C++ coding FILES

that should have output at txt file

supposedly it read input.txt file

The coding have no error however the output is not shown at the output.txt file, it should show these output:

out <<"Number of students: "<< i <

outfile << "Grade : " << grade[i] <

outfile << "The highest Marks is " << highest << endl;

the coding is also in the gDrive with input.txt and output.txt LINK IN THE COMMENTS
