Convert string to char array in C++
This is a C++ program to Convert string to char array in C++. This can be done in many ways:
Type 1:
Algorithm
Begin
Assign value to string m.
For i = 0 to sizeof(m)
Print the char array.
EndExample Code
#include<iostream>
#include<string.h>
using namespace std;
int main() {
char m[] = "Tutorialspoint";
string str;
int i;
for(i=0;i<sizeof(m);i++) {
str[i] = m[i];
cout<<str[i];
}
return 0;
}Type 2:
We can simply call strcpy() function to copy the string to char array.
Algorithm
Begin Assign value to string s. Copying the contents of the string to char array using strcpy(). End
Example Code
#include <iostream>
#include <string>
#include <cstring>
using namespace std;
int main() {
string str = "Tutorialspoint";
char c[str.size() + 1];
strcpy(c, str.c_str());
cout << c << '\n';
return 0;
}Output
Tutorialspoint
Type 3:
We can avoid using strcpy() which is basically used in c by
std::string::copy instead.
Algorithm
Begin Assign value to string s. copying the contents of the string to char array using copy(). End
Example Code
#include <iostream>
#include <string>
using namespace std;
int main() {
string str = "Tutorialspoint";
char c[str.size() + 1];
str.copy(c, str.size() + 1);
c[str.size()] = '\0';
cout << c << '\n';
return 0;
}Output
Tutorialspoint
