我創建的模型我的數據庫: class Album(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(128))
year = db.Column(db.String(4))
tracklist = db.relationship('Track
下面是程序, #include<stddef.h>
#include<stdlib.h>
#include<string.h>
#include<stdio.h>
#define INITIAL_ARRAY_SIZE 10
typedef struct{
int *a;
int lastItem; //Location of lastest element sto
爲了重構程序,我花了一個複雜的過程來抽象並將其放入宏中。 %macro BlackBox();
data _null_;
put "This represents a complex process I want to abstract.";
run;
%mend;
該過程需要連續發生多次,所以顯而易見的解決方案是將其放置在循環中。 data _null_;
Test.java public class Test {
public void go(){
System.out.println("Test go");
}
}
Test2.java public class Test2 extends Test {
public void go(){
System.out.println("Test 2
