A simple solution is to just keep a track of the counts of letters (a-z). If any of the counts are 0, then it is not a panagram, else it is.
Simple to understand Python solution below:

from string import ascii_lowercase, punctuation
from collections import defaultdict

def isPanagram(sentence):
  sentence = sentence.lower()
  letterCount = defaultdict(int)
  for letter in ascii_lowercase:
    letterCount[letter] = 0
  for letter in sentence:
    if letter in punctuation:
      continue # Skip special characters / punctuation marks
    letterCount[letter] += 1

  missingLetters = [letter for letter, count in letterCount.items() if count == 0]
  if len(missingLetters) == 0:
    print('The sentence is a panagram!')
  else:
    print('The sentence is not a panagram and is missing the letters: ', missingLetters)


isPanagram('Fox nymphs grab quick-jived waltz.')
isPanagram('The quick fox.')
isPanagram('The five boxing wizards jump quickly.')
isPanagram('The five boxing wizards jump.')

	int alphabet[26] = {0};
	for(char c: s)

	for(int i=0; i<26; i++)
		if(!alphabet[i])
			missing+=((char)(i + add));
	cout << (missing.size() ? missing : "Panagram");
	return 0;
