With this little code, I have 2 issues, both surrounding the loop of mine.
I have a list of students' ages, and I want to input a value and loop all students lineary until it matches a student.
The other issue I found was that even if the value inside the loop is equal to what I'm checking, it wouldn't trigger my if statement. I tested this by searching for Age 1 while the first student in the list was also Age 1.
Here's my full code with 2 debug lines and a print screen of my run of it.
Apologies for not commenting my code yet.

}
void store(string _name, int _age)
{
name = _name;
age = _age;
}
};
int LinearSearch(Student* studentArray, int age)
{
for (int i = 1; i <= 14; i++)
{
cout << "DEBUG AGE: " << age << endl;
cout << "DEBUG: Searched student: " << i << " His age was: " << studentArray[i].age << endl;
if (studentArray[i].age = age)
