I'm using silverfrost 95 to coding fortran. I want to calculate large numbers for example 5^5432854
but it errors "integer overflow", I tried kind 8 but it errors "error 600 - The KIND number should be 1, 2, 3, 4, or 7" and also it's not working with kind 7.
What can I do?

I'm new to c++ so I don't know if there are any specific libraries that could do this. Any help would be appreciated!

Need to set a random number between say 3 and 7. Everything I find is for Swift 2 and no longer works in Swift 3.
Thanks
This should work for my purposes.
var tapsNeeded = arc4random_uniform(4) + 3;

I'm having a problem with my code, in which I try to generate a number between 0 and a dim user-defined variable. The line I'm having problem is:
arrayPos = rand()%dim;
I already called srand(time(NULL)) and the arrayPos is getting some wierd numbers like 9.267e-315 and so on.
Any ideas on how to fix it?
Thank you
The problem really was garbage memory, I restarted the computer and it worked like a charm

I've made some programs and saw that scanf and printf are considerably faster than using cin and cout? Most of my programs clear the execution time limit, mostly 3 seconds or 5 seconds, on online compilers when using scanf/printf which exceeded the limit while using cin/cout.

Generating random integer from a range
I am just starting to learn c++, and for a class assignment i'm supposed to use rand() and get a random number between 2 and 14. I know to get like between 1 and 10 i would do rand()%10+1
In my case would I need to do rand()%14+2?
I understand that others have posted similar questions, but they appear to all do between even multiples, such as 1 and 10, or 10 and 20 etc.
rand()%12+2
notice there is a gap of 12 number in between and your lower bound is 2.
