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:

What can I do with this information to trace the problem?
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
