求一行行读文件,比较部分字符串的源代码.高分,顶都有~~~~~~~~~~~~~~

[eagleMX]

如题
分不够,再放

[wltsuj]

while( szBuffer[i] != '\n' && !feof(pfile) )
{
i++;
szBuffer[i] = fgetc(pfile);
}
szBuffer[i+1]=''\0';

[balas]

上面的函数如果读到'\n' 后那么就跳出了，只能读一行。
用CStdioFile 吧。
读一行ReadString( LPTSTR lpsz, UINT nMax );

[aimheliopause]

CStdioFile file("/*somefile*/");
CString strBuf;
while (file.ReadString(strBuf)) {
//do some compare
if (strBuf == _T("/*something*/"))
}

FILE *fp;
char temp[256];

if((fp=fopen(路径,"a+"))==NULL)
return;

while (!feof(fp))
{
memset(&temp,NULL,sizeof(temp));
fgets(temp,sizeof(temp),fp);
}
fclose(fp);

统计一个文本文件里一个特定字符串出现了多少次：

STL版：
程序：
#include <iostream>
#include <fstream>
#include <string>

using namespace std;
const std::string Key = "wo";

int main(int argc, char* argv[])
{
if (argc >= 2)
{
std::ifstream ifile(argv[1]);
if (ifile.is_open())
{
int n = 0;
std::string str;
while(ifile >> str)
{
for(int k=0; (k=str.find(Key,k))!=std::string::npos; k++)
{
n++;
}
}
std::cout << "关键字有 : " << n << std::endl;
}
}
else
{
std::cout << "No file for open !" << endl;
}
return 0;
}


测试文件：
wo, wo, wo, and to bo ok wwe wo
mm oo m wo wowo and wowowk wookwokwo.
wwo kkwo kkwkwkowo

搜索关键字： wo

输出：15

MFC 版
CFileDialog dlg(TRUE);
if (dlg.DoModal() == IDOK)
{
CString strFile = dlg.GetPathName();
CStdioFile file(strFile, CFile::modeRead);
CString strTxt;
CString strKey = "wo";
int n = 0;
while (file.ReadString(strTxt))
{
for(int k=0; (k=strTxt.Find(strKey, k))!=-1; k++)
{
n++;
}
}
TRACE("***** Wo Count : %d", n);
}

用CStdioFile的ReadString试一试吧，
读一行就处理一下！

[bzpscu]

FILE *fp;
char temp[256];

if((fp=fopen(路径,"a+"))==NULL)
return;

while (!feof(fp))
{
memset(&temp,NULL,sizeof(temp));
if (!fgets(temp,sizeof(temp),fp))
break;
}
fclose(fp);
