Write a function maxmagnitude with two input parameters, that returns the largest-magnitude value. if the inputs are 5 7, the function returns 7. if the inputs are-8-2, the function returns-8. (note: the function does not just return the largest value, which for-8-2 would be -2). though not necessary, you may use the absolute-value built-in math function. use the function in a program that takes two integer inputs, and outputs the largest-magnitude value.

The program to this question can be given as:

Program:

#include<stdio.h> //define header file

//#include<stdlib.h> //define header file  

#include<math.h> //define header file

int MaxMagnitude (int n1, int n2) //define function.

{

 int largest_magnitude_value= 0;

 if (abs(n1) > abs(n2))  

 {  

   // largest_magnitude_value

  largest_magnitude_value= n1;

 }

 else

 {  

   //largest_magnitude_value

   largest_magnitude_value=n2;

 }

 return largest_magnitude_value; //return value.

}

int main()  //define main function  

{

 int n1,n2,x;

 //define variable.

 printf("Enter first number :");

 //message

 scanf("%d",&n1);

 //input first value from user

 printf("Enter second number :");

//message

 scanf("%d",&n1);

    //input second value from user

 x=MaxMagnitude(n1, n2);  

//variable holds function return value

 printf("largest magnitude value  is =%d",x);

 //print value.

 return 0;

}

Output:

Enter first number : 5

Enter second number : 7

largest magnitude value is =7
