How do I save for loop plots to a figure directory?

I am completely new to MatLab. I was intructed to create a string variable that contains the name of a directory I made (a folder called OutputFigures which is found in C:\Users\sfai\Documents\MATLAB\OutputFigures).
How do I make this string variable? I tried the following but I am not sure if it is correct:
OutputFigures = 'C:\Users\sfai\Documents\MATLAB\OutputFigures';
When trying to save plots to this folder, I kept getting an error message stating that the file and/or folder path was invalid or missing. It only worked when I used 'OutputFigures/' which you will see below.
Then I made the following 5 plots using a forloop. I was instructed to save the plots (with corresponding figure names, Fig.1, Fig.2 etc) to the directory I made. I am getting stuck on saving my plots to the directory I made, OutputFigures.
Hints I was given to use: Hint#1: Use the "saveas(gcf,...) function to save the file. Hint#2: Concatenate strings to create the correct file and folder path.
I found out one way to save the plots in the correct location with correct names:
saveas(h,sprintf('OutputFigures/FIG%d.png',i));
However, I don't think this "concatenates strings".
When I try the following:
saveas(gcf, [strcat('Figure #', num2str(i), '.png')]);
I get the plots, but I don't know how to save them to the directory I created.
And when I try to save them like so, it only saves one figure titled "name":
name = [strcat('Figure #', num2str(i), '.png')];
% saveas(gcf, 'OutputFigures/name.jpg');
Any help is greatly appreciated. Here is the complete code:
plot_points = [1:5]
color = ["r", "g", "b", "m", "b"];
OutputFigures = 'C:\Users\sfai\Documents\MATLAB\OutputFigures';
for i=1:5
h=figure
plot(plot_points,plot_points,color(i))
xlabel('X')
ylabel('Y')
title(strcat({'Figure # '}, num2str(i)))
%% How can I us saveas(gcf,...) function to save the file and concatenate strings to create the correct file and folder path?
end
