I know I've posted this code a couple of times now so I feel really stupid asking again for help but the requirements for the challenge that I'm working on changed a little bit on me.

What I now need to do is take in a list of numbers, assuming it will be an even numbered list of numbers, and compute the cycle length of the pairs of numbers given. But when I accept the numbers at the command line, the program crashes. I know it's because of my inexperience with pointers and arrays of pointers.

Here is the link to the challenge that I'm working on.

Code:

/*
program overflows @ command line
*/
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int *inci; //holds the incremental value of i
int *origi; //hold the original value of i to increment
int *num1, *num2; //numbers to be compared
int count = 0; //count is the more permanent storage for counting cycle length
int temp = 0; //temp is the temporary storage for testing greatest cycle length
while(argc > 1)
{
int i = 1;
*origi = atoi(argv[i]);
*inci = atoi(argv[i]);
*num1 = atoi(argv[i]);
*num2 = atoi(argv[i+1]);
while(*num1 <= *num2)
{
while(*num1 != 1)
{
if(*num1 % 2)//if i is odd
{
*num1 = (3 * (*num1))+1;
++temp;
}
else // assumes that i is even
{
*num1 = (*num1)/2;
++temp;
}
if(temp > count) //stores the largest temp number into count to be printed later
{
count = temp;
temp = 0;
}
}
*num1 = ++(*inci);
argc -= 2;
argv += 2;
}
printf("%d %d %d \n", *origi, *num2, count);
}
return 0;
}
