Summary:In this programming tutorial, we will learn different ways to convert a string into a char array in C++. Method 1: Using ‘for loop’ #include<iostream>usingnamespacestd;intmain(){stringstr;cout<<"Enter a string \n";getline(cin,str);//Create an empty char array of the same ...
c_str()); cout<<"String to char array conversion:\n"; for (int i = 0; i < str.length(); i++) cout << arr[i]; return 0; } Copy Output: Enter the string: JournalDev String to char array conversion: JournalDev Copy 2. String to Char Array Conversion in C++ Using for ...
To convert a string to character array in C++, you can directly assign the string to character array, or iterate over the characters of string and assign the characters to the char array, or use strcpy() and c_str() functions. We shall go through each of these approaches with examples. ...
