Question

How to generate N pairs of random digits in C

Answer 1

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

// Function to generate and print N random digit pairs
void generateRandomPairs(int N) {
    printf("Random pairs of digits:\n");
    for (int i = 0; i < N; i++) {
        int firstDigit = rand() % 10;  // Random digit between 0 and 9
        int secondDigit = rand() % 10; // Random digit between 0 and 9
        printf("(%d, %d)\n", firstDigit, secondDigit);
    }
}

int main() {
    int N = 15;

    // Seed the random number generator
    srand((unsigned)time(NULL));

    generateRandomPairs(N);

    return 0;
}
