EG:
#include<stdio.h>
int main()
{
int Q1=2,Q,N,a[20];
scanf("%d",&N);
while(1)
{
int j=0,sum=1;
Q=Q1;
while(Q>0)
{
a[j++]=Q%10;
Q=Q/10;
}
for(int i=0;i<j;i++) // 15
{
sum=sum*a[i];
}
if(sum==N)
{
printf("%d\n",Q1);
break;
}
Q1++;
}
}
BUT:
\a.c||In function 'main':|
\a.c|15|error: 'for' loop initial declarations are only allowed in C99 mode|
