Question

c++里面怎么用–>对结构体数组指针里面的某一个元素的值进行从大到小排序？

Answer 1

#include<stdio.h>

struct A { int a[N]; };

void main() { struct A x,*p; int i,j,k;

for ( i=0;i<N;i++ ) scanf("%d",&x.a[i]); p=&x;

for ( i=0;i<N-1;i++ )

for ( j=i+1;j<N;j++ ) 

if ( (p->a[i])<(p->a[j]) ) {k=p->a[i];p->a[i]=p->a[j];p->a[j]=k;}

for ( i=0;i<N;i++ ) printf("%d ",p->a[i]); printf("\n");

}
