rand() generating segmentation fault
Why would this code produce segmentation fault :
/*
#include<iostream>
#include <stdlib.h>
#include <ctime>
using namespace std;
int main()
{
int i=0;
srand(time(0));
string location[]={"LA","delhi","Las Vegas"};
for (i=0;i<20;i++)
{
cout<<location[rand()%4]<<"\n";
}
}
*/
/*
#include<iostream>
#include <stdlib.h>
#include <ctime>
using namespace std;
int main()
{
int i=0;
srand(time(0));
string location[]={"LA","delhi","Las Vegas"};
for (i=0;i<20;i++)
{
cout<<location[rand()%4]<<"\n";
}
}
*/

I stand to be corrected here, but it looks like you've initialized an array with 3 elements and then are trying to access 20 elements of the array, memory locations that don't all exist, through the
for loop.
Nah, every loop iteration he's accessing from #0 to #3 element, but the #3 element doesn't exist.
Change from 4 to 3, near that rand.
