How to take value from function and put it into disp script?

My task is to "display the words: 'The ball hits the ground at a distance of X meters', where X is the hitDistance from the function throwBallFunc." (I have written the throwBallFunc).

So far, I have disp( ' The ball hits the ground at a distance of %d meters '); which is not working. How do I write it so that I can get the value of X aka hitDistance from the function throwBallFunc that I created? Thank you!

Use:

sprintf( ' The ball hits the ground at a distance of %d meters ',X)

or:

fprintf( ' The ball hits the ground at a distance of %d meters ', X)

instead, depending on what you want to do.

I have to use the disp function. Any way I can do it with that?

Yopu didn’t say that.

Try this:

disp([' The ball hits the ground at a distance of ' num2str(X) '  meters '])

That worked when I tested it. It uses the MATLAB concatenation operator [] to create one character array from three character arrays.
