Josephous Problem

[daggerhunt]

Can anyone tell me what is wrong with my code?

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
typedef struct Josephous
{
    int pos;
    struct Josephous *next;
}node;
node *create(node*,int);
int Calculate(node*,int ,int);
int main()
{
    int n,m,res;
    node *head;
    printf("Enter no. of players = ");
    scanf("%d",&n);
    printf("Enter position to eliminate = ");
    scanf("%d",&m);
    head=(node*)malloc(sizeof(node));
    head->pos=1;
    head->next=head;
    head=create(head,n);
    res=calculate(head,n,m);
    printf("The winner is = %d",res);
    return 0;
}
node *create(node *head,int n)
{
    node *q,*temp;
    int i;
    q=head;
    for(i=2;i<=n;i++)
    {
        temp=(node*)malloc(sizeof(node));
        temp->pos=i;
        temp->next=q;
        q->next=temp;
        q=temp;
    }
    return head;
}
int calculate(node *head,int n,int m)
{

    node *q,*temp;
    int i;
    while(head->next!=head)
    { 
        q=head;
        temp=q;
        for(i=1;i<m;i++)
        {
            temp=q;
            q=q->next;
        }
        temp->next=q->next;
        head=temp->next;
        q->next=NULL;
        free(q);
        q=NULL;
    }
    return (head->pos);
}

gcc -std=c89 -pedantic -Wall -Werror 152488.c
152488.c:2:18: fatal error: conio.h: No such file or directory

Ok, so I commented line 2 out
gcc -std=c89 -pedantic -Wall -Werror 152488.c
152488.c:23:5: error: implicit declaration of function `calculate` [-Werror=implicit-function-declaration]
<line 23 is where you call the calculate() function>
<line 10 is where you declare a Calculation() function. I assume you meant calculation>

so I changed the initial uppercase letter in line 10 to lowercase
gcc -std=c89 -pedantic -Wall -Werror 152488.c
