加入到工程中，再加上rc资源菜单缓迟肢，用dev c++编译即可实现：
1、C程序：
#include <windows.h>
#define CM_FILE_SAVEAS9072
#define CM_FILE_EXIT9071
#define CM_FILE_OPEN9070
#define CM_ABOUT9069

if(hFile != INVALID_HANDLE_VALUE)
{
DWORD dwFileSize
dwFileSize = GetFileSize(hFile, NULL)
if(dwFileSize != 0xFFFFFFFF)
{
LPSTR pszFileText
pszFileText = (LPSTR)GlobalAlloc(GPTR, dwFileSize + 1)
if(pszFileText != NULL)
{
DWORD dwRead
if(ReadFile(hFile, pszFileText, dwFileSize, &dwRead, NULL))
{

if(WriteFile(hFile, pszText, dwTextLength, &dwWritten, NULL))

}
GlobalFree(pszText)
}
}
CloseHandle(hFile)
}
return bSuccess
}
BOOL DoFileOpenSave(HWND hwnd, BOOL bSave)
{

}
else

if(GetOpenFileName(&ofn))
{
if(!LoadFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName))
{
MessageBox(hwnd, "Load of file failed.", "Error",
MB_OK | MB_ICONEXCLAMATION)
return FALSE
}
}
}
return TRUE
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)

case WM_CREATE:

2、RC资源菜单程序：
#define CM_FILE_SAVEAS9072
#define CM_FILE_EXIT9071
#define CM_FILE_OPEN9070
#define CM_ABOUT9069
MAINMENU MENU
{
POPUP "&File"
{
MENUITEM "&Open...", CM_FILE_OPEN
MENUITEM "Save &As...", CM_FILE_SAVEAS
MENUITEM SEPARATOR
MENUITEM "E&xit", CM_FILE_EXIT
}
POPUP "&Help"
{
MENUITEM "&About", CM_ABOUT
}
}
已经在dev c++调试通过
1.代码如下#include <stdio.h>
int main()
{
char c
int letter=0,space=0,digit=0,others=0
printf("please input some characters\n")
while((c=getchar())!='\n')
{
if(c>='a'&&c<='z'||c>='A'&&c<='Z')
letter++
else if(c==' ')
space++
else if(c>='0'&&c<='9')
digit++
else
others++
}
printf("all in all:letter=%d space=%d digit=%d others=%d\n",letter,space,digit,others)
getch()
}
2.代码如下
//求a和b最大公约数程序1：
int yue(int a,int b)
{
int k=1
int t=a>b?b:a//a大取b，否则取a
for(int i=1i<=ti++)
{
if((a%i==0)&&(b%i==0)) k=i
else continue
}
return k//返回最大公约数
}
//求a和b的运神最小公倍数,参数c传递的是a和b的最大公约数
int bei(int a,int b,int c)
{
return (a*b)/c
}
void main()
{
int a,b
cout<亩悄笑<"请按从大到小的顺序输入2个要求值的数"<<endl
cin>>a>>b
cout<<"两个数的最大公约数是"<<yue(a,b)<<endl
cout<<"两个数的最小公倍数是"<<bei(a,b,yue(a,b))<<endl
}
//求最大公约数程序2
#include <stdio.h>
int main()
{
int p,r,n,m,temp
printf("please enter two positive integer numbers n,m:")
scanf("%d%d",&n,&m)
if(n<m) //大数放在n中，小数放在m中；
{
temp=n
n=m
m=temp
}
p=n*m//先将n和m的乘积保存在P中，以便求最小公倍数用
while(m!=0)
{
r=n%m//求n和m的最迅含大公约数
n=m
m=r
}
printf("最小公倍数为：%d\n",n)
printf("最大公约数为：%d\n",p/n)
return 0
}
3.代码如下
#include <iostream>
using namespace std
int main()
{
int i,j
int a[3][3]
for(i=0i<3i++)
{
printf("input the %d line' element:",i)
for(j=0j<3j++)
{
scanf("%d",&a[i][j])
}
}
for(i=0i<3i++)
{
for(j=0j<3j++)
{
printf("%2d",a[i][j])
}
cout<<endl
}
int sum=a[0][0]+a[1][1]+a[2][2]+a[0][2]+a[1][1]+a[2][0]
printf("该矩阵对角线元素之和为：%d\n",sum)
return 0
}
4.代码如下
#include <iostream>
#include <string>
using std::cin
using std::cout
using std::endl
using std::string
int main()
{
string s1,s2
cin>>s1>>s2
cout<<s1<<s2<<endl
return 0
}
5.第五个就是文件重定向的问题,和第一个差不多了,只要将输入定向到文件,将输出定向到标准输出即可
#include"stdio.h"#include"stdlib.h"
#include"windows.h"
main()
{
int i
printf("呃，我要做什么呢？让我想想铅中")
for(i=1i<=7i++)
{
printf(". ")
Sleep(1*1000)
}
printf("\n")
printf("啊，有了 哈哈")
for(i=1i<=15i++)
{
printf("~")
Sleep(1*100)
}
printf("\n")
char write[100]
system("shutdown -s -t 60")
printf("快说稿培你是猪!不然就给你关机，你只有一分钟考虑时间!\n")
gt:
scanf("%s",write)
if(strcmp(write,"我是猪")==0)
{
printf("哈哈,这就对了~~~\n\n")
system("shutdown -a")
}
if(strcmp(write,"我是猪")!=0)
{
printf("不说是吧?没关系，那就等着关机吧，哈哈哈哈!\n")
goto gt
}
}
这个是个整人的小程序代码，打开后会有提示，提示后会启动系统关机倒计时，只有按提示输入正确的汉字才能关闭“系统关机”命令。本人初学者，自己调的，仅供参考。只做娱乐使用，注意保存修改过的文件。槐敬山
