getting a address from the dos prompt and opening it

This is a pretty basic thing in C. If you take a look at any C book or even a web tutorial, this should be covered.
I assume by "address" you mean a file name. I'm not sure if this will help, but here's a short example that opens and closes a file:
/**** Untested (but if should be fine) ****/
#include <stdio.h>
#include <stdlib.h>
int main(int argc,char **argv)
{
FILE *fp;
if (argc<2) {
fprintf(stderr,"usage: %s <filename>\n",argv[0]);
return EXIT_FAILURE;
}
fp=fopen(argv[1],"r"
;
if (NULL!=fp) {
/* Do stuff with file */
fclose(fp);
} else {
fprintf(stderr,"Failed to open file %s\n",argv[1]);
return EXIT_FAILURE;
}
return 0;
}
If this isn't what you want, please clarify with another post.
