Question

How I can write a program to sort 2D array using C language and without using pointer,
just looping and if statements and using only main function

the array

7  5  2
3  1  4
6  9  8

and will be

1  2  3
4  5  6
7  8  9

please if you can post a sample code 🙂
Thanks a lot

Try searching the web before posting such questions. Any ways this is a bubble sort implementation in c:

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

#define ARRAY_SIZE 20

void print_array(int *array) {
    int x;
    for(x = 0; x < ARRAY_SIZE; x++) {
        if(x != ARRAY_SIZE-1)
            fprintf(stdout, "%d, ", array[x]);
        else
            fprintf(stdout, "%d\n", array[x]);
    }
}

int main() {
    int iarray[ARRAY_SIZE];
    int x, y, holder;

    // Seed rand()
    srand((unsigned int)time(NULL));

    for(x = 0; x < ARRAY_SIZE; x++)
        iarray[x] = (int)(rand() % 100);

    fprintf(stdout, "Before Sort\n---------------\n");
    print_array(iarray);  


    // Bubble sort method.
    for(x = 0; x < ARRAY_SIZE; x++)
        for(y = 0; y < ARRAY_SIZE-1; y++)
            if(iarray[y] > iarray[y+1]) {
                holder = iarray[y+1];
                iarray[y+1] = iarray[y];
                iarray[y] = holder;
            }

    fprintf(stdout, "\nAfter Sort\n---------------\n");
    print_array(iarray);  

}
