LINUX C Programming Lists IP segment.
One idea:
Some scanners may need to provide IP lists. This can be used as an input to the IP file by some scanners, and now you can write the program to provide these IPs.
Second function description.
Where the selection function Switch. Loop function for check the related function description. Not explained here!
Three writing procedures:
Creating a file: Nightcat @ nightcat $ vi showip.c
Edit the following:
/*SHOWIP.C Version 1.0
* The Tools Show IP Include A B And C Class's IP
* You can see the tips for entering.

Main ()
{
Int Chioce, I, J, K, A, B, C;
File * fp;
Printf ("Please Enter Your Chioce, / N Enter 1 Chioce a Class./n Enter 2 Chiose B Class. / N Enter 3 Chiose C Class: / N");
Scanf ("% D", & chioc);
Switch (chioc) {
Case 1: Printf ("Enter A as 211 ENTER / '-1 /' TO End / N"); Scanf ("% D", & A); IF (A == - 1) {
Break;
} IF ((FP = FOPEN ("Listipa.txt", "W ")) == null) {Printf ("cann't open files./n"); exit (1);} for (i = 1; i <= 254; i ) {for (j = 1; j <= 255; j ) {for (k = 1; k <= 255; k ) fprintf (fp, "% d.% d.% d.% D / N ", A, I, J, K);}} fclose (fp); Break; Case 2: Printf (" Enter B AS 211.239 ENTER / '- 1 /' TO End / N "); scanf (" % D.% D ", & A, & B); if (a == - 1) {Break;} IF ((fp = fopen (" Listipb.txt "," W ")) == null) {Printf (" Cann't open files / n "); exit (1);} for (i = 1; i <= 255; i ) {for (j = 1; j <= 255; j ) {fprintf (fp, "% d.% d.% D% .d / n", a, b, i, j);}} fclose (fp); Break;
Case 3: Printf ("Enter C AS 211.239.151 ENTER / '- 1 /' TO End / N"); Scanf ("% D.% d.% d", & a, & b, & c); if (a = = -1) {Break;} IF ((fp = fopen ("Listipc.txt", "W "))) == null) {Printf ("cann't open files / n"); exit (1);} For (i = 1; i <= 255; i ) {fprintf (fp, "% d.% d.% d.% d / n", a, b, c, i);} fclose (fp); Break }}
Save exit:
: WQ
Compilation execution: Nightcat @ nightcat $ gcc -o showip showip.cnightcat@nightcat $./show
I'm later:
This program is very simple. Mainly in the selection function Switch, and loop functions for.
There is also the read and write function of the file. FOPEN, FPRINTF.FCLOSE.
