[amp_mcq option1=”have the same return type” option2=”have the same number of parameters” option3=”perform the same basic functions” option4=”None of the above” correct=”option4″]
The correct answer is: D. None of the above
Overloaded functions are functions that have the same name but different parameters. They are required to have different parameter lists, but they can have the same return type and perform the same basic functions.
For example, the following are overloaded functions:
“`
int add(int a, int b) {
return a + b;
}
int add(int a, int b, int c) {
return a + b + c;
}
“`
The first function takes two parameters and returns an integer. The second function takes three parameters and returns an integer. Both functions perform the same basic function, which is to add two or more integers together. However, they have different parameter lists, so they are considered to be overloaded functions.
It is important to note that overloaded functions cannot have the same parameter list. If two functions have the same name and the same parameter list, they are considered to be the same function, and the compiler will generate an error.
Overloaded functions can be useful when you need to create multiple functions that perform similar tasks but with different parameters. This can help to avoid code duplication and make your code more readable.
