$3\mathrm{.}9\mathrm{.}2$: Finding values in vectors.

Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM$\_$VALS elements. Ex: If userValues is $\{2,2,1,2\}$ and matchValue is $2,$ then numMatches should be $3.$

Your code will be tested with the following values:

$*$ matchValue: $2,$ userValues: $\{2,2,1,2\}($as in the example program above$)$

$*$ matchValue: $0,$ userValues: $\{0,0,0,0\}$

$*$ matchValue: $50,$ userValues: $\{10,20,30,40\}$
