Is there a way to run a c++ file immediately using the sdl library without the need to repeatedly type the compiler flag?

Yes, you can create a makefile to automate the build process. A makefile is a script that automates the building of a program, including compiling, linking, and executing. Here is an example makefile for a simple SDL program:

CC=g++
CFLAGS=-Wall -std=c++11
LIBS=-lSDL2

all: myprogram

myprogram: main.o
    $(CC) $(LIBS) $< -o $@

main.o: main.cpp
    $(CC) $(CFLAGS) -c $< -o $@

clean:
    rm -f myprogram main.o

To use this makefile, save it as "Makefile" (case-sensitive) in the same directory as your main.cpp file. Then in a terminal, type:

make
./myprogram

This will compile and link the program, producing an executable file called "myprogram", which you can run with the second command. Whenever you make changes to your source code, you can simply run "make" again to recompile and relink the program.
