Retain all initial even value elements, add all odd values with 1

Using random number generator, generate ten integer values in the form of 1-D array. Store it in a variable named A2Q10. How to retain all initial even value elements, add all odd values with 1? Now I know A2Q10 = randi([1 10],1,10) is to generate. But how to form a new 1-D array to only add 1 to odd value elements from the generated 1-D array. Please help me!

Hint: Read about mod. If mod(x,2) is 1 then x is odd.

mod(4,2)     % even number 

ans = 0

mod(5,2)     % odd number 

ans = 1
