{
printf("out of memory,press any key to quit...\n");
exit(0); /*终止程序运行,返回操作系统*/
}
/*提示输入num个数据*/
printf("please input %d elements: ", num);
for (i = 0; i < num; i++)
{
scanf("%f", &array[i].coef);
scanf("%d", &array[i].expn);
}
/*输出刚输入的num个数据*/
printf("%d elements are: \n", num);
for (i = 0; i < num; i++)
{
printf("%f,", array[i].coef);
printf("%d,", array[i].expn);
}
printf("\b \n"); /*删除最后一个数字后的分隔符逗号*/
free(array); /*释放由malloc函数申请的内存块*/
}
这个已经开辟了数组但是我想在往结构体arry中添加信息，还要怎么分配，求解答！谢谢
