This function reduces the capacity of the string and makes it equal to its size.
Syntax
Consider a string str. Synatx would be:
Example
str.shrink_to_fit();
Parameter
It does not contain any parameter.
Return value
It does not return any value.
Example 1
Let's see the simple example.
Example
#include<iostream>
using namespace std;
int main()
{
string str="C++ Programming";
cout<<str.capacity()<<'\n';
str.shrink_to_fit();
cout<<str.capacity();
return 0;
}
Output:
In this example, shrinktofit function is applied to the string so that capacity of string becomes equal to the size of string.
Example 2
Let's see another simple example.
Example
#include<iostream>
using namespace std;
int main()
{
string str="Computer is my favorite subject";
cout<<"Initial string value is :"<<str<<'\n';
str.resize(24);
cout<<"After resizing,string value is :"<<str<<'\n';
str.shrink_to_fit();
cout<<"capacity of the string is :"<<str.capacity()<<'\n';
cout<<"size of the string is :"<<str.size();
return 0;
}
Output:
Output
Initial string value is: Computer is my favorite subject
After resizing, string value is: Computer is my favorite
capacity of the string is :24
size of the string is :24
