C++ How to remove 0 values from array without using vector

As the title says I want to remove the elements in my array that contain 0.

When the user prompt an integer that's the same the program rejects the user input and will automatically put a 0 there instead but I want it to be removed.

Here is my current output in an array of 20

25     35     50     23     95     55      9     85     45      0     
97     56      0     33     75      0    101     86    100      0 

and here is my desire output with the same user prompt

25    35    50    23    95   55    85    45    97   
56    33    75    86   100
