I always use the gcc compiler, so I'd personally create a makefile:

SRC = $(wildcard *.c) # if there is a source path, put that before the '*' and make sure to end with /
HDR = $(wildcard *.h) # same for this one
COMPILE = gcc -Warn -o main.o main.c # -Warn shows warning

.PHONY: create
.PHONY: clean

create: ${SRC} ${HDR}
    ${COMPILE} ${SRC} ${HDR} # this does 'gcc -Warn -o main.o main.c' then all of the SRC(.c) files and HDR(.h) files

clean: # cleaning all output files for the project
    rm *.o

Then, within the .replit file, put:

language='c'
run='make create && ./main.o'

To me personally this is the easiest way to fully compile the project. I always use gcc and makefiles to compile my projects

language = "c"
run = "C ./arknights_pulls_simulation.c"

That's it
Thanks!

Hope this helps

Something like:

run="g++ -std=c++0x *.cpp -o example_program"
