String characteristics

In my previous blog, I have given you an introduction to strings.Today I will discuss on some string characteristics or you can say,"string operations".

String size( )

If you want to find the length of any string, then its syntax is as follows:

 str.length( );

String length( )

If you want to find the length of any string, then its syntax is as follows:

 str.length( );

String capacity( )

If you want to find the capacity of any string, then its syntax is as follows:

str.capacity( );

Maximum size( )

If you want to size the maximum size of any string, then its syntax is as follows:

str.max_size( );

String empty or not

If you want to check whether the string is empty or not,then its syntax is as follows:

(str.empty?"yes":"no") ; (it is same as conditional operator)

So, to implementation of these operations is as follows:

Source code

#include<iostream>

#include<string.h>

using namespace std;

main()

{

string s1;

cout<<"Enter any string:";

getline(cin,s1); // syntax for getting the input of string

cout<<"Size="<<s1.size()<<endl<<endl;

cout<<"Length="<<s1.length()<<endl<<endl;

cout<<"Capacity="<<s1.capacity()<<endl<<endl;

cout<<"Maximum size="<<s1.max_size()<<endl<<endl;

cout<<"Empty="<<(s1.empty()?"yes":"no")<<endl<<endl;

}

Output
