How to open a file (text file) from a specific location using C?

[animeprogrammer]

Hello fellow programmers, i'm having trouble opening a file from a specific location. Please help.

#include "maidcafe.h"
....
char directory[80] = {"C:\\Users\\Public\\Documents\\Anime Notes\\Transaction\\"};
char code[20];
printf("Enter file name");
gets(code);
strcat(directory,code);
system("start \"\" %s",directory);
 
 

i thought this would work, but it didn't xD. I got an error

Usually a file is opened using fopen.

FILE* fp;
fp = fopen("C:\\etc...", "w+");

If you're wanting some external program to use your file, then IIRC, system doesn't like the extra quotes and whatnot, so build your command string before calling the function. Use the short path name (the 8.3 notation) or you might try adding quotes around the entire finished path.

char directory[255] = "start \"c:\\......\\";
// make sure directory has enough space
 
// get your file name
 
strcat(directory, code);
strcat(directory, "\"");
 
system(directory);
 

Another alternative is to use sprintf

char cmd[255] = { 0 },
     directory[80] = "c:\\.....\\",
     code[20] = { 0 };
 
// get required info
 
sprintf(cmd, "start \"%s%s\"", directory, code);
system(cmd);
