Counting the Number of Matches in a String in LabVIEW

[Aashish_M]

Overview
This VI shows two approaches to count a specific character within a string.

Description

This VI shows two different ways to count how many times a character occurs within a string. In a first way, LabVIEW converts the string to a byte array and then indexes through each byte using a For Loop. LabVIEW compares each byte to the *. In a second way, LabVIEW uses a While Loop to iteratively parse through the incoming string. The example uses * as the character to search for.

Requirements
LabVIEW Base Development System (or compatible)

Steps to Implement or Execute Code
1. Run the VI
2. Change the string by adding more characters with *
3. See the change
