Write a subroutine that finds the maximum number in an array

Write a subroutine that finds the maximum number in an array. The array contains 8-bit signed numbers. The first element of the array is the size. Register R0 is a call by reference pointer to the array. The maximum value in the array is returned in Register R0.

Solution

Code:

#include <stdio.h>
main(){
   int array[100], *maximum, size, c, location = 1;
   printf(\"Enter the number of elements in array\ \");
   scanf(\"%d\",&size);
   printf(\"Enter %d integers\ \", size);
   for ( c = 0 ; c < size ; c++ ){
       scanf(\"%d\", &array[c]);
   }      
   maximum = array;
   *maximum = *array;
   for ( c = 1 ; c < size ; c++ ){
       if ( *(array+c) > *maximum ){
           *maximum = *(array+c);
           location = c+1;
       }
   }
   printf(\"maximum element is %d\", *maximum);
   return 0;
}

Output:
