how to write a C code that “bubblesorts” the strings in a 2D array?

问题

#include <stdio.h>

int main()
{
    int N, i, j, k, z, v, x, c;
    
    printf("Determine the number of your words: \n");
    scanf("%d", &N);
    char dict[50][50];
    char tmp[50];
    for(i=0; i<N; i++)
    {
        printf("Determine your %d. word: \n", i+1);
        scanf("%49s", &dict[i]);
    }
    
    
    for(j=0; N-1; j++)
    {
        for(k=0; N-i; j++)
        {
            if(dict[k][0]>dict[k+1][0])
            {
                for(z=0; z<50; z++)
                {
                    tmp[z]=dict[k][z];
                }
                for(v=0; v<50; v++)
                {
                    dict[k][v] = dict[k+1][v];  
                }
                for(x=0; x<50; x++)
                {
                    dict[k][x]=tmp[x];
                }
            }
        }
    }
    
    for(c=0; c<N; c++)
    {
        
        printf("%s \n", dict[c]);
        
    }
    
    return 0;
}
    

So in my first semestr as a Ce student in college our task is to write a C code that (bubble)sort the strings in a 2D array according to their first characters position in the alphabet by only using the <stdio.h> library and I cannot get any resluts. I do not wish any answers. But I would be glad to be enlightened about the reasons I get this results. NOTES:we haven't really procceded on the terms of coding(which is the subject of the second semestr) so we don't create our own functions yet. I also cannot use any additional headings like int main void. I'm allowed to write code under only int main
