Since, I posted the first post in this thread I have found that GCC sets explicit versions of at least different 4 values; still have not found where std=gnu++98 is set.

But, I have decided to...

Found the exact command; will try using C++11 standard next. -std=gnu++11



i686-w64-mingw32-g++ -std=gnu++98 -fno-PIE -c -DIN_GCC_FRONTEND -g -D__USE_MINGW_ACCESS -DIN_GCC -fno-exceptions...

../../gcc-git/gcc/cp/coroutines.cc:2700:22: warning: defaulted and deleted functions only available with '-std=c++11' or '-std=gnu++11'
2700 | var_nest_node () = default;


gcc/coroutines.cc...

The next thing to try would be commenting out this line


TMR0 = 0;

In the interrupt tc_int.

Been over 10 years since I did PIC programming.

Looking at your code; I question this line.



S=0;


Would not

Looks like Microchip C code; no idea which MCU.

Tim S.

It should be okay; unless you have a real old compiler!
If you got a warning about shadowing you do have that problem.

Tim S.

Sorry, I missed you are passing it in; still think that


ptr_arr[0] = '\0';

defaults to an int array as in the K & R days.

NOTE: It no longer does that.

Tim S.

Since you refuse to tell me if you are supposed to use malloc I give up helping you. But, since I am not that good using malloc I would likely have given up if you said yes.

Tim S.

Maybe maybe not! As I have already said it is implementation defined. If a book said that is the way it is always done, throw away that book!
The CPU and the OS normally defines the way it is done!...

FYI: The use of "conio.h" usually means the student is learning from a poor instructor in India.

Are you supposed to use malloc in this assignment?

What you are asking is implementation defined for the most part.

Post your code! If you have build errors post the errors!

Tim S.

Find another book because you have no idea what you are doing!

If I tell you to remove the Ace of Spades from a deck?
What card would you remove?

Edit: Please do not ever PM again!! If you do...

The code is crap; throw it out and start over or use the advise and fix it!

Asking over and over what is wrong is a waste of time!

You need to learn the difference between build and run-time errors.
And, when you get an build error post it.

Tim S.

std::sort - cppreference.com

This is wrong!



char exitConditon[]={"0"};


You need an zero terminated character array to use as an C-String!

"0" is not equal to 0

The second one likely used double instead of float to store the result.

Learn the difference between == and = when used in C code.

Edit: And, you are casting it wrong even for C++ in at least two places!

This below is considered improper; but, will likely work most of the time.

(char*)...

STOP casting the result of malloc when programming in C.

If you have a compile error; post the error!!

Tim S.

You can only "return" a value from a function two ways.
1. Using a return statement. Can only return a single value (which can be a structure)
2. Passing the address of where you wish the result...
