Hi

I'm not a contributor to this project. But, I'm learning the course. If you tell me your compiler+version, the operating system and your architecture, I'll try to figure out what has gone wrong. But, If you just want a quick fix to proceed, change your line to:
tldr;
ptr = (int*) malloc(sizeof(int));

Update:
On my WSL:
gcc (C compiler) works perfectly.
g++ (C++ compiler) the same error!
nvcc (Cuda compiler works perfectly.
So, it given that the file's extension is .c using gcc command is recommended over g++.
