Example 2

medium
What is the result of concatenating 'Score: ' + STRING(95) + '%'?

Solution

  1. 1
    Step 1: STRING(95) converts the integer 95 to the string '95'.
  2. 2
    Step 2: Concatenation joins the three strings: 'Score: ' + '95' + '%'.
  3. 3
    Step 3: Result: 'Score: 95%'.

Answer

'Score: 95%'
String concatenation joins strings end to end. When mixing numbers and strings, the number must be converted to a string first (type casting) to avoid type errors.
