Get a single character from a char* in C

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.
}

Answer 2

Knowing the length of the char array, you can cycle through it with a for loop.

for (int i = 0; i < myStringLen; i++)
{
     if (a[i] == someChar)
        //do something
}

Remember, a char * can be used as a C-Style string. And a string is just an array of characters, so you can just index it.
