C++ readfromfile()

[DarthRaff]

Hello,

 

Happy new year every body!!!!

 

I'm want to load a level from a .dat file, but no succes. This is what i have:

 

 .
 .
 .
nivelActual = 1;
 .
 .
 .
void ReadFromFile()
{
FILE *fichDatos;
char nombreFich[50];
sprintf(nombreFich, "nivel%03d.dat", nivelActual);// This line is not working
fichDatos = fopen(nombreFich, "rt");
//fichDatos = fopen("nivel1.dat", "rt"); This works, so, the file exists
}
 .
 .
 .

 

Can someone tell me what am i doing wrong, please, thank you very much

Perhaps this

 

"nivel%03d.dat

 

shoudl be this:

 

"nivel%i.dat

Thank you very much, Aggror, it works

Although Aggror already answered the original question here is the reason, why your version didn't work.

Your original formatstring said "nivel%03d.dat". The "0" means fill with zeros to the left, so it would have meant "nivel001.dat".
