In C++, a function or method can accept multiple arguments which can be used inside the function body to perform some action or return some result. To use multiple arguments in a function or method, you need to declare the arguments inside the parentheses separated by commas.
Here is an example of a function that accepts three integer arguments and returns their sum:
int sum(int a, int b, int c)
{
int result = a + b + c;
return result;
}
To call this function with three arguments, you simply pass the values separated by commas:
int total = sum(1, 2, 3);
// total = 6
Here's an example of a method in a class that accepts two integer arguments and updates the value of a class member variable:
class MyClass {
public:
void add(int a, int b) {
int result = a + b;
myValue += result; // assume myValue is a class member variable
}
private:
int myValue = 0;
};
MyClass obj;
obj.add(2, 3); // myValue now equals 5
In summary, to use multiple arguments in a function or method in C++, you simply declare the arguments separated by commas inside the parentheses and use them in your function or method body.
