I am encountering a runtime error in my C$++$ program. The output shows Value $=7,$ followed by multiple instances of the message "Invalid assignment operator." After that, the program crashes with an exit code $139($interrupted by signal $11$: SIGSEGV$),$ which indicates a segmentation fault.

Problem Context:

The program seems to be working up until the assignment of a value, but the assignment operator is being reported as invalid.

The segmentation fault $($SIGSEGV$)$ occurs shortly after this issue.

I$$ve verified that the input file is correct and that the code contains std::cout statements for debugging.

What I$$ve Tried:

Checked for infinite loops and added print statements for debugging.

Verified that the input file is in the correct location and contains valid data.

Tried debugging with breakpoints but still facing the same issue.

Can someone help identify why this issue is occurring and suggest possible solutions?

Value $=7$

Invalid assignment operator

Invalid assignment operator

Process finished with exit code $139($interrupted by signal $11$:SIGSEGV$)$
