C++ code after a for loop doesn't execute - c++

Question

It's a bit weird to me that the code after a for loop doesn't execute but the compiler doesn't raise any warning:
#include <iostream>
#include <iterator>
bool isVowel(char ch)
{
char vowels[]{"aeiouAEIOU"};
char *p = std::find(std::begin(vowels), std::end(vowels), ch);
if (p != std::end(vowels))
{
std::cout << ch << " is a vowel" << '\n';
return true;
}
else
{
std::cout << ch << " is not a vowel" << '\n';
return false;
}
}
int main()
{
char name[]{"MollieU"};
int numVowels{0};
std::cout << name << '\n';
int length{std::size(name)};
for (char* ptr{name}; ptr < (name + length); ++ptr)
{
if (isVowel(*ptr))
++numVowels;
}
std::cout << name << " has " << numVowels << " vowels." << '\n';
return 0;
}
It has outputs like:
MollieU
M is not a vowel
o is a vowel
l is not a vowel
l is not a vowel
i is a vowel
e is a vowel
U is a vowel
But std::cout << name << " has " << numVowels << " vowels." << '\n'; is never run. Whatever code I put after the loop is never run. I am not sure if return 0 is run or not, but the file is compiled successfully. I am using g++ -std=c++2a on osx.

Answer 1

Try to use the following:
int length { std::size(name) - 1 };
