this is my code:

#include <iostream>
#define MAXAMP 9
using namespace std;
int main()
{
int n,Amp,Fre,elem,k,l=0,m=0;
while(cin>>n)
while(n--)
{
cin>>Amp>>Fre;
if(Amp>MAXAMP||Amp<=0)
break;
//if(l=0 ...

Read the input from stdin, not a file.
#include <iostream>
#include <stdio.h>
#define R 100
#define L 100
using namespace std;
int main()
{
char rot[L][R];
int n=0;
for(int i=0;i<100;i++)
for(int j=0;j<100;j++)
rot [j]='\0';
while(gets(rot[n]))
if(n<100)
n++;
for(int i=0;i<100;i++)
{
for(int j=0;j ...
