Get character array address then convert to pointer char

Question

I convert my string and bytearray to char array.

char nameData[90];
char passData[90];
strcpy(nameData, name.toStdString().c_str()); //string
strcpy(passData, pass.data()); //bytearray

Now I need to get the address of the nameData and passData to set it as a pointer? Or is there an easy to convert the string and bytearray to char pointer?

I need to convert it to char pointer to store it to a file.

Answer 1

I think just use the type conversion would be ok. eg char* pNameData = (char*) nameData . In fact you can use the nameData directly as char* pointer in C or C++.

Answer 2

I need to get the address of the nameData

A char pointer points to a char. It doesn't point to an array strictly speaking.

Your array is an array of char objects however. So, I take it that you actually mean "I need to get the address of the first character of nameData" .

It's quite simple. An array is implicitly convertible to a pointer to the first element of the array. In fact, the array name decays to this pointer whenever the value is used. So, simply assign the pointer:

char* pointer = nameData;

I need to convert it to char pointer to store it to a file.

You probably don't even need the pointer variable. Simply pass the array directly to the function that takes the character pointer argument.
