Expected Function

    ...
}

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("   ", ' '))
	fmt.Println(CountChar("The 7 deadly sins", '7'))
