How to block a number ?

If your mobile phone is lost or stolen you can inform your cell phone provider with your IMEI number. Your cell phone provider can then put the serial number on a shared database. This list stops this particular phone from registering on any network and will be useless for anyone even if the mobile phone's SIM card is changed.
Your best bet is to ring your cell phone and hope the person who answers your cell phone will return your phone to you. If your cell phone is GPS enabled then it is possible to track, but you need to contact your cell phone service provider. Otherwise I suggest you contact your cell phone provider ASAP.

A Personal Unblocking Code (PUC) or Personal Unblocking Key (PUK) is used in GSM mobile phones and some smartcards to unblock a blocked card.

Most mobile telephones offer the feature of personal identification number (PIN) protection. After switching on the phone, if the PIN security function is not switched off, the user is requested to enter a 4-8 digit PIN enabling the phone's non-emergency calling functions. If the wrong PIN is typed in more than three times, either the SIM card, the device or both become locked. They can be reverted to their original unlocked state by entering a PUC, provided by the service operator through verification. If the wrong PUC is entered ten times in a row, the device will become permanently blocked and unrecoverable, requiring a new SIM card. Cellular phone users are therefore advised by most providers to keep their PUC written down in a safe place separate from the device.

You can get the PUK Code from service provider......

PUK codes are Personal Unblocking Keys. The SIM card gets blocked when an incorrect PIN number is entered too many times. You can only get them from your network service provider.

Hello,
PUK is "personal unblocking key" if you enter wrong PIN, Personal Identification Number thrice then you need the PUK, which is 8 digit.

If you enter wrong PUK ten times then it will be blocked permanently and there is no way to use PUK blocked sim again.

your PUK can be gotten from your starter pack. The starter pack is the pack which was given to you when you bought the sim.

Please, kindly rate my solution.

Check Ur Blocked Numbers list once......

First check whether Ur number is not added in blocking numbers list of that mobile......

Get in touch with the Phone service provider
and just switch off ur phone or else ur sim card will be blocked and get the PUK number so that it can be unbllocked

you'll need to ring your phone company, they'll have the code for you

This code generates some random number to test.


#include <limits.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{ findLargest();
return 0;
}

int findLargest()
{ int someNumbers[50];
int i;

// to generate some numbers for us to test
for(i=0; i<50; i++)
// generate a random number between 0-100
someNumbers[i] = rand() % 100;

// for keeping track of numbers, set as smallest possible
int largest = INT_MIN;
int largest2 = INT_MIN;

// go through each item in the array
for(i=0; i<50; i++)
{ // if bigger than our previous max, set as new max
if (someNumbers[i] > someNumbers[largest])
largest = i;
// if it's not been set as new max, and is bigger than current 2nd largest
else if(someNumbers[i] > someNumbers[largest2])
largest2 = i;

// for printing all numbers in the array
printf("%d | %d\n",i, someNumbers[i]);
}

// print largest numbers and their position in the array
printf("largest %d (pos %d).\n2nd largest %d (pos %d)",
someNumbers[largest],
largest,
someNumbers[largest2],
largest2
);

return 0;

}
