Count-Characters

Instructions

Write a function that, given a string and a character as arguments, returns an int representing the number of times the character appears in the string.

• if the character is not in the string return 0
• if the string is empty return 0

Expected Function

func CountChar(str string, c rune) int {
}

Usage

Here is a possible program to test your function:

package main

import "fmt"

func main() {
    fmt.Println(CountChar("Hello World", 'l'))
    fmt.Println(CountChar("5  balloons",5))
    fmt.Println(CountChar("     ", ' ')) //The first argument contains space and tabulation.
    fmt.Println(CountChar("The 7 deadly sins", '7'))
}

And its output :

$ go run .
