How can I access a char in string in at specific number?

I tried this code but it is giving me errors. So how can I access a character in a string in kotlin? In java, it can be done by the `charAt()` method.

private fun abc(x: String) {
var i: Int = 0
while (x[i].toString() != "+") {
var y: Char = x[i]
i++
}
}

The beauty of Kotlin is that you can do it in few ways, eg.

1. You can simply access it by index:

while (x[i] != '+') {
i++
}

2. Converting to `CharArray`

val chars: CharArray = x.toCharArray()

while (chars[i] != '+') {
i++
}

3. You can also use idiomatic Kotlin (preferred):

- **forEach**

x.forEach { c ->
if (c == '+') return@forEach
}

- **forEachIndexed** if you care about index

x.forEachIndexed { index, c ->
if (c == '+') {
println("index=$index")
return@forEachIndexed
}
}

In both cases, your character is accessed with `c`

The equivalent of Javas [String.charAt()](

) in Kotlin is [String.get()](

). Since this is implemented as an operator, you can use `[index]` instead of `get(index)`. For example


val firstChar: Char = "foo"[0]

or if you prefer

val someString: String = "bar"
val firstChar: Char = someString.get(0)

Could you please try this method instead?

private fun abc(x: String) {
$p = 1;
do {
$p++
}while (x[p]!= "+")
}
