Question
Chapter 13, Problem 1E
Program Plan Intro
- Include the necessary header files into program.
- Declare the “typedef” variable in return type of “integer”.
- Define the function named “testFunction()” which returns “1” in return type of integer.
- Define the main method.
- Define the function.
- Declare the object for “FunctionPtr”.
- Call the “testFunction” function and store the result in “objPtr”.
- Print the result on screen.
Expert Solution & Answer
Program Description Answer
The following program is demonstrates the definition of “typedef” variable which represents a pointer to a function.
Explanation of Solution
Program:
//Include required header files
#include <stdio.h>
/*Definition of typedef function*/
typedef int(*FunctionPtr)(void);
/*Function definition*/
int testFunction(void)
{
//Return statement
return 1;
}
//Main funciton
int main(void)
{
//Function definition
int testFunction(void);
//Object declaration
FunctionPtr objPtr;
//Function is called by pointer
objPtr = testFunction;
//Print statement
printf("%i\n", objPtr());
//Return statement
return 0;
}

Indicate whether the following is true or false:Only pointers and references are permissible for use with dynamically bound virtual functions.
Is that correct?Pointers or references are required for dynamically bound virtual functions.
Explain, with the use of an illustration, how the background process of invoking inline functions varies from that of calling a normal function.

- Write a function f which takes three pointers to int variables (a, b, c). Then it should:-Set the first variable to the sum of values of the variables (a + b + c).-Set the second variable to difference between maximum and minimum of values ( max(a,b,c) - min(a,b,c) )-Set the third variable to median of a, b, c.For example:if a = 5, b = 10, c = 2Then f(&a, &b, &c) should:Set a to 17 (that is the sum)Set b to 8 (that is max - min = 10 - 2)Set c to 5 (that is the median of 5, 10 and 2) NOTE: You are already provided a test main which checks your code for evaluation.

The convolution is defined as (f ∗ g)(t) = Z t 0 f(τ )g(t − τ ) dτ for f, g : [0, ∞) → R. The argument function f and g should be passed by pointers. The integral should be approximated by the Riemman sum, i.e., Z b a f(x) dx = Xn i=1 f(xi) ∆x, where ∆x = b−a n and xi = a + i ∆x. Define the functions func1, func2 and func3, that return sin(x), cos(x) and x 3 respectively. Use these functions to calculate the convolution of f = sin(x), g = sin(x) f = sin(x), g = cos(x) f = sin(x), g = x 3 for t = 2π and n = 1000.arrow_forward

The function should also return the number of ancestors found through an integer pointer.arrow_forward
