C :

int main(){ 
	int i,j,n,a[101],k,temp;
	
	scanf("%d",&n) ;
	
	for(i = 0;i < n;i++){

C++ :

#include <iostream>
using namespace std;

int main(){
	//选择排序 
	int n,i,j,min,t;
	cin>>n;
	int a[n];
	for(i = 0;i < n;i++){

		}
	}
	
	for(i = 0;i < n;i++){
		cout<<a[i]<<" ";
	}
}

Pascal :

var a:array[1..100] of integer;
    i,j,t,n:integer;

begin
  readln(n);
  for i := 1 to n do
    read(a[i]);

   readln;
  for i:= 1 to n - 1 do
   begin
    for j := 1 to n - i do
     begin
       if a[j]  > a[j + 1] then
        begin
         t := a[j];
         a[j] := a[j + 1];
         a[j + 1] := t;
        end;
     end;
   end;

  for i:= 1 to n  do
   begin
   if i <> n then
     write(a[i],' ')
   else
     writeln(a[i]);
   end;

end.
