Question

Write in C.

Write a function that takes an array of integers and its size as parameters and prints the two largest values in the array. In this question, the largest value and the second largest value cannot be the same, even if the largest value occurs multiple times. In the first sample, the two largest values are 9 and 8 (even though the value 9 appears twice). In the second sample, all the values are equal and the program recognizes this by printing a special message Array data 1 957283 19 4 Maximum value:9 second largest value: 8 Array data Maximum value: 2 All the values are equal

#include <stdio.h>
   
void maxNextmax(int arr[], int size){
   int max = -1, nextMax = -1, i;
   if(size > 0){
      max = arr[i];
      nextMax = -1;
   }
   for(i = 1;i<size;i++){
      if(max == arr[i]){
         continue;
      }
      else if(max < arr[i]){
         if(nextMax < max){
            max = nextMax;
         }
         max = arr[i];
      }
      else{
         if(nextMax < arr[i]){
            nextMax = arr[i];
         }
      }
   }
   printf("\nMaximum value: %d\n",max);
   if(nextMax == -1){
      printf("All the values are equal");
   }
   else{
      printf("Second largest value: %d\n",nextMax);
   }
}

int main()
{
   int arr[10];
   int i, size = 10;
   printf("Array data\n");
   for(i = 0;i<size;i++){
      scanf("%d",&arr[i]);
   }
   maxNextmax(arr,size);
    return 0;

}
