Question description

Can someone please help me to write a function in c

void printarray (int a[], int size); // print out the content of array a[] with size integers

int even(int a[], int size); // return the number of even numbers in array a[]

void insert(int a[], int size, int key, int k); // insert key into array a[] so key becomes the k-th element

void second(int a[], int size); // find the second largest number in a[] and swap it // with the first element in the array

void rearrange(int a[], int size); // rearrange array a[] so all the even numbers will // have indices less than those for the odd number

Thanks,

I did the whole thing  but is not working 


include <stdio.h>

void printarray (int a[],int size)

{

// print out the content of array a[] with size integers

int i;

for(i = 0; i < size; i++)

{

printf("%d",a[i]);

}

printf("\n");

}

int even (int a[],int size)

// return the number of even numbers in array a[]

{

int count=0;

int i;

for(i=0; i< size; i++)

{

if (a[i] % 2 == 0)

{

count++;

}

void insert(int a[], int size, int key, int k)

{

    int i;

    for(i=size-1;i>=k-1;i--)

        a[i+1]=a[i];

    a[k-1]=key;

}

void second(int a[], int size)

{

    int i,largest,secondLargest,index1,index2;

    for(i=0;i<size;i++)

    {

        if(i==0)

            largest=a[i];

        else if(i==1)

        {

            if(a[i]>largest)

            {

                index1=1;

                index2=0;

                secondLargest=largest;

                largest=a[i];

            }

            else

            {

                index2=i;

                index1=0;

                secondLargest=a[i];

            }

        }

        else

        {

            if(a[i]>largest)

            {

                index2=index1;

                secondLargest=largest;

                largest=a[i];

                index1=i;

            }

            else if(a[i]>secondLargest)

            {

                index2=i;

                secondLargest=a[i];

            }

        }

    }

    int temp=a[index2];

    a[index2]=a[0];

    a[0]=temp;

}

// find the second largest number in a[] and swap it

// with the first element in the array

void rearrange(int a[], int size)

{

    int i,last=size-1;

    for(i=0;i<last;i++)

    {

        if(a[i]%2==1)

        {

            while(a[last]%2!=0 &&last>=0)

            {

                last--;

            }

            if(last>=0 && last>i)

            {

                int temp=a[last];

                a[last]=a[i];

                a[i]=temp;

                last--;

            }

        }

    }

}

// rearrange array a[] so all the even numbers will

// have indices less than those for the odd number

int main(void) {

int a[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12};

printarray (a, 12);

printf("there are %2d even numbers.\n", even(a, 12));

insert(a, 12, 20, 3);

printarray (a, 12);

insert(a, 12, 0, 0);

printarray (a, 12);

insert(a, 12, 30, 11);

printarray (a, 12);

second(a, 12);

printf("calling second(): ...\n");

printarray (a, 12);

rearrange(a, 12);

printf("calling rearrange(): ...\n");

printarray (a, 12);

return 0;

}
