just declare a file pointer for eg FILE* f ,then





f=fopen("drive letter:\file1.txt","mode");





mode work


"a" append can make changes at the end of file


"r" read you can just read the file cant chang in this mode


"w" write you can write any where in your file

Use the below code as a reference......

void main( )


{


FILE *fp;


char c;


int i=1;


fp = fopen("TENLINES.TXT", "r"); // Open the file to be read





if (fp == NULL) printf("File doesn't exist\n");


else {





// perform the loop until EOF


while(!feof(fp)) {





// Read a single line.....


if(fgets(str, 126, fp)) {


printf("%s", str);


//createfile(" Call create file function from here....


................


..................








}





}











}


fclose(fp);


}








void createfile(char* filename,char* content)


{


FILE *fpwrite;





int index;


fpwrite = fopen(filename,"w"); /* open for writing */


strcpy(stuff,content);


for (index = 1; index %26lt;= 10; index++)


fprintf(fpwrite,"%s Line number %d\n", stuff, index);


fclose(fpwrite); /* close the file before ending program */


}

Compile errors in my header file? why? c++?

before in my header file i had this:


File Edit Options Buffers Tools C++ Help


#ifndef SWAP_H


#define SWAP_H


//#include %26lt;string%26gt;


//#include %26lt;iostream%26gt;


using namespace std;





void swap (string %26amp;, string %26amp;);





#endif


-------


that gave me these compile errors:


Swap.h:7: error: `string' was not declared in this scope


Swap.h:7: error: parse error before `,' token

now i have:


#ifndef SWAP_H


#define SWAP_H


//#include %26lt;string%26gt;


//#include %26lt;iostream%26gt;


using namespace std;





std::void swap (string %26amp;, string %26amp;);


#endif

Swap.h:7: error: `string' was not declared in this scope


Swap.h:7: error: parse error before `,' token

ALL this happens when i try to compile my Swap.cpp file.. help? wats wrong?

The compiler doesn't know what a "string" is.





uncomment the #include %26lt;string%26gt; and add


using std::string;

Binary Tree for searching file in c++?

I wanna write a c++ program to search inside a file and build a binary tree of all those words inside the file. Anyone can help or send me the code if you have ??





Thankx

Binary Tree for searching file in c++?
Here's some code in C, but it should compile just fine


under C++ (and you can "pretty it up" with C++ method


definitions to replace the C functions if you like):





http://nob.cs.ucdavis.edu/classes/ecs030...





Also, if your problem is no more sophisticated than what


you've described, you could read the words into an array


and call qsort() in probably 20 lines of code.

Fully qualify your path names (not doc.txt, but C:\Documents and Settings\Administrator\My Documents\doc.txt). This guarantees that a "file not found" is a file that doesn't exist there.





An unsafe way around getting rid of those ERROR: Must use C++ is including (before the libraries) a #define __cplusplus line. That should work, considering that the safety responsible for that mechanism is:


#ifndef __cplusplus


#error Must use C++


#endif

What are the file read & write functions in C# ???

Actually i want to know that what are the file read %26amp; write functions in C#, like fputs(),fgets(), or fprintf(), and fscanf(); and please also mention how to open file in c# . and how to close it.......





please reply............

What are the file read %26amp; write functions in C# ???
Ok, what you're describing is C functions which the concept is expanded in C#. Several objects are used to read and write files. They include the buffered streams, file streams, text read/writers to name a few. Most fall under the system.io class or input/output class of structure. An example is demonstrated below:





using System;


using System.IO;





class FSRead


{


public static void Main()


{


//Create a file stream from an existing file.


FileInfo fi=new FileInfo("c:\\csc.txt");


FileStream fs=fi.OpenRead();





//Read 100 bytes into an array from the specified file.


int nBytes=100;


byte[] ByteArray=new byte[nBytes];


int nBytesRead=fs.Read(ByteArray, 0, nBytes);


Console.WriteLine("{0} bytes have been read from the specified file.", nBytesRead.ToString());


}


}








I've also included some links below.





Hope this helps.
