如何将唯一名称随机分配给C中的一系列数字

问题描述

I have generated a series of number , how to randomly assign name to it from a set of name. Let say I have, Vertex [i]: n,
Vertex [0]: 1
Vertex [1]: 5
Vertex[2]: 9
.
.
.
Vertex[19]: 13

and a set of name : { apple, orange, papaya, watermelon, pineapple}

And what I want to do is when I key in 0 ( i value) which is for the first item, it will print 
Vertex [0]: 1 { orange } 
means it will pick one name from the list and random assign to n 

我的尝试：

What I have tried:

printf("=======================\n\n");
    printf("Number of Edges for each node:\n");
    for( i = 0 ; i < N ; i++ )
    {
        printf("Vertex %d: ",i);
        n=0;
        for( j = 0 ; j < N ; j++ )
        {
            if(graph[i][j])
                n+=1;  ////count the number of repeat
        }

        if(n>max)max=n;
        if(n<min)min=n; printf("%d="" ",="" n);="" printf("\n");
