Error in code running

[smokei21]

The simplest C code wont run multiple times, like I made a menu driven code for linked list, and it only takes inputs max 2 times and then the compiler stops responding...... same issue is with C++ language and java programs wont even run, the python programs are running just fine. Am I doing something wrong, or is the app that has some issues and glitches ..... please respond and help ASAP
