How to copy a char pointer into a char array?

Question

So I have a pointer to a char array:

temporaryVariable->arrayOfElements; // arrayOfElements is char*

I would like to copy into my char array declared with square brackets:

char stringArray[MAXIMUM_LINE_LENGTH + 1];

How can I do this?

Solution 1

Use strncpy:

strncpy(stringArray, temporaryVariable->arrayOfElements, sizeof(stringArray));
stringArray[sizeof(stringArray) - 1] = '\0';

Solution 2

this code is also ok.

snprintf(stringArray,MAXIMUM_LINE_LENGTH + 1,"%s",temporaryVariable->arrayOfElements);

I'd also note he could check before hand to see if it would fit if truncating the string is not suitable
