I need help with the program to display first 4 perfect numbers in the standard output and also funciton perfect(int,int*). Arguments of this function are natural number and the adress where you neeed to write the adders (of the perfect number I suppose). Function has to return 1 if the number is perfect, and 0 if it's not. This is what I've done so far. Help please.
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int perfect(int,int*);
int main()
{
int *arr,a;
int i,j;
perfect(a,arr);
}
int perfect(int n,int *arr)
{
int lim=8128,i,sum;
for(n=1;n<=lim;n++)
{
sum=0;
for(i=1;i<n;i++)
{
if(n%i==0)
{
sum=sum+i;
}
}
if(n==sum)
printf("%d ",n);
}
}
I think this code is helpful for you. The perfect function returns 1 when perfect otherwise return 0. The global array
divisor
which is used for collecting the addr. When theperfect
function returns 1 then I print the divisor array and initiate thedeivisor_count =0
. Please have a look:
