Hello Friends Today, through this tutorial, I will tell you how to generate a 6 digit Unique random number in C?.
In C, you can use the `rand` function to generate random numbers. Here’s an example of generating a 6 digit unique random number:
#include <stdio.h> #include <stdlib.h> #include <time.h> int generateRandom6DigitNumber() { return rand() % 900000 + 100000; } int main() { // Seed the random number generator with the current time srand(time(NULL)); // Generate a random 6-digit number int random6DigitNumber = generateRandom6DigitNumber(); printf("Random 6-digit number: %d\n", random6DigitNumber); return 0; }
In this example, `rand() % 900000 + 100000` generates a random number between 0 and 899999, and then we add 100000 to ensure that the number is always a 6-digit number.
