C++ String Data()

This function copies the characters of the string into an array. It returns the pointer to an array obtained from the conversion of string into array.

Syntax

Consider a string str and pointer p. Syntax would be:

Parameter

This function does not contain any parameter.

Return value

It returns the pointer to an array.

Example 1

#include<iostream>
using namespace std;
int main()
{
	string str ="C++ Strings";
	const char* p =str.data();
	cout<<?String contains :?<<p;
	return 0;
}

Output:

String contains : C++ Strings

This example displays the string using data() function.

Example 2

#include<iostream>
using namespace std;
int main()
{
	string source="1245";
	const char* target=source.data();
	cout<<target;
	return 0;
}

Output:
