Question

The following four lines of code will not run. Which line has an error?

A.line 1: people -c(teacher, student, administrator)
B.line 2: age-c(35,22,50)
C.line 3: S - sum(people)
D.line 4: M - max(ages)

Answer 1

The error in the code is in line 1, where the assignment operator is incorrect, and the characters are not enclosed in quotes. Additionally, line 3 has a logical error as the 'sum' function cannot be applied to a character vector.

Step-by-step explanation:

The code snippets provided seem to be written in the R programming language. There are a few issues within the provided lines of code:

Line 1: The vector assignment operator in R is '<-', not '-'. Also, the elements of the character vector must be enclosed in quotes. The correct syntax should be people <- c('teacher', 'student', 'administrator').it's defined as 'age' but used as 'ages' in line 4. The corrected line should be ages <- c(35,22,50).Line 3: The 'sum' function does not apply to a character vector. The 'sum' function is used to calculate the sum of numerical values, so this line would not work as intended even with the correct syntax.Line 4: Assuming line 2 is corrected to define 'ages' properly, this line would work, but it should use the '<-' operator for assignment: M <- max(ages).

Therefore, the error is in line 1 with the incorrect use of '-' instead of '<->'. Additionally, line 3 has a logical error as you cannot sum a character vector.
