###1.通过指针引用数组 ![图片描述](https://dn-simplecloud.shiyanlou.com/courses/uid3455135-20250321-1742544328638) ![图片描述](https://dn-simplecloud.shiyanlou.com/courses/uid3455135-20250321-1742544342346) ![图片描述](https://dn-simplecloud.shiyanlou.com/courses/uid3455135-20250321-1742544355466) ###2.用数组名作函数参数 #####数组 a 中 n 个整数按相反的顺序存放的集中写法：我的写法：嵌套调用、指针变量作为参数交换数组元素的值、数组名作参数； ``` #include int main(){ void change(int x[],int n); int a[10]={3,7,9,11,0,6,7,5,4,2}; for(int i=0;i<10;i++) printf("%d",a[i]); printf("\n"); change(a,10); for(int i=0;i<10;i++) printf("%d",a[i]); } void swapArray(int *a,int *b){ int temp; temp=*a; *a=*b; *b=temp; } void change(int x[],int n){ int m=(n-1)/2; //通用(n-1)/2 for(int i=0;i<=m;i++){ swapArray(x+i,x+n-1-i); } } ``` 实验楼提供的： ``` //1、 #include int main(){ void change(int x[],int n); int i,a[10] = {3,7,9,11,0,6,7,5,4,2}; printf("the original array:\n"); for(i=0;i<10;i++) printf("%d\t",a[i]); printf("\n"); change(a,10); printf("the array has been inverted:\n"); for(i=0;i<10;i++) printf("%d\t",a[i]); return 0; } void change(int x[],int n){ int temp,i,j,m=(n-1)/2; for(i=0;i<=m;i++){ j = n - 1 - i; temp = x[i]; x[i] = x[j]; x[j] = temp; } } ``` ``` //2 #include int main(){ void change(int *x,int n); int i,a[10] = {3,7,9,11,0,6,7,5,4,2}; printf("the original array:\n"); for(i=0;i<10;i++) printf("%d\t",a[i]); printf("\n"); change(a,10); printf("the array has been inverted:\n"); for(i=0;i<10;i++) printf("%d\t",a[i]); return 0; } void change(int *x,int n){ int *p,temp,*i,*j,m = (n-1) / 2; i=x;j=x+n-1;p=x+m; for(;i<=p;i++,j--) { temp = *i; *i = *j; *j = temp; } } ```
