A string is not the same type as a number in MATLAB. One is type char, the other is (by default) type double. To store variables of two different types in one array, you need to use cell arrays. See http://www.mathworks.com/help/matlab/matlab_prog/what-is-a-cell-array.html
Try
b{c,1} = input('What''s your Name:','s');
b{c,2} = input('What''s your first score :');
b{c,3} = input('What''s your second score :');

Use the num2str function to convert the numeric iteration variable that's changing each time through the for loop to a char and construct a string to pass to the input function as follows:
for c = 1:a
str1 = ['What''s the name (',num2str(c),') :']; % build strings
str2 = ['What''s his/her value (',num2str(c),') :'];
b{c,1} = input(str1,'s');
b{c,2} = input(str2);
end
