Question

Q7 MATLAB help Create a text file (.txt) containing the name, weight (pounds), and height (inches) of five individuals as shown below. John Elliot 175 67 Monica Lopez 158 65 David Miller 215 71 Janet Anderson 185 72 Jessica Diaz 135 61 Then write a script to read the content of the file using fgetl function and calculate the body mass index (BMI=703*weight/Height2 ) of each individual. The script should print a short 2 sentence showing the name and body mass index of each individual on separate lines in the Command Window. Also make sure to error check opening and closing of the text file.

Answer 1

fileName=input('Enter name of the file: ','s');
f=fopen(fileName,'r');
if f==-1
    error('File could not be opened!!!')
else
    line=fgetl(f);
    while line~=-1
        data=split(line);
        fname=data{1};
        lname=data{2};
        weight=str2double(data{3});
        height=str2double(data{4});
        BMI=703*weight/(height*height);
        fprintf('Name: %s %s\nBMI: %.2f\n',fname,lname,BMI)
        line=fgetl(f);
    end
end
f2=fclose(f);
if f2==-1
    error('File could not be closed!!!')
end
