In C++, the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type...
The output of this example will be: Hello, World! Use theStringBuilderClass to Convert the String Array to String in C# In C#, theStringBuilderclass provides an efficient and flexible solution for concatenating string array elements into a single string, especially when dealing with dynamic or fre...

#include<iostream>#include<string>intmain(){inti=0;charc_arr[]="DelftStack";intlen=sizeof(c_arr)/sizeof(char);std::string str="";while(i<len){str=str+c_arr[i];i=i+1;}std::cout<<str;return0;} In the above example, we use thewhileloop instead of theforloop to carry out ...
Thus, an array of a class type is also known as an array of objects. An array of objects is declared in the same way as an array of any built-in data type. Syntax: class_name array_name [size] ; Example: #include<iostream>classMyClass {intx;public:voidsetX(inti){ x = i; }in...
In this approach, we are usingstd::copy()method to copy all characters of the string into the char array. Method 4: Using string::copy() #include<iostream>usingnamespacestd;intmain(){stringstr;cout<<"Enter a string \n";getline(cin,str);//create an char array of the same sizecharar...
