Program to count occurrence of a given character in a string
Given a string and a character, task is to make a function which count occurrence of the given character in the string.
Examples:
Input : str = "geeksforgeeks"
c = 'e'
Output : 4
'e' appears four times in str.
Input : str = "abccdefgaa"
c = 'a'
Output : 3
'a' appears three times in str.
