string to char* c++ code example

Example 1: string to char array c++

std::string myWord = "myWord";
char myArray[myWord.size()+1];//as 1 char space for null is also required
strcpy(myArray, myWord.c_str());

Example 2: convert string to char c++

// "std::string" has a method called "c_str()" that returns a "const char*"
// pointer to its inner memory. You can copy that "const char*" to a variable
// using "strcpy()".

std::string str = "Hello World";
char buffer[50];

strcpy(buffer, str.c_str());

std::cout << buffer;	//Output: Hello World

Example 3: COnvert string to char * C++

// CPP program to convert string 
// to char array 
#include <bits/stdc++.h> 
  
using namespace std; 
  
// driver code 
int main() 
{ 
    // assigning value to string s 
    string s = "geeksforgeeks"; 
  
    int n = s.length(); 
  
    // declaring character array 
    char char_array[n + 1]; 
  
    // copying the contents of the 
    // string to char array 
    strcpy(char_array, s.c_str()); 
  
    for (int i = 0; i < n; i++) 
        cout << char_array[i]; 
  
    return 0; 
}

Example 4: char to string c++

std::cout << std::string(1, c) << std::endl;

Example 5: C++ int to char*

std::string s = std::to_string(number);
char const *pchar = s.c_str();  //use char const* as target type

Example 6: why convert char* to string c++

char *cStr = "C++";
std::string Str = std::string(cStr);
