1、构建学生对象并且打印相关信息

代码： 
#import <UIKit/UIKit.h>
#import "AppDelegate.h"

@interface Student : NSObject
//变量
@property NSString *name;
@property int age;
@property float score;

//method
-(void)show;

@end

@implementation Student
-(void)show{
    NSLog(@"%@的年龄是%d成绩是%f", self.name, self.age, self.score);
}
@end



int main(int argc, char * argv[]) {
    //alloc函数为队形分配内存空间，init函数会初始化函数对象
    Student *stu = [[Student alloc]init];
    stu.name = @"chenyu";
    stu.age = 25;
    stu.score = 100;
    [stu show];
    return 0;
}
