Above is how it looks where I code but the output is something like this: The numbers dont come right below one another..:

Enter the number associated with the combination of salts available. Enter 0 if none of the combinations are available.

1:Two of these chlorides 1) NH4Cl(ammonium chloride) 2) MgCl2(magnesium chloride) 3) CaCl2(calcium chloride) 4) NaCl(sodium chloride) 5) KCl(potassium chloride)

2:ZnBr2(zinc bromide) & 1) NH4Cl(ammonium chloride) 2) MgCl2(magnesium chloride) 3) CaCl2(calcium chloride 4) NaCl(sodium chloride) 5) KCl(potassium chloride)

At this point you should consider creating a small GUI for your input selection. But for your question at hand: you forgot to allign the start of the rows, so you missed the fact that they were actually shifted. The smart allign button in the editor and a few spaces gets you this:

combinations_available=input(['Enter the number associated with the combination of salts available. Enter 0 if none of the combinations are available.'...

With the result in the command prompt:

Enter the number associated with the combination of salts available. Enter 0 if none of the combinations are available.

Just because you have the two literal characters \ and n in that order in a char vector or string array, MATLAB won't automatically treat those as a newline. You could tell MATLAB to include the newline character by using the newline function (introduced in R2016b) or using sprintf (introduced a long time ago) or compose (also introduced in R2016b).

The problem was here:

combinations_available=input(['Enter the number associated with the combination of salts available. Enter 0 if none of the combinations are available.'...
      '\n1:Two of these chl
%  |^^
     '\n2:ZnBr2(zinc bromid
%  |^
    '\n3:NH4
%  |

You don't have to change you code, just remove the three spaces indicated with ^ above. Then you will see why you're allignment was incorrect. I corrected it in the code block in my answer.
