"I am a string" 'so am I' "344" In this example, the 344 string is an array of characters. The number 344 is a value that Siebel eScript can use in a numeric calculation. To create a string data type, you use the String constructor in the following type of expression: ...
Reports the zero-based index of the first occurrence of the specified Unicode character in this string. A parameter specifies the type of search to use for the specified character. IndexOf(Char) Reports the zero-based index of the first occurrence of the specified Unicode character in this st...

c = size(A) c =1×21 30 s = size(str) s =1×21 1 To return the number of characters instr, use thestrlengthfunction. n = strlength(str) n = 30 Convert Cell Array Convert a cell array of character vectors to a string array. ...
We iterate through the string with the for loop. The size of the string is determined with thestrlenfunction. Theordfunction returns the ASCII value of a character. We use the array index notation to get a character. $ php array_of_chars.php ...
