Can someone help me how to make number of input like above?

You need a cell array since they can have different lengths. Use braces instead of parentheses: b{c,1}

Use sprintf() instead.

Hi...
This may help you and it will take both string&character but it can store a single character.
a= input ('The number of participant :'); for c=1:a x=input('Whats the name ','s'); b(c)=x; b(c)= input('Whats his/her value '); end %%FOR DISPLAY for c=1:a disp(b(c)); disp(d(c)); end
