Go4Expert - View Single Post - random subset made by random selection of different elements from a given set

elshadai

Hey all,

My name is Elshadai,

I am just a beginner in C/C++. I want to write a code in C/C++ the can select randomly a subset of integers both different from a given set. To be more concrete I have the following situation:

A=[1,2,3,4,5,6,7,8,9,10],

I want to make a subset of 4 elements from A whose element are chosen from A randomly and those element must be different from each other. I need a sets like :

B=[1,7,4,9] or C=[2,10,7,1] or D=[10,3,5,6] ....

Is there any one can help me?

Thank you so much
