# basicatoi2
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
- Write a function that simulates the behaviour of the atoi function in Go. Atoi transforms a number defined as a `string` in a number defined as an `int`.
|
||
|
|
|
||
|
|
- Atoi returns `0` if the `string` is not considered as a valid number. For this exercise **non-valid `string` chains will be tested**. Some will contain non-digits characters.
|
||
|
|
|
||
|
|
- For this exercise the handling of the signs + or - does not have to be taken into account.
|
||
|
|
|
||
|
|
- This function will **only** have to return the `int` `nbr`. For this exercise the `error` return of atoi is not required.
|
||
|
|
|
||
|
|
## Expected Function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func BasicAtoi2(s string) int {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
piscine ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
s := "12345"
|
||
|
|
s2 := "0000000012345"
|
||
|
|
s3 := "012 345"
|
||
|
|
s4 := "Hello World!"
|
||
|
|
|
||
|
|
n := piscine.BasicAtoi2(s)
|
||
|
|
n2 := piscine.BasicAtoi2(s2)
|
||
|
|
n3 := piscine.BasicAtoi2(s3)
|
||
|
|
n4 := piscine.BasicAtoi2(s4)
|
||
|
|
|
||
|
|
fmt.Println(n)
|
||
|
|
fmt.Println(n2)
|
||
|
|
fmt.Println(n3)
|
||
|
|
fmt.Println(n4)
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/test$ go build
|
||
|
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
|
12345
|
||
|
|
12345
|
||
|
|
0
|
||
|
|
0
|
||
|
|
student@ubuntu:~/piscine/test$
|
||
|
|
```
