[Solved] Identify the issue in this MATLAB code snippet for reading numeric data from a CSV file:fid = fopen('values.csv', 'r'); data = fscanf(fid, '%f,'); fclose(fid); | MATLAB

MATLAB - File I/O

Identify the issue in this MATLAB code snippet for reading numeric data from a CSV file:

fid = fopen('values.csv', 'r');
data = fscanf(fid, '%f,');
fclose(fid);

Afclose(fid) is missing, causing a file handle leak.

BThe file is opened in write mode instead of read mode.

CThe format specifier '%f,' incorrectly expects a comma after every number.

Dfscanf cannot read numeric data from text files.

Step-by-Step Solution

Solution:

Step 1: Analyze format specifier
The format '%f,' expects each number to be followed by a comma, which may not be true for the last number.
Step 2: Consequence
This causes fscanf to fail reading the last number or produce incorrect data.
Step 3: Correct approach
Use '%f' without the comma or use textscan for CSV files.
Final Answer:
The format specifier '%f,' incorrectly expects a comma after every number. -> Option C
Quick Check:
Format specifiers must match data layout exactly [OK]

Quick Trick: Avoid trailing commas in fscanf format specifiers [OK]
