IOS编程学习笔记

@interface
-实例对象
+类名

#import "MyClass"

@implementation MyClass
-(id)initWithString:(NSString*)name
{
}
+()


int max,min;
int array[30],sum=0;
for(int i=0;i<30;i++)
{
rand100=(((double)rand()/(double)max)*max+min);
array[i]=rand100;
sum+=array[i];
}

不同的鸡兔吃的东西多少不一样，而每次有不一样



#include<iostream>
using namespace std;

int main()
{
    int a[5] = { 1, 5, 7, 9, 25 }, b[5] = { 1, 27, 26, 38, 99 };
    int *c = new int;
    int k=4,j=4;
    for (int i = 0; i < 10; i++)
    {
        if (a[j] > b[k])
        {
            c[i] = a[j];
            j--;
        }
        else
        {
            c[i] =b[k];
            k--;
        }
    }
        for (int i = 0; i < 10; i++)
            cout << c[i] << " ";
}


return self=C语言中的*this

if(self)
{
power=0;
}
return self;
