Hello everyone.
i tried to write a program to eliminate nos from a file:
this is what i mean:
001 #include <QApplication>
002 #include <QPushButton>
003 int main(int argc, char *argv[])
004 {
005 QApplication app(argc, argv);
006 QPushButton *button = new QPushButton("Quit");
007 QObject::connect(button, SIGNAL(clicked()),
008 &app, SLOT(quit()));
009 button->show();
010 return app.exec();
011 }
this is the code in a book..i needed to elimiate those nos..i tried this program:
#include <stdio.h>
int main(void)
{
FILE *Numbered, *Filtered;
char fname[100];
int c;
printf("\nEnter the filename");
scanf("%s", fname);
Numbered = fopen(fname, "r");
Filtered = fopen("FILTERED.txt", "w");
while( (c = fgetc(Numbered)) != EOF ) {
if(c == '\n') {
putchar(c);// Put a \n
//fputc(c, Filtered);
if((c = fgetc(Numbered)) == EOF)
return 0;
while( c >= '0' && c <= '9' ) {
c = fgetc(Numbered);
}
}
putchar(c);
//fputc(c, Filtered);
}
fclose(Numbered);
fclose(Filtered);
return 0;
}
Its working,but going into an infinite loop! i mean its initially eliminating the nos. but getting into an infinite loop..
Can anyone please explain?
Thanks in advance.
