What is a function definition?3. Explain function overloading.4. Code two function declarations which demonstrate function overloading.hi, i need to modify the class definition by adding the necessary data mem and proto. for the coin function given in the class. that function (coin()), returns the num of coins that exist at any time in the program. I'm unsure of how to implement it, please help me implement the function and explain!! in C++ please and thank youWrite a C# program to define a function that takes parameters and also returns something. Also, make a call to your function inside the main function. Note: The return type should not be void.
- I am learning c++, and I get confused. I meet three questions, and one is asking to write a function header for a function named distance; the second question is to write the prototype for a function named distance, and the third question is to write a function call for a function named distance. I am wondering how to write different functions for these three questions? What are the differences between them? I am so confused.Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows:dB= log10P2/P1Where P2 is the power level being measured, and P1 is some reference power level. Write a c++ programe contain function that calculates the level. The function’s prototype is as follows:double dBCalculator (double P1, double P2);Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 2 Watt steps. You can assume that the reference power P1 is 1 Watt.I need help in solving this question Question 10 Given the code segment below, what should be the data type of the formal parameter in the function prototype of func(), given the call from main()?Note that function prototypes need not include the identifier (name of the parameter), so do NOT put any variable name in your answeIf the accessing is wrong, answer INVALID (in all capital letters). void func( ______ ); int main() { double aData[6][4]; func(aData[6]); return 0; }
- I could really use help with void-user defined, value-returning functions. here's my Instructions for my C++ program: The function printGrade in Example 6-13 is written as a void function to compute and output the course grade. The course score is passed as a parameter to the function printGrade. Rewrite the function printGrade as a value-returning function so that it computes and returns the course grade. (The course grade must be output in the function main.) Also, change the name of the function to calculateGrade.The function printGrade has been posted below for your convenience. void printGrade(int cScore){cout << "The course grade is: "; if (cScore >= 90) {cout << "A." << endl; } else if (cScore >= 80) {cout << "B." << endl;} else if(cScore >= 70) {cout << "C." << endl;} else if (cScore >= 60) {cout << "D." << endl; } else {cout << "F." << endl; } I don't understand how to program a void function. It…9-Given the code segment below, what should be the data type of the formal parameter in the function prototype of func(), given the call from main()? Note that function prototypes need not include the identifier (name of the parameter), so do NOT put any variable name in your answer. Remove any space in your answer. If the accessing is wrong, answer INVALID (in all capital letters). void func( ______ ); int main() { double aData[6][4]; func(&aData[4]); return 0; }Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
- Assume that the declarations for two functions look as follows: int Function1(double x); 2.void Function2(double x); Give some sample code that would show how each function could be used.Answer the following as completely as possible in your own words:1. What is a function declaration?2. What is a function definition?3. Explain function overloading.4. Code two function declarations which demonstrate function overloading.In C++, Given the following function prototype: void testDefault(int a, int b = 7, char z = '*'); Indicate if each of the following function calls are valid or invalid a) testDefault(5); b) testDefault(); c) testDefault(6, '#'); d) testDefault(0, 0, '?');
