Convert char array to string use C

Question

I need to convert a char array to string. Something like this:

char array[20];
char string[100];

array[0]=\'1\';
array[1]=\'7\';
array[2]=\'8\';
array[3]=\'         


        

Answer 1

Assuming array is a character array that does not end in \0, you will want to use strncpy:

char * strncpy(char * destination, const char * source, size_t num);

like so:

strncpy(string, array, 20);
string[20] = '\0'

Then string will be a null terminated C string, as desired.
