written in C
my task was to make a script that reads [m;n]
and then does
m,m+1,m+2,...,m+n;
and prints only the numbers that have a residue equal to 3 or 6 after diving the m`s by 7


#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main ()
{
int array[100],array3[100];
int n,i,y,m;
y=1;
printf("Type m\t");
    scanf("%d",&m);
printf("Type n\t");
    scanf("%d",&n);
for (i=0;i<=n;i++)
 {
    array[i]=m+i;
 }
for (i=0;i<=n;i++)
    {
        if(3==array[i]%7)
        {
            array[i]=array3[y];
            y++;
            }
            else
            if (6==array[i]%7)
            {
            array[i]=array3[y];
            y++;
            }
        }
 for (y=1;y<=n;y++)      
 printf("%d\n",array3[y]);

    return 0;
}

so /prog/ doesn't know how to fix this?
