【资料备份】c++声明二维变长数组，并用memset赋予0值

示例代码#include"stdafx.h"



#include<iostream>

usingnamespacestd;

int_tmain(intargc, _TCHARargv[])

{

strings1="123456";

strings2="abc";



intcount=newint[s2.size()];

for(inti=0;i<s2.size();i++)

{

count[i]=newint[s1.size()];

memset(count[i],0,sizeof(int)*s1.size());

}



for(inti=0;i<s2.size();i++)

{

for(intj=0;j<s1.size();j++)

{

cout<<count[i][j]<<endl;

}

}

for(inti=0;i<s2.size();i++)

{

delete[]count[i];

}

delete []count;

cout<<"finish"<<endl;

intend;

cin>>end;
