Question

Is there a way to traverse character by character or extract a single character from char* in C?

Consider the following code. Now which is the best way to get individual characters?
Suggest me a method without using any string functions.

char *a = "STRING";

Answer 1

Another way:

char * i;

for (i=a; *i; i++) {
   // i points successively to a[0], a[1], ... until a '\0' is observed.
}
