Although chord naming can vary, the usual convention is to use just the letter for the chord if it is a major chord. So:

C - C major (CEG)
Cm - C minor (CEbG)
Cdim - C diminished (CEbGb)
Caug - C augmented (CEG#)

C7 - C seventh (CEGBb)
Cmaj7 - C major seventh (CEGB) - the "major" refers to the seventh, not to the C chord.
C min7 - C minor seventh (CEbGBb) - The "minor" refers to the C chord, not to the seventh.
Cdim7 - C diminished seventh (CEbGbA) - The diminished refers to the C chord, not to the seventh. Actually there is no seventh in this chord (confused?).

These shoud get you started.

Also get a book of chords, or google "chord finder" and you will have loads of info.

Best wishes,

also (and it seems that you are already aware of this, as you demonstrated in the subject line of your post, that....)an upper case 'M' (ex: CM) refers to a major chord while a lower case 'm'  (ex: Cm) refers to a minor chord.

if you're talking about triads,the m-sufix means minor (C-Eb_G) and no suffix implicitely means major (C-E-G) so an "M" is never used to indicate a major triad.My first reflection when I see anything like CM will be C-E-G-B which is a four-tone chord.
btw,a little more exotic but this chord exists also : CmM or CmM7 which minor-major-seven chord,something like C-Eb-G-B.Not used that much as stable chord to build a piece around but often used (in jazz) as transition chord in constructions like | Cm | CmM7 | Cm7 | Cm6 |
Play it and listen,very nice accompaniment,instead of four bars Cm you can play this...depending on the musical context off course.
It naturally occurs on the first degree of a minor harmonic and melodic scale amongst others.
