#include <windows.h>
#include <stdio.h>
char cmdstr[256];
int i;
int YN(int k) {
FILE *f;
char fn[40];
char ln[80];
int yn=0;
sprintf(fn,"d:\\ping%d.txt",k);
f=fopen(fn,"r");
if (NULL!=f) {
fgets(ln,80,f);
fgets(ln,80,f);
fgets(ln,80,f);
if (1==fscanf(f,"Re%c",&yn)) yn='q'-yn;
fclose(f);
unlink(fn);
}
return yn;
}
void main() {
for (i=115;i<130;i++) {
sprintf(cmdstr,"cmd /c ping 192.168.2.%d -n 1 -w 1000 >d:\\ping%d.txt",i,i);
WinExec(cmdstr,SW_HIDE);
}
Sleep(3000);
for (i=115;i<130;i++) {
printf("%d 192.168.2.%d\n",YN(i),i);
}
}
