You can't. That's why arrays are known as static data structures, that means you have to assign the size at the compile time only. It is a general practice to take the array size large enough so that it can fullfill expected requirements. Or If you know the concept of dynamic memory allocation then there is a thing known as dynamic array. More famously known as *vectors*(defined in stl) in C++.

for that you can Use Vectors

Use a vector (See http://www.cplusplus.com/reference/vector/vector/) or list (http://www.cplusplus.com/reference/list/list/ ). Vectors are better for indexing, and lists are better for inserting/removing.

Hi! Previously I created a sample program that addresses this case. https://www.sololearn.com/Discuss/2372341/?ref=app
