Question

a[10]={1,2,3,4,5,6,7,8,9,10}利用指针将数组a中10个整数按相反顺序存放

a[10]={1,2,3,4,5,6,7,8,9,10}利用指针将数组a中10个整数按相反顺序存放

Answer 1

#include <stdio.h>
int main(){
int a[10]={1,2,3,4,5,6,7,8,9,10};
int *p=a;
int i,t;
for (i=0;i<5;i++) {t=*(p+i); *(p+i)=*(p+9-i); *(p+9-i)=t;};
for (i=0;i<10;i++) printf("%d ",a[i]);
return 0;
}
