Make me a s'more! I tell you the width, the amount of graham cracker, the amount of chocolate, and the amount of marshmallow. An example:

Input:

Width: 10 Graham: 3 Chocolate: 2 Marshmallow: 1.

Output:

GGGGGGGGGG
GGGGGGGGGG
GGGGGGGGGG
CCCCCCCCCC
CCCCCCCCCC
MMMMMMMMMM
GGGGGGGGGG
GGGGGGGGGG
GGGGGGGGGG

Is it that easy? Um... yes.

Note that the input should be a list of arguments to a function or a program, not a string. You might choose the first being Width, then Graham, but any order is fine.

Full test cases if you are interested.

Stack snippet (for testing, etc.)

This is to test the output.

var smore = function(width, graham, chocolate, marshmallow){
	return ("G".repeat(width) + "\n").repeat(graham) + 
	("C".repeat(width) + "\n").repeat(chocolate) + 
	("M".repeat(width) + "\n").repeat(marshmallow) + 
	("G".repeat(width) + "\n").repeat(graham);
};
Snippetify(smore);
<script src="https://programmer5000.com/snippetify.min.js"></script>
Width: <input type = "number">
Graham: <input type = "number">
Chocolate: <input type = "number">
Marshmallow: <input type = "number">
<button>Try it out!</button>
<pre data-output></pre>

Notes:

  • You may include a trailing newline on the end of the last line. You may also use a \ instead of a newline.

    \$\begingroup\$ Some answers are assuming flexible input order and format (as usual in PPCG), but the challenge seems to require a specific order and rule out strings (not sure what that means). Can you clarify? \$\endgroup\$

    \$\begingroup\$ Thanks for clarifying. You should then reword the sentence the input should be a list of arguments to a function or a program, not a string, with the first being Width, then Graham, etc. Personally I would say something like "Input format is flexible as usual" \$\endgroup\$

Trying this strrep function I just heard about... Probably a intToUtf8 approach could do better than that. Thanks @Shaggy for pointing an issue...fixing it saved 6 bytes.

    \$\begingroup\$ @programmer5000 Hehe, thanks! I like golfing in Java 7 (and sometimes 8), although I don't think it will ever even compete with other answers.. The only time 'somewhat competed' with a Java answer was with this 8 byte answer and this 19 byte answer, actually outgolfing Python for the first time. ;p Although those golfing languages with their 1 or 2 byte submissions still leave Java in the dust of course. \$\endgroup\$

Mathematica 102 Bytes (100 Characters)

Heard the s'mores built-in isn't coming out til V12.

s=StringRepeat;StringReplace[s@@@({Characters@"GCMG",#/.#[[4]]->#[[1]]})<>"",x_:>x~s~#[[4]]<>"\n"]&

Pretty straightforward using the idea of building up a column first. Long function names waste 35 bytes. The one box-looking symbol is actually a transpose character and will paste into Mathematica just fine.

Usage: %@{Graham, Chocolate, Marshmallows, Width} e.g. %@{3, 2, 1, 11}

This stored procedure loops for the first layer or graham, chocolate, and Marshmallow with a GOTO in order to print up to the established amount. For the last layer of graham the fourth optional parameter (previously setted to the @g value) is used to do the same as the first layer of graham. The width of the layer is created with the REPLICATE function.

Usage:

EXECUTE S @ = 5, --Width
    @g = 7, --Graham
    @c = 8, --Chocolate
    @m = 4, --Marshmallow
    @b = NULL --Control variable, can be ignored
