Part 1

1.1

#include 
     
       const int N=5;int main() {    int a[N] = {
   1, 2, 3, 4, 5};    int i;    for(i=0; i
     

1.2

#include 
     
       const int N=5;int main() {    char a[5] = {
   'h','e','l','l','o'};      int i;    for(i=0; i
     

1.3

#include 
     
       const int N=5;int main() {    double a[5] = {
   1.0,2.0,3.0,4.0,5.0};     int i;    for(i=0; i
     

 

Part 2

2.1

#include 
     
       int main() {    int a[5];     a[0] = 1;       a[1] = 9;    a[2] = 8;    a[3] = 6;    a[4] = 0;        printf("a[0] = %d\n", a[0]);    printf("a[1] = %d\n", a[1]);    printf("a[2] = %d\n", a[2]);    printf("a[3] = %d\n", a[3]);    printf("a[4] = %d\n", a[4]);    return 0;}
     

2.2

#include 
     
       int main() {    int a[5] = {
   1, 9, 8, 6, 0};      int i;    for(i=0; i<5; i++)         printf("a[%d] = %d\n", i, a[i]);    return 0;}
     

2.3

#include 
     
       int main() {    int a[] = {
   1, 9, 8, 6, 0};      int i,n;    n = sizeof(a) / sizeof(a[0]);    for(i=0; i
     

2.4

#include 
     
       int main() {    int a[5] = {
   1, 9};      int i;    for(i=0; i<5; i++)         printf("a[%d] = %d\n", i, a[i]);    return 0;}
     

 

Part 3

3.1

#include 
     
      const int N=5;int main() {    int score[N] = {
   99, 82, 88, 97, 85};     int i;     for(i=0; i
     

3.2

#include 
     
      const int N=5;void print(int x);int main() {    int score[N] = {
   99, 82, 88, 97, 85};    int i;    for(i=0; i
     

3.3

#include 
     
      const int N=5; void init(int a[],int n, int value);  int main() {    int b[N],i;    init(b,N,-1);      for(i=0;i
     

 

Part 4

#include 
     
      const int N=5;void bubblesort(int [],int);int main(){    int i,a[N];    printf("请输入%d个整型数据: \n",N);    for(i=0;i
      
       x[j+1]){                t=x[j];                x[j]=x[j+1];                x[j+1]=t;            }        }    }}
      
     

 

Part 1-4总结

1.下标必须为整型值，表示了数组元素的位置

2.函数声明和函数定义中，函数名init后面括号里出现的是形式参数，数组名后面要加[ ]

 

Part 5

5.1

#include 
     
      int findMax(int a[], int n); const int N=5;int main() {    int a[N];    int max, i;    printf("输入%d个整数: \n", N);        for(i=0;i
      
       max)        max=a[j];    }    return max;}
      
     

5.2

#include 
     
      const int N=4;void output(char x[], int n);  // 函数声明 // 排序函数声明void function(char a[],int n); int main() {    char string[N] = {
   '2','0','1','9'};    int i;        printf("排序前: \n");    output(string, N);        // 调用排序函数对字符数组中的字符由大到小排序     function(string,N);            printf("\n排序后: \n");     output(string, N);        printf("\n");        return 0;    } // 函数定义// 函数功能描述：输出包含有n个元素的字符数组元素// 形参：字符数组，以及字符数组元素个数void output(char x[], int n) {    int i;        for(i=0; i
      
       a[j+1])            {                t=a[j];                a[j]=a[j+1];                a[j+1]=t;            }        }    }}
      
     

 最后一个题不知道为什么一直报错，求大佬帮忙
