The c_str() method returns a pointer to a null-terminated sequence of characters for a string object. We can copy these characters in our char array using strcpy() function. See the below example. #include <iostream> #include <cstring> using namespace std; void print_char_array(char ...
CString filepath = "C:\testing.txt";char cContent[3000];string sContent = "";fstream file_op(filepath,ios::in);while(file_op.getline(cContent,3000)){sContent += cContent;}file_op.close();sContent.erase(sContent.end()-1);
To use CString with copying while sending. Use function void send(int code, const String& contentType, const char *content, bool nonDetructiveSend = true); // RSMODsuch asrequest->send(200, textPlainStr, cStr);The required additional HEAP is also about 2 times of the CString size ...

Another built-in function included in thestd::stringclass issize, which behaves similarly to the previous method. It takes no arguments and returns the number ofcharelements in the string object. #include<cstring>#include<iostream>using std::cin;using std::cout;using std::endl;using std::str...
