## 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 |
||||||
|
|
||||||
|
```go |
||||||
|
func CountChar(str string, c rune) int { |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a possible program to test your function: |
||||||
|
|
||||||
|
```go |
||||||
|
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 : |
||||||
|
|
||||||
|
```console |
||||||
|
$ go run . |
||||||
|
3 |
||||||
|
0 |
||||||
|
1 |
||||||
|
1 |
