有错误，麻烦指导一下

第三行是分号;不是逗号

b[i-1]=a;
此处错误，应该是b[i+1]=a;

#include <stdlib.h>

    int i, j, a;

    srand((unsigned)time(NULL));
    /* Display GENERATE_NUM numbers. */
    for( i = 0; i < GENERATE_NUM; i++) {
        b[i] = rand();
        printf("%6d", b[i]);
    }
    printf("\n");

    for (j = 0; j < GENERATE_NUM; j++)

            }
    for (i = 0; i < GENERATE_NUM ; i++)
        printf("%6d",b[i]); 

    return 0;

你有的是"起泡法"排序对吧？改了点你试下....
