[C++] Why the result of my programme is "烫烫烫烫烫烫烫烫"?

my C++ code:








#include %26lt;windows.h%26gt;


#include %26lt;iostream%26gt;


#include %26lt;fstream%26gt;


using namespace std;





int main()


{


char a[128]="**** the truth!";


cout%26lt;%26lt;a%26lt;%26lt;endl;





ofstream outfile("temp.txt",ios::out);


for(int i=0;i%26lt;=127;i++)


{if(a[i]!=NULL)outfile%26lt;%26lt;a[i];}


outfile.close();





char b[128];


ifstream infile("temp.txt",ios::in);


for(int j=0;j%26lt;=127;j++)


{infile%26gt;%26gt;b[i];}


cout%26lt;%26lt;b%26lt;%26lt;endl;


infile.close();





return 0;


}











result：


**** the truth!

Probably because of this code





for(int j=0;j%26lt;=127;j++)


{infile%26gt;%26gt;b[i];}





Your for loop increments j but in the loop you are using b[i].


i should have a value of 127 or rubbish if it is out of scope.
