I noticed something that when I tried printing factorial of number whose value was out of bounds of the data type ; It displayed zeros continously when i gave the print command ! For instance , factorial of 100 ;
Why doesn’t the compiler rather shows an Error that the data you are trying to store is excceeding the limit ??

When the number goes out of bounds, for eg, let the range of integers be -1000 to 1000, inclusive. If you store 1001, then it will take value -1000. If you store 1002, it takes value -999. This is what actually happens.
You might be getting 100! as 0. This is because, while computing 100!, number went out of bounds and took the value 0 (precisely, 34! is saved as 0). Now any number multiplied by 0 is 0. So all factorials>=34 will give 0 as answer, and you might be wondering the reason why.
