converting PCM to wav file

Question

#include 
#include 

int main() {

    FILE *fin,*fout;
    char buffer[1028];


    int readcount=0;
    short NumChannels = 1;
    short         


        

Answer 1

I know nothing about the file formats, but I find it hard to believe they would have a binary header followed by ascii data. So the use of fgets and fputs I find questionable since fgets looks for a \n terminator. So you could be losing data if the buffer fills up before it happens to find a \n ( 0xa ) byte.

while(!feof(fin))
{
    fgets(buffer,sizeof(buffer),fin);
    fputs(buffer,fout);
}

Something like this would make more sense

size_t n;
while((n = fread(buffer, 1, sizeof(buffer), fin)) > 0) {
   if(n != fwrite(buffer, 1, n, fout)) {
      perror("fwrite");
      exit(1);
   }
}
if(n < 0) {
   perror("fread");
   exit(1);
}

Also, why do you close fout and then reopen it?
