Programming

The idea is:
Parent process: read each character from input file.. then write each of them to pipe
Child Process: read each character from pipe.. then encrypt it.. then write each of them to outputfile..


Void doParent()
{
if(fin!=NULL)
{
char c[2];
c[0]=fgetc(fin) // Get first charater from inputfile


while(c[0]!=EOF)
{
write(fd[1],c,2); // write to pipe
c[0]=fgetc(fin); // get each character from inputfile
};



fclose(fin); // close file
}
}



void DoChild()
{
char c[2];
read(fd[0],c,2); //


while(c[0]!=EOF)
{
char kitu=ceasarEncrypt(c[0]); // Encrypt each character

fputc((char ) kitu,fout); // put each encrypted character to outputfile..
read(fd[0],c,2);
};
fclose(fout);

}
