用C编写的程序如下。include "math.h"main(){ long int m, num = 0;printf("\nPlease input num: ");scanf("%ld", &m);num = (3*pow(m,11)+8*pow(m,9)-6*pow(m,6)+5*pow(m,2)+20);printf("\n%ld\n", num);getch();} 参考资料：lengxieyaner 的回答 ...
如果输入输出不是很复杂的话，没有这么麻烦的：include<conio.h> include<stdio.h> main(){ char a[20]={NULL};int i=0,num;printf("输入: ");while(1){ a[i]=getch();if(a[i]==13) break;printf("%c",a[i]);i++;} num=i;printf(" 输出: ");for(i=0;i<num;i++)p...

c语言中不可以用变量定义数组的个数。可以使用mallo函数 mallo函数返回的实际是一个无类型指针，必须在其前面加上指针类型强制转换才可以使用；指针自身=(指针类型*）malloc（sizeof（指针类型）*数据数量）；int*p=NULL;intn=10;p=(int*)malloc(sizeof(int)*n);...
是因为取余数的运算符%只能用于整数，不能用于浮点数，而由于pow函数返回为浮点数，x/pow(10,i)肯定是浮点数，因此会报错。
