return nSum;
}

❼ C 課程設計

#include<iostream>

#include<iomanip.h>

#include<math.h>

usingnamespacestd;

intmain()

{

doublesample[6]={6.22,5.46,4.70,3.85,2.48,0.70},ym[6],r[6];

doubleb0,b1,b2,b3;

intflag,i;

b0=sample[0];

for(b2=-10;b2<10;b2+=0.01)

for(b3=-10;b3<10;b3+=0.01)

{

flag=1;

b1=sample[1]-b0-b2-b3;

for(i=2;i<6;i++)

if(fabs(b1-((sample[i]-b0)/i-b2*i-b3*i*i))>0.025)

{flag=0;break;}

if(flag)

{

cout<<"b0=6.22,b1="<<b1<<",b2="<<b2<<",b3="<<b3<<endl;

cout<<"------------------------------ ";

cout<<"xyymr% ";

cout<<"------------------------------ ";

for(i=0;i<6;i++)

{

ym[i]=b0+b1*i+b2*i*i+b3*i*i*i;

r[i]=fabs(ym[i]-sample[i])/sample[i]*100;

cout<<setw(2)<<i<<setw(6)<<sample[i];

cout<<setw(7)<<ym[i]<<setw(7)<<setprecision(2)<<r[i]<<endl;

}

cout<<"------------------------------ ";

return0;

}

}

return0;
