C语言看了一段时间，感觉没啥进步，都在原地踏步，啥时候能有所突破呢。唉.....

#include <stdio.h> int main(void) { char id[17]; int idx[17]={7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2}; char last[11]={'1','0','X','9','8','7','6','5','4','3','2'}; int sum=0,i; printf("Please input ID:"); for (int i=0;i<17;i++) { scanf("%c",&amp;id[i]); //printf("%c",id[i]); ...

第9题： #include <stdio.h> double inpr(const double*a,const double*b,int n); int main(void) { double a1[3]={1.1,2.2,3.3}; double b1[3]={4.4,5.5,6.6}; printf("%.2f",inpr(a1,b1,3)); return 0; } double inpr(const double*a,const double*b,int n) { const double *...

#include <stdio.h> #define N 10 void ftl(int [],int,int*,int*); int main(void) { //int a[N]={1,287,100,92,287,920,56,98,24,88}; int big,big2; for(int i=0;i<N;i++) { printf("a[%d]==",i); scanf("%d",&amp;a[i]); } ftl(a,N,&amp;big,&amp;big2); printf("\n\n\n1st==%d...

#include <stdio.h> void ar1(int[],int); int main(void) { int a[13]={5,-9,3,0,-4,8,-1,7,6,2,-1000}; ar1(a,10); printf("最大数为：%d\n",a[10]); printf("\n平均值为：%.2f\n",(double)a[11]/10); printf("\n正整数共有 %d 个" ,a[12]); return 0; } void ar1(int a[],int n) { for(int i=0;...

C越来越看不下去了，咋办啊
