Write a function that returns the largest value stored in an array of int

Demo Code

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define SIZE 10//from  w ww  .  j  a  v a  2s  .  c o m

int max_int(int *arr, int arr_size); // function prototype

int main(void)
{
  int test[SIZE];

  srand(time(NULL)); // seed random number generator
  
  // initialize test array with random ints between 0 and 99
  for (int i = 0; i < SIZE; i++)
    test[i] = rand() % 100;

  printf("The maximum of ");
  for (int i = 0; i < SIZE; i++)
    printf("%d ", test[i]);
  printf("is: %d\n", max_int(test, SIZE));

  return 0;
}

int max_int(int *arr, int arr_size){
  int max = arr[0];
  for (int i = 1; i < arr_size; i++){
    if (arr[i] > max)
      max = arr[i];
  }
  return max;
}
