Question

please help me by matlab

5.2) Develop a program that prompts the user for three numbers. Once received, print the multiplication of the first two numbers. Use the third number as the quantity of decimal places to print. 5.3) Develop a program that prompts the user for two numbers and a calculation operator (+,-/or *). Once received, use appropriate IF STATEMENTS to complete the calculation guided by the following rules: Addition Subtraction Division Multiplication Print to output to three decimal places.

vams. mx 1 format long 2 first = input('first :'); $prompting inputs 3 second = input('second :'); 4 third = input('third :'); 5 multiply = first * second; 6 fprintf('Multiplication of two numbers is %. *f', third, multiply); 7 % using third number as quantity of decimal places to pring

source code:

format long
first = input('first :'); %prompting inputs
second = input('second :');
third = input('third :');
multiply = first * second;
fprintf('Multiplication of two numbers is %.*f',third,multiply);
% using third number as quantity of decimal places to pring

one = input('First number : '); %prompting inputs
two = input('Second number :');
opr = input('Enter operator :');
if( opr == '+') %checking with if statemets
disp(one+two);
elseif( opr == '-')
disp( one-two);
elseif( opr == '/')
disp( one/two)
elseif( opr == '*')
disp( one*two);
else
disp('Choose correct operator')
end
