Getting output as an array from while loop

clc
clear all

a=0;
x = input('Enter the number : ')
while x<100
    %%example code
if rem(x,2)==0
    x=x+2;
else
    x=x+1;
end
a=a+1;
format long
b=[a x]
end
c=[1 20; 2 22; 3 24]

I want the output of b as a 2 dimensional array where all the values a and x will be existed as like c.

Here is one of the viable solutions:

a=0;
x = input('Enter the number : ')
ii=0;
while x<100
    ii=ii+1;
if rem(x,2)==0
    x=x+2;
else
    x=x+1;
end
a=a+1;
format long
b(ii,:)=[a x]
end
