一道用c语言判断素数的题

Question

#include
int main(void)
{
float x,y;
int n,m,j,i=1;
float c;
while(~scanf("%f%f",&x,&y))
{
n=x;
j=y-x+1;
int a[j];
int c[j];
while(n<=y)
{

j=1;
m=n*n+n+41;
if(i<=m)
{
a[j]=m;
c[j]=a[j]%i;
i++;
j++;
}
n=n+1;
}
if(c[j]!=0)
{
printf("OK");
}
else
{
printf("Sorry");
}

}   


return 0;

}

题目是对于表达式n^2+n+41，当n在（x,y）范围内取整数值时（包括x,y）(-39<=x 不知道我这样写改怎么去改，才不会WA报错
#include
代码更新
int main(void)
{
float x,y;
int n,m,j,i=1;
j=y-x+1;
int a[j];
int c[j];
while(~scanf("%f%f",&x,&y))
{
n=x;
while(n<=y)
{

j=1;
m=n*n+n+41;
if(i<=m)
{
a[j]=m;
c[j]=a[j]%i;
i++;
j++;
}
n=n+1;
}
if(c[j]!=0)
{
printf("OK");
}
else
{
printf("Sorry");
}

}   


return 0;

}

还是报错
