Question

Im trying to create a function in C where it takes an array and size and returns the largest absolute value in the array (either negative or positive). Any help would be greatly appreciated!

Ex: if the array is { -2.5, -10.1, 5.2, 7.0}, it should return -10.1

Ex: if the array is {5.1, 2.3, 4.9, 1.0}, it should return 5.1.

double getMaxAbsolute(double array[], int size)
{
    double max = array[0];
   double abs[size];
   for (int i = 0; i < size; i++) {
      
        if ( array[i] >= 0){
        abs[i] = array[i];
        }
        else if (abs[i] < 0){
           abs[i] = - array[i];
       }

       if (abs[i] > max)
       {
            max = array[i];
          
        }
   }

   return max;
}

#include <iostream>
#include <cmath>

using namespace std;

double getMaxAbsolute(double array[], int size)
{
double max = array[0];
for (int i = 1; i < size; i++)
{
if(fabs(array[i])>fabs(max))
{
max=array[i];
}
}
return max;
}

int main()
{
double array[4]= {-55.1, 2.3, 4.9, -110.0};
cout<<getMaxAbsolute(array,4);
return 0;
}
