C++ Vector resize()

It modifies the size of the vector to the specified value

Size changed to 4 and new value is

Syntax

Consider a vector v. Syntax would be:

Parameter

n : It is the new vector size.

val : If n is greater than the current vector size, then value(val) is inserted in the added space.

Return value

It does not return any value.

Example 1

Let's see a simple example when n is less than the current vector size.

Output:

     Initial elements are: 1 2 3 4 5 6 7 8 9 10 
After resizing its size to 5, elementsare: 1 2 3 4 5 

Example 2

Let's see a simple example n is greater than the current vector size.

Output:

Elements of v1 are :java C C++ java C C++ .Net .Net
