What is the following program doing given that the user inputs one character into variable a______________? (assume correct indentation)

s = input()

a = input()

c = 0

for i in range(len(s)):

if a == s[i]:

c = c + 1

print (c)

		computing the sum of numbers
		searching for the letter c in a sentence
		it will not do anything because it has syntax errors
		counting how many times a character occurs in string s
