Please help me to create an array which is coming from txt file...
Here is my code so far...
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
FILE *input; // declare a pointer of type FILE
char input_char; // a single character
#define width 15
#define height 40
char buffer[width][height]; // a buufer array
int n,m;
// ******** open
input=fopen("D:\\Documents and Settings\\wzq2gn\\My Documents\\Old pc\\Ferdy's File\\Lecture 3 Examples\\customer.txt","r");
for (n=0;n

And what exactly is the problem ??
Also, use the pre or code tags (just above the emoticons) when you post code. And don't forget to replace the < and > symbols in your code by the tags also (or you can select 'Ignore HTML tags')

Your code snippet would be that much more readable had you enclosed it within <pre> tags.
So what is the problem you are having?

It'd be much more efficient to at least use fgets(), rather than read one character at a time.
wzq2gn wrote: printf("%c,%c ",buffer[n][m]);
This tells printf() to print two characters, but you are only supplying one.

I need to use the fgetc for single character manipulation.
How do I get the contents of the array using printf?

Using fgetc() is very costly in terms of disk I/O. The fact that you need to do "single character manipulation" has nothing to do with using fgetc(). You could read the entire file into memory using one call to fread() and then operator on the character buffer.

printf() is used to print, not get. The format string governs how many variable arguments are passed to it. In your code snippet, you were only passing one, but two were required.

Do your requirements require a C-style implementation? That is, why not use the standard C++ libraries?

Your code was incomprehensible and you didn’t explain properly what you were trying to do so I took a guess. You should spend some more effort making you code intelligible, especially if you’re asking others to look at it. Anyway forget about old C functions such as “fgetc” and raw arrays. Here’s my program in C++:
----------------------
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
int main(int argc, char *argv[])
{
using namespace std;
// Open the input file.
ifstream iff("C:\\a.txt");
if (!iff)
{
cerr << "Failed to open input file!" << endl;
return 1;
}
// We'll store the file's contents in a 'vector' of 'string's.
typedef vector<string> FileContents_t;
FileContents_t fileContents;
// Read in the file line by line and add each line to 'fileContents'.
string line;
while (getline(iff, line))
{
fileContents.push_back(line);
}
// Now we can access any character in the file by its row and column.
unsigned int column = 5;
unsigned int row = 4;
if (row>=fileContents.size())
{
cerr << "Row out of range!" << endl;
return 1;
}
const string &ourRow = fileContents[row-1];
if (column>=ourRow.size())
{
cerr << "Column out of range!" << endl;
return 1;
}
char c = ourRow[column-1];
// Output the results.
cout << "Char at row " << row << " column " << column << " is " << c << endl;
return 0;
}
