I saw here that we can there is a data type "long long int". Can we use it on 32 bit machines?
And as we use %d for int in scanf(),printf() functions, what to use for long long int?
And also what is the range of long int on a 32 bit machine?
Thank you.
long long int is 64 bits.
long int is long, thus usually 32 bits.
%lld should be fine for printf, but you should really look up the format specifications instead of asking. It's easy.
And yes, you can use long long on 32-bit machines.
I am new to this thread, where to look for format specifications?
And plz, the range of long int?? Can it hold numbers as big as 4 x 10^9?
If long is 32 bits (it's not guaranteed to be), then it can hold up to 2^32 - 1, or half that if signed.
Same goes for 64 bits: 2^64 - 1, or half if signed.
Specifications? Use google!
Hi,
I am new this topic as well as to the forum. Can any one pls give me a sample program for AIX 32 bit machine
1. assign 999999999999 value to appropreate data type
2. print the above value.
Welcome, Vinu_pl. :)
Try an unsigned long long int. If your compiler doesn't support long long, then try unsigned long int, and see if it works.
Don't be afraid to try these things, Vinu. You have to be willing to explore to get to know programming. Get into it! :)
999999999999 would need 40 bits. So the next data type that would be big enough is a 64-bit integer.
