Object and Function in C++
Object and Function in C++
Pass and return object from C++ Functions
We can pass objects to a function in a same way as passing regular or normal arguments.
Pass Objects to Function in C++
An object can be passed to a function similar to pass structure to a function. Similarly we can pass the object of other class to a function of different class.
Program of Passing object to function C++
#include <iostream>
using namespace std;
class Student {
public:
double marks;
Student(double m) {
marks = m;
}
};
void calculateAverage(Student s1, Student s2) {
double average = (s1.marks + s2.marks) / 2;
cout << "Average Marks = " << average << endl;
}
int main() {
Student student1(88.0), student2(56.0);
calculateAverage(student1, student2);
return 0;
}
Output
Average Marks = 72
Return Object from a Function in C++
Program of return object from a function
#include <iostream>
using namespace std;
class Student {
public:
double marks1, marks2;
};
Student createStudent() {
Student student;
student.marks1 = 96.5;
student.marks2 = 75.0;
cout << "Marks 1 = " << student.marks1 << endl;
cout << "Marks 2 = " << student.marks2 << endl;
return student;
}
int main() {
Student student1;
student1 = createStudent();
return 0;
}
Output
Marks1 = 96.5 Marks2 = 75
