Getting random array input.

Language C,

say I have

string array[]={"some", "some1", "some2"};
int x=0
array[]=random(0-3);

so then, if it was say, 1, array[1] would be displayed, being some1.

(not sure if the declaration of array[] is correct, unsure of random() and unsure of array=random() )

Also, I created a structure and I want to know if this is a legal assignment

genInv.axe=axe[rand(0-3)];

(first post show random() and this on shows rand(), I am not sure which to use so I put both :P). So basicly, 0-3 picks from 4 different positions in the array and assigns that value to genInv.axe.

You can generate a random number in the range of 0-3 by following

int randomNumber;

/* this will generate a random number from 0 to system defined RAND_MAX */
randomNumber = rand();

/* This will limit the random number value from 0-3 */
randomNumber = randomNumber%4;

Now you can use this number as Index to your array.

outputName = array[randomNumber];
