Answer to Question #233120 in C++ for haha

Question

Construct function prototypes that match the following descriptions:

i) ab () takes no arguments and has no return value.

ii) start() takes an int argument and returns a float.

iii) mk() takes two type double arguments and returns a double.

iv) func6() returns an int and takes three arguments. The first and third arguments are of

type double. The second argument is of type int.

v) func4() returns a char and takes one argument that is also of type char.

Answer 1

#include <iostream>
#include <string.h>
using namespace std;
//Prototype
//ab() takes no arguments and has no return value
void ab();
//start() takes an int argument and returns a float.
float start(int );
//mk() takes two type double arguments and returns a double
double mk(double, double);
/*
func6() returns an int and takes three arguments. The first and third arguments are of
type double. The second argument is of type int.
*/
int func6(double, int, double);
//func4() returns a char and takes one argument that is also of type char.
char func4(char);
