How to change the case to a string so when I run the script the the string instead of the case number is shown?

m=menu('select shape:', 'triangle','square','pentagon','hexagon','heptagon','octagon')
switch m
    case 1
         n=3
        angle=(n-2)*180
    case 2
        n=4
        angle=(n-2)*180
    case 3         
        n=5
        angle=(n-2)*180
    case 4
        n=6 
        angle=(n-2)*180
    case 5
        n=7
        angle=(n-2)*180
    case 6
        n=8
        angle=(n-2)*180

end

fprintf('A %-5.2f has %-5.2f sides and %-5.2f degrees\n',m,n,angle)

>> Untitled

m =

     1

n =

     3

angle =

   180

A 1.00 has 3.00 sides and 180.00 degrees

I believe you want:

fprintf('A %s has %d sides and %-5.2f degrees\n',m,n,angle)

You know you're stuff. Thanks

As always, my pleasure.

Hi Frank_m

Use the following code

clc
clear

m=menu('select shape:', 'triangle','square','pentagon','hexagon','heptagon','octagon');
switch m
    case 1
        m = 'triangle'
        s = 1;
        n=3
        angle=(n-2)*180
    case 2
        m = 'square'
        s = 2;
        n=4
        angle=(n-2)*180
    case 3
        m = 'pentagon'
        s = 3;
        n=5
        angle=(n-2)*180
    case 4
        m = 'hexagon'
        s = 4;
        n=6
        angle=(n-2)*180
    case 5
        m = 'heptagon'
        s = 5;
        n=7
        angle=(n-2)*180
    case 6
        m = 'octagon'
        s = 6;
        n=8
        angle=(n-2)*180

end

fprintf('A %-5.2f has %-5.2f sides and %-5.2f degrees\n',s,n,angle)

no good.

m=menu('select shape:', 'triangle','square','pentagon','hexagon','heptagon','octagon'); 
switch m 
    case 1 
        m = 'triangle' 
        s = 1; 
        n=3 
        angle=(n-2)*180 
    case 2 
        m = 'square' 
        s = 2; 
        n=4 
        angle=(n-2)*180 
    case 3 
        m = 'pentagon' 
        s = 3; 
        n=5 
        angle=(n-2)*180 
    case 4 
        m = 'hexagon' 
        s = 4; 
        n=6 
        angle=(n-2)*180 
    case 5 
        m = 'heptagon' 
        s = 5; 
        n=7 
        angle=(n-2)*180 
    case 6 
        m = 'octagon' 
        s = 6; 
        n=8 
        angle=(n-2)*180
end
fprintf('A %-5.2f has %-5.2f sides and %-5.2f degrees\n',s,n,angle)

A 1.00 has 3.00 sides and 180.00 degrees

[Frank_m]

This is what I want from the fprint: "A shape has n sides and angle degrees"

[Frank_m]

example: "A triangle has 3 sides and 180 degrees"

Change the last line to the following line

fprintf('A %s has %-5.2f sides and %-5.2f degrees\n',m,n,angle)%
