CodePudding user response:
if ((fp=fopen (" Fname ", "r"))==NULL) {/* open data file */ This sentence has a problem, to:
if ((fp=fopen (Fname, "r"))==NULL) {/* open data file */ You write the code, is to open the file named Fname file, not the filename you input, because the variables Fname deposit is the file path string;
CodePudding user response:
But still won't do, in fact, I copied the file path, then the Debug an Assertion Failed, big trouble you again, thank youCodePudding user response:
