Hello. I need to make a pointer char point to a memory location that holds a phrase, in C.
I'm doing this:
char *ptr;
char array[3] = {'o','l','a'};
ptr = &array;
But I do not understand what's wrong, I also do not know how to program in C. Can anyone help? And I can not use the string.h library.
Try this:
char *ptr = "Ola";
In C / C ++, the array name is a pointer to the first array element, so you can do the following:
ptr = array;
Another thing, if you want to save a string in an array of characters, do not forget the '%code%' terminator, otherwise things you do not expect can happen.
char *ptr;
char array[] = {'o','l','a', 'ptr = array;
'};
char outroArray[] = "Ola"; // também funciona
ptr = array;
