The fopen function in Codeblocks does not support the command "R"

Codeblocks

#include <stdio.h>

#include <stdlib.h>

void Main (void)

{

FILE *fp=null;

if ((fp=fopen ("Shuju.txt", "R")) ==null)

{

printf ("Can not open the file! \ n ");

Exit (0);

}

Fclose (FP);

return (0);

}

Run this program, always print out "Can not open the file!", in various forums and Baidu a bit, no fruit.

Constantly useless to try, the "R" is rewritten as "r+", the problem of unreadable files can be resolved.

Finally, the problem is solved, but why is the "R" Operation not supported in the Codeblocks programming environment? The same statement is compiled under vc6.0 and can read the file normally.
