Question

A function that takes three parameters: an int array, an int n that is the size of the array and an int pointer max that is to assign the maximum value in the array. The function will find and return the index of the first occurrence of the maximum value in the array and assign the maximum value to the pointer. For example, in the array {1, 2, 6, 5, 6, 4, 3, 6, 4}, the maximum value is 6 and the index of the first occurrence of the maximum is 2. (3 b) A function that takes two parameters: an int array, an int n that is the size of the array, and an int pointer max that is to assign the maximum value in the array. The function will find and return the index of the last occurrence of the maximum value in the array and assign the maximum value to the pointer max. For example, in the array {1, 2, 6, 5, 6, 4, 3, 6, 4} the index of the last occurrence of the maximum value 6 is 7. in c

The code snippet :

Code snippet for two functions:

Calling the two functions in main:

-----------------------------------------------------------------------------------------------------------------------------------------------------------

Code:

#include <stdio.h>

int first_function(int array[], int n,int *max_value_first) { // the first function
   int index=0;
   *max_value_first = array[0]; // initializing the values
   int i;
   for(i=1;i<n;i++)
   {
       if (array[i] > (*max_value_first)) // checking if the current elemnent is greater than the previous max
       {
           *max_value_first =array[i]; //updating the index and max value
           index=i;
       }
   }
   return index;
}

int second_function(int array[], int n,int *max_value_second) { // the second function
   int index=0;
   *max_value_second = array[0]; // initializing the values
   int i;
   for(i=1;i<n;i++)
   {
       if (array[i] >= (*max_value_second)) // checking if the current elemnent is greater than equal to the previous max
       {
           *max_value_second =array[i]; //updating the index and max value
           index=i;
       }
   }
   return index;
}

int main() {
  
   int n; // size of the array
   printf("enter the size of array");
   printf("\n");
   scanf("%d",&n);                   // taking the input from user
   int array[n]; // initializing a n size array
   printf("enter the elements of array");
   printf("\n");
   int i;
   for ( i=0 ;i <n ; i++)
   {
       scanf("%d",&array[i]); // taking the input from user and storing it into the array
         
   }
   printf("\n");
  
   int max_value_first;
   int index_of_first;
   index_of_first=first_function(array,n,&max_value_first); // calling the first function
   printf("The max value for first_function is %d \n",max_value_first);   
   printf("The first occurence of max value is at index %d \n",index_of_first); // printing the outputs   
  
   
   int max_value_second;
   int index_of_last;
   index_of_last=second_function(array,n,&max_value_second); // calling the second function
   printf("The max value for second_function is %d \n",max_value_second);
   printf("The last occurence of max value is at index %d \n",index_of_last); // printing the outputs
  
   return 0;
}

Output :
