This code:
Module Module1
Sub Main()
' Our input string.
Dim animals As String = "cat, dog, bird"
' See if dog is contained in the string.
If Not animals.IndexOf("dog") = -1 Then
Console.WriteLine(animals.IndexOf("dog"))
End If
End Sub
End Module
Return start position 5 in string
But how to return index of string so:
for cat = 1
for dog = 2
for bird = 3
Looking at your desired output it seems you want to get the index of word in your string. You can do this by splitting the string to array and then finding the item in an array using method Array.FindIndex:
Dim animals = "cat, dog, bird"
' Split string to array
Dim animalsArray = animals.Split(New String() {",", " "}, StringSplitOptions.RemoveEmptyEntries)
' Item to find
Dim itemToFind = "dog"
' Find index in array
Dim index = Array.FindIndex(Of String)(animalsArray, Function(s) s = itemToFind)
' Add 1 to the output:
Console.WriteLine(index + 1)
Above code returns 2. For cat you would get 1 and for bird the result would be 3. If there is no item in the array the output would be 0
c,arrays,segmentation-fault,initialization,int
In your code, int i is an automatic local variable. If not initialized explicitly, the value held by that variable in indeterministic. So, without explicit initialization, using (reading the value of ) i in any form, like array[i] invokes undefined behaviour, the side-effect being a segmentation fault. Isn't it automatically...

You cannot store key-value pair in array. Use object to store key-value pair. See comments inline in the code. var obj = {}; // Initialize the object angular.forEach(data, function(value, key) { if (value.start_date > firstdayOfWeek && value.start_date < lastdayOfWeek) { if (obj[value.firstname]) { // If already exists obj[value.firstname] += value.distance;...

In my personal opinion, NEVER try to get data from an array within quotes! Always do it outside of quotes; especially in multi-denominational arrays. '$input[$rand_keys[$i]]' should be rewritten as '".$input[$rand_keys[$i]]."' OR '{$input[$rand_keys[$i]]}'. In my opinion it is better to do it outside of quotes instead of using { }. ...

The valid range of indices of an array with N elements is [0, N-1]. Thus instead of for example this loop for (int i=1; i <= n; i++) ^^^^ ^^^^^^ you have to write for ( int i = 0; i < n; i++ ) As you used operator new...
Yes, this bookkeeping with i is usually a sign there should be something better. I came up with: ar =[ { name: "foo1", location: "new york" }, { name: "foo2", location: "new york" }, { name: "foo3", location: "new york" }, { name: "bar1", location: "new york" }, { name:...
You should use the random header. #include <random> std::default_random_engine generator; std::uniform_int_distribution dist(0, 5); int StringIndex = dist(generator); std::string ChosenString = characters[StringIndex]; The above will generate a random index into your array. If you want to limit the range, change the constructor of dist, for example (dist(0,2) would only allow for...

The explode function is being used correctly, so your problem is further up.

Your approach doesn't work because you are using ToString on a DataColumn which has no such overload like DateTime. That doesn't work anyway. The only way with the DataTable was if you'd add another string-column with the appropriate format in each row. You should instead use the DataGridViewColumn's DefaultCellStyle: InvestorGridView.Columns(1).DefaultCellStyle.Format...
