$4\mathrm{.}15$ LAB: Count characters

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n$\text{'}$s$,$ if the number of times the characters appears is not exactly $1.$

Ex: If the input is:

n Monday

the output is:

$1$ n

Ex: If the input is:

z Today is Monday

the output is:

$0$ z $\text{'}$s

Ex: If

n It's a sunny day

the output is:

$2$ n$\text{'}$s

Case matters.

Ex: If the input is:

n Nobody
