Convert a string to char in c++

  • 772

I have this structure and I need a data entry in the name field, but I have that data in a string.

typedef struct cliente{
    int cedula;
    int numCuenta;
    char nombre[100];
    cliente *izq, *der;
}cliente;
c++

    std::stringhas a method called c_str()that returns a pointer of type const char*to its internal memory.

    Copying the string to a char*is something that can be done with the function strcpy:

    std::string cadena = "hola mundo";
char buffer[100];
strcpy(buffer,cadena.c_str());
std::cout << buffer;

    By the way, C++ is not C . The syntax people will expect in C++ is this:

    struct cliente{
    int cedula;
    int numCuenta;
    char nombre[100];
    cliente *izq, *der;
};

    Note that I have removed typedef. This layout works in C++ exactly the same as the code you've put in your example.

  2. according to it says Convert a string to char in c++ I made this small code that served me for this purpose

    #include <iostream>

using namespace std;


int main(){

    char c[6]="ii ii";
    string letra;
    char vasinga[5];
    string v="bb bb";

    letra=c;
//    vasinga[5]==v;
    cout<<letra<<endl;

    for(int t=0; t<5; t++){

        vasinga[t]=v.at(t);

    }
    for(int t=0; t<5; t++){
        cout<<vasinga[t];
    }

    return 0;
}
