How do I get the program to read a file line and input it as a string for username

Code Select Expand


int __cdecl BnBot::LogRead(char *lpszFmt, ...) {
   FILE *setup;
 va_list argptr;
 char szInStr[1024];
 va_start(argptr, lpszFmt);
 vsprintf(szInStr, lpszFmt, argptr);
 va_end(argptr);
 setup = fopen(lpszFmt, "st");

 if (!setup){
     printf("Unable to find file");
     return 0;
 }
 return 1;
}

Untested, uncompiled, etc:

Code Select Expand


FILE* SomeFile = fopen("TheFile.txt", "r");
if(!SomeFile){
 // couldn't open the file
}

char Username[16] = {0};
// Make sure the file isn't empty
if(!feof(SomeFile)){
 // Read the first line
 fgets((char*)&Username, 16, SomeFile);
}


Username now contains the first line of the file - or the first 16 bytes of it, whichever is shorter.

should get one less character, or make the array one longer, otherwise you're overwriting the null.

You might want to strip the newline off too - one easy way is with a strtok(line "\r\n") call after fgets.
