I need help to fix my output of this C++ code. I am getting this weird symbols on the second result of the code.

Here is the code:

#include #include #include

using namespace std;

int main() { ifstream in; in.open("studentans.txt"); ofstream out; out.open("results.txt");

char* ans = new char[100];

in.getline(ans, 100);

char** id = new char*[10000]; char** responses = new char*[10000];

for(int i = 0; i

int size = 0;

char* ch = new char[100]; while(in.getline(ch,100)) { int i = 0;

while(i

for(int j = 0;j

for(int i = 0; i

int correct = 0, wrong = 0;

for(int j = 0; j

if(avg >= 90.0) grade = 'A'; else if(avg >= 80.0) grade = 'B'; else if(avg >= 70.0) grade = 'C'; else if(avg >= 60.0) grade = 'D'; else grade = 'F';

out

in.close(); out.close();

return 0; }
