Duct tape can fix Mother's Day
Brainfuck
Oh god why did I do this to myself?
It is actually possible to find each BF symbol by itself as a code snippet in some answer somewhere. The interesting bit was piecing together bits of other people's code, each representing a block of BF instructions. Unfortunately there are basically no unmatched [ and ] symbols out there, so I had to cheat a bit for those, and I had to get an awful lot of mileage out of a funky Haskell snippet which had a bunch of pluses in it. There are probably others out there. Beyond that, here's some Frankensteined code:
byte x = 1;
byte y = 2;
byte z = x + y;   // ERROR: Cannot implicitly convert type 'int' to 'byte'
addop = do {symb &quot;+&quot;; return Op Add}  +++ do {symb &quot;-&quot;; return Op Sub}
addop = do {symb &quot;+&quot;; return Op Add}  +++ do {symb &quot;-&quot;; return Op Sub}
addop = do {symb &quot;+&quot;; return Op Add}  +++ do {symb &quot;-&quot;; return Op Sub}

int a = (b &gt; 10) ? some_value                 
                 : another_value;
addop = do {symb &quot;+&quot;; return Op Add}  +++ do {symb &quot;-&quot;; return Op Sub}
