I don't understand how the time complexity for this algorithm is calculated

I hope this helps . The reason why this is O(n) is because j is not set back to 0 in the body of the for loop.
Indeed if we take a look at the body of the for loop, we see:
while ( (j<N-1) && (A[i]-A[j] > D) )
    j++;

int j=0;
for (int i=0; i<N; i++) {
    while ( (j<N-1) && (A[i]-A[j] > D) )
        j++;
    if (A[i]-A[j] == D) 
        return 1;
}

Banker's algorithm calculated time complexity

Any of those help The Banker's algorithm is used to determine if all requests for resources can be satisfied without leading to a deadlock. , The below part introduces (n*m) time complexity
for I = 1 to N do // *n times
      if ((not FINISH[i]) and
         NEEDi <= WORK) then // *m times, if it's an array search

WORK = WORK + ALLOCATION_i; // also O(m) operation, vectors addition

Time Complexity of an algorithm : How to decide which algorithm after calculated the time

will help you He said that because 10N + 8 is a linear equation. If you plot that equation you get a straight line. Try typing 10 * x + 8 on this website (function graphs) and see for yourself.

Is time complexity of an algorithm calculated only based on number of times loop excecutes?

wish help you to fix your issue First note that in Big-O notation there is nothing such as O(n/2) as 1/2 is a constant factor which is ignored in this notation. The complexity would remain as O(n). So by modifying your code you haven't changed anything regarding complexity.
In general estimating the number of times a loop is executed with respect to input size and the operation that actually is associated with a cost in time is the way to get to the complexity class of the algorithm.

Understand time complexity of algorithm to generate strings

hop of those help? I have an algorithm that takes as input 3 strings, with a strcat concat for each letter like this: , There are a couple of issues here.

it should still fix some issue @blazs's answer seems correct. If that helps you understand, that's great. Here is an answer for visual learners like myself...
