Write a Python program to count the number of occurrences of a specific character in a string

Sure, here is a simple Python program that counts the number of occurrences of a specific character in a string:

def count_char(string, target_char):
    count = 0
    for char in string:
        if char == target_char:
            count += 1
    return count

# Test the function
print(count_char("Hello World", "o"))  # Output: 2

In this program, we define a function count_char that takes a string and a target character as input. It initializes a counter count to 0. Then it iterates over each character in the string. If the character is equal to the target character, it increments the counter. Finally, it returns the count.

The test call count_char("Hello World", "o") counts the number of "o" characters in the string "Hello World", and prints the result.
