Then pointers do pass by value instead of by reference in caller?

Are you saying that the [0] points to 'A', at the start of the array? Does that mean that since 'D' is 3 characters away from 'A', the ptr would use [3]?

For example:
ptr = &alphabet [3];

Sorry to keep you waiting for an answer. Honestly, I'm not sure how to set ptr to point to an individual letter in the array. At first I thought it would have to do with converting the letter to...

const char alphabet [26] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

I have a character pointer question.

Given a char pointer called ptr (i.e. char *ptr) and the alphabet array (const char alphabet[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"), how do I make ptr point to the...

I have a question about pointers. What do they enable passing VARIABLES to FUNCTIONS by (ex. value, reference)?

I'm not able to run the code, but I just need to verify that it works in the same way strlen() does.

Here's what I thought would work:


int string_length( char str[ ] )
{
int count = 0;

while ( string[count] != '\0' )
++count;

I need the correct C code for this function string_length, to calculate the number of characters in a string and return the answer as an int (without counting the null terminator '\0').

I've typed up this code below, but need to find Z. Do I need printf to show what z is and if so, how would I implement it?

int n, z;

z=1000
for (n=0; n<100; n+=100)
{
z++;

I was wondering if "Less than or equal to" is symbolized as <= or <== in code and how this statement could be translated into code:

If A is less than or equal to B and A is equal to G, then print...
