Program to Convert String to Char Array in C++
String to Char Array :
String is defined as the sequence of characters while char array is defined as the array of characters.Here we will convert string into character array.
How to Convert String to Char Array in C++ :
In general, String can converted into char array by using loop or also by other method.
Below are the two techniques to convert string to char array in C++ :
Method 1 :
#include<iostream>
#include<bits/stdc++.h>
using namespace std;
int main() {
string str = "PrepInsta";
int n = str.length(); // size of string
char* arr = new char[n+1]; //declaring a character array
for(int i=0;i < n;i++){
arr[i] = str[i];
}
arr[n] = '\0';
cout< < "The character array is : "< < arr;
return 0;
}
Output :
The character array is : PrepInsta
In the above program, we traverse the string using for loop and store the particular character of string into the char array.
Method 2:
#include<iostream>
#include<bits/stdc++.h>
using namespace std;
int main() {
string str = "PrepInsta";
char* arr = &str[0]; //declaring a character array and assign it with address of string
cout<<"The character array is : "< < arr;
return 0;
}
Output :
The character array is : PrepInsta
In the above program, we directly assign the address of 1st character of string to a pointer of char array.
