Sua cho em bai code nay voi:

#include<stdio.h>
void DesSort (int a[], int n)
{
  int i,j,tmp;
  for(i=0;i<n-1;i++)
    for(j=i+1;j<n;j++)
      if(a[i]<a[j])
	{
	 tmp=a[i];
	  a[i]=a[j];
	  a[j]=tmp;
	}
  int main()
  {
     int tmp,i,n,a[100];
 printf("Nhap so phan tu trong mang: ");
  scanf("%d",&n);
  printf("Nhap cac phan tu cua mang:\n");
  for(i=0;i<n;i++)
    {
      printf("Phan tu thu %d\n",i+1 );
      scanf("%d",&a[i]);}
  }
  printf("Sap xep lai mang theo thu tu giam dan:\n");
  DesSort(a);
}

Bạn viết code hơi… vô tổ chức nhỉ?
Loáng thoáng thì mình thấy void kia thiếu } ở cuối. Thuật toán không sai.

ban sua giup mk dc k?

[noname00 (HK boy)]

Code trong hàm main kìa, dòng DesSort(a) của bạn truyền thiếu tham số n.

[umisanto]

y ban la DesSort(a,n)?

[noname00 (HK boy)]

Đúng rồi đó…

DesSort cuối cùng, bạn quên truyền n kìa, hàm của bạn là DesSort(int a[], int n) mà
