Question 13

The subroutine LOCATE finds the index of the first occurrence of a character in a string, using 0-based indexing.

For example, LOCATE('Database', 'a') would return 1.

Four variables are initialized as follows:

continent ← 'South America'
country ← 'Argentina'
capital ← 'Buenos Aires'
highlight ← 'Iguazu Falls'

The variable y is assigned a value using the statement:

y ← LOCATE(highlight, 'u')

What value is assigned to y?
