Question

a) Write a function that takes as input 2 parameters, an array and its size (both ints) and returns the max. Include the driving (main program also. To pass an array to a function, do the following: return_type my_function(int my_array[], int size)

b) Write a function that does the above but can contain duplicate numbers and is capable of removing them. Scan in input. Note you may need the sizeof( ) function which is one of the standard libraries.Thus you must #include < > this library.

PLEASE WRITE THIS FOR PELLES C PROGRAMMING! THANK YOU

Answer 1

#include <stdio.h>

// Function to return max

int my_function(int my_array[],int size){
int max = my_array[0];

// Loop through the whole array
for (int i = 0; i < size; i++){
if(max<my_array[i]){
max = my_array[i];
}
}
return max;
}

int main()
{
int a[5] = {1,4,6,7,2};
int x = my_function(a,5);
printf("%d",x);
return 0;
}

Output: 7

b)

#include <stdio.h>

int my_function(int my_array[],int n){
int count = 0,i,j;
//To store array elements after removing duplicates

int a[n];

// Loop through the array
for (i = 0; i < n; i++)
{
for (j = 0; j < count; j++)
{
if(my_array[i] == a[j]) // If duplicate break
break;
}
if (j == count) // Else add it
{
a[count] = my_array[i];
count++;
}
}
printf("Array obtained after removing duplicate elements:\n");

for (i = 0; i < count; i++)
printf("%d\n", a[i]);
  
int max = a[0];
int size = sizeof(a)/sizeof(a[0]);
for (int i = 0; i < size; i++){
if(max<my_array[i]){
max = my_array[i];
}
}
return max;
}

int main()
{
int a[5] = {1,4,2,7,2};
int x = my_function(a,5);
printf("Max element : %d",x);
return 0;
}
Output:

Array obtained after removing duplicate elements:
1
4
2
7
Max Element : 7
