If you are a beginner, you will find it very unusual sometime regarding taking inputs. Some problems will say, "The Program will continue till the END OF FILE:, some will say "Stop taking input if N=0" etc etc. Some important ways to take input will be described here:
1. If you are said to take an integer number (n) as input till the End Of File/ (EOF):
int main(){
int n;
while(scanf("%d", &n)!=EOF){
...........
...........
}
return 0;
}
return 0;
}
