[語法] 看不懂的程式碼
關於動態記憶分布:
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
unsigned int no_of_size;
int *ptint,i;
cout<<"Input no of data :\n";
cin>>no_of_size;
ptint=(int *)calloc(no_of_size,sizeof(int));
if( ptint == NULL)
{
cout<<"No memory space for input data \n";
exit(1);
}
cout<<"Input the integer data \n";
for(i=0; i< no_of_size; ++i)
cin>>*(ptint+i);
cout<<"The input integer data are :\n";
for(i=0; i < no_of_size; ++i)
cout<<*(ptint+i)<<", ";
cout<<"\n";
free(ptint);
return 0;
}
我真的看不懂這個程式在做什麼... T^T
煩請高手解惑
感謝 m(_ _)m
