Using IDA,
```
int __cdecl main(int argc, const char **argv, const char **envp)
{
int result; // eax
int v4; // [rsp+8h] [rbp-8h]
int v5; // [rsp+Ch] [rbp-4h]

v5 = 1048576;
puts("enter an INT");
__isoc99_scanf("%d", &v4;;
if ( v4 <= 0 )
{
puts("no enter a positive number only");
result = -2;
}
else if ( v4 + v5 <= 152 )
{
print_flag();
result = 2;
}
else
{
puts("sorry!! Try again");
result = -1;
}
return result;
}
```
