How to convert a char array to a string in Embedded Wizard

Question

Hello EmWi community,

is there a way to convert a character array to a string variable inside the EmWi-IDE?

Answer 1

Hello,

create a string with a length corresponding to the number of characters within the array and then loop through the array elements and assign the characters one by one to the string. The following is the code:

// The array containing the characters to compose the string
// and the number of characters to pick from the array.
array char theArray[...];
var int32  noOfChars = ...;

// Create a new string with length matching exactly the number
// characters you want to copy from the array
var string theString = string( ' ', noOfChars );
var int32  i;

// Loop through the array and copy the characters into the 
// string
for ( i = 0; i < noOfChars; i = i + 1 )
  theString[i] = theArray[i];

Hope it helps you further.

Best regards
