I have a TXT file with contents named test.txt as follow: This is a test 444444 333333 good by! I defined a ifstream variable named inFile and intialized with a string "test.txt", and I defined string outString and an ofstream variable named outFile with "output.txt" for initializing.I used the statements for coping the content of file test.txt into file output.txt as follow: inFile >;>; outStri...
Dear all: I am going to read a file "data.dat", its content is: [Code] 5 0 2 3 5 2 4 2 4 2 4 3 100 1 3 4 2 3 2 2 3 4 2 200 2 3 5 3 5 4 4 2 4 3 300 2 3 5 2 4 2 4 2 4 2 400 2 3 5 2 3 2 4 2 4 2 500 1 3 5 2 4 2 4 2 3 2 [/code] I want to sepearate the data into three part. The first one is [code] N=5; [/code] The second one is [code] key=[0 2 3 5 2 4 2 4 2 4 ...
c++中 ifstream infile(file.txt)中，file.txt的默认路径是什么？ EOF,EOL 文件结束符，行结束符分别是什么？

[code] class doctmpl { ............... //声明 protected: char varflag; istream& is; ifstream ifs; ............... }; //这个函数正确 inline doctmpl::doctmpl(const string& fname, char chvar /* = '$' */) : ifs(fname.c_str()), is(ifs), varflag(chvar) { if ( !ifs.is_open() ) throw e_stream_err; } //open函数通不过 inline void doctmpl::open(const string& fname, char chvar) { ifs.open(fname.c_s...
First declare that this is a vc++ programming.
Target:Accomplish the function of the copy in which from ofile.txt to tonney.txt file.
Main implementation function: getline().
Coding as follow:
//首先,实现从ofile.txt读取content,并把content保存到vector中去，return这个vector指针
void *CTestForTemplateOneDlg::OnGetStringLine()
{
UpdateData();
