How to run program after compiling with Makefile

I have a assign4a.cpp, list.h, and list.cpp file. I compiled them with my make file but don't know what command I would use to run the program.

What I tried to run have tried

a.out and ./a.out

both of them give me "Command not found"

Makefile

CFLAGS = -c -Wall -g
LFLAGS = -g -o assign4a

assign4a: assign4a.o list.o
    g++ assign4a.o list.o $(LFLAGS)

assign4a.o: assign4a.cpp list.h
    g++ $(CFLAGS) assign4a.cpp

list.o: list.cpp list.h
    g++ $(CFLAGS) list.cpp

clean:
    rm -f assign4a *.o *~ *#
