I’m experiencing some problems with my C program on Linux. It compiles and runs just fine on Windows. The Linux terminal returns this information:

    Compile your program with debug info then run with valgrind.

    gcc -g student.cpp -o student
valgrind ./student

    To try a debugger:

    gcc -g student.cpp -o student
gdb ./student
run
     // wait for it to crash
backtrace
help // to figure out what else you can do
