java - i want to search strings from domain file in log file...for reading two files i used nested loops...incorrect output -

- 

while((sline= bbr.readline()) != null) {     while ((line = br.readline()) != null){         if (line.contains(sline)){             tracker.append(line); tracker.append("\n  ");tracker.append("\n  ");                 string track = new string(tracker.tostring());              writetofile(c,track,"trackinginfo.txt");         }     }// end of while1 }// end of while2 br.close(); bbr.close();

i use nested loops first reading domain file , second logfile. first string domain file searches whole log file not other strings in domain file.

c++ - How to test/verify that zero-initialization takes place -

-
i trying test 0 initialization on virtual machine g++ options -std=c++98, -std=c++03, -std=c++11 unfortunately there not many garbage values , see zeros in place shouldn't be. how force random values can test this? #include <iostream> #include <string> using namespace std; class { public: int a; }; class b { public: b(){} int x; }; int main() { { int tab[50000] = {0}; } a; a* aa = new a; b b; b* bb = new b; cout << a.a << endl; cout << aa->a << endl; cout << b.x << endl; cout << bb->x << endl; return 0; } you not guaranteed see random numbers. c/c++ standard says uninitialized values undefined, cannot values have. 0 ok (maybe virual machine zeros memory before allocating). if need random numbers, generate them using <random>
