Thread: input files in C

This is a simple question, but I don't use C often. I have a program which takes data from an input file, but I need to use C input funtions. I can either 1) redirect input at the command line (a.out < data.txt) or 2) have the user specity an input file at runtime.

I am currently using the first option, but my problem is that I use getch() to accept keyboard input later in the program. I do not know how to "unredirect" the input from the data file to the keyboard. I would actually like to use the 2nd option, but the only method I know to take input from a file is ifstream. I CANNOT use that. Can somebody help me out here?

I'm really glad I found this board...I was getting discouraged.

hi folk,

use the second option and here is the code for , only
if u did
not know
about it.....


int main(int argc,char **argv)
{
FILE *fp;

fp = fopen("your input file name", "r+");

{

/ /u'r input file content is stored in file pointer fp

//continue with what u want to do

}
fclose(fp);
}
