say we have,
int a[]=int a[5];

how do we fill 5 elements i.e 1,2,3,4,5 randomly in a[i](where i=0..4). using for loop.
example
a[0]=4
a[1]=2;
a[2]=3;
a[3]=5
a[4]=1

I was practicing arrays. I came up with this thought but i couldn't figure it out. I can fill random number using for loop, but random number generates duplicate number.I was trying to figure out without duplicate number..
Thank you

You could fill the array with numbers 1...5. Then generate two random numbers 0...4 and exchange the elements at those random positions. This could be done several times.
