I really appreciate the help you guys have been giving me, but I just have one more quick question. I have to Write a C program that uses at least an additional function called by main to calculate and print the sum and difference of corresponding elements of two integer arrays with 5 elements each.

So far I have:

code:

---

 #include <stdio.h>
void printArray (const int a[][5]);
void main (void)
{
int array1[][5]={15, 13, 80, 5, 16};
int array2[][5]={10, 9, 100, 6, 15};
int Sum_Array, Diff_Array;
printf ("Values in array1 are:\n");
printArray(array1);
printf ("Values in array2 are:\n");
printArray(array2);
}
void printArray (const int a[][5])
{
   int i;
   int j;
for (i=0; i<=1; i++){
 for (j=0; j<=2; j++){
   printf ("%d ", a[i][j]);
}
printf ("\n");
}
}
 

---

In my first array, I keep getting -4195236, and a couple of other weird, large negative numbers. I have no idea why, I follwed the example that was given in class. Any suggestions?

Large, strange numbers are generally indicative of dangerous, random memory access. In this case, you've got two two-dimensional arrays of one row each--I think you want one array with two rows and 5 columns, or two one-dimensional arrays.

If you're going to be taking any more programming classes, I suggest learning how to use gdb--it's very, very helpful.

I'm assuming that you're in Eziefe's 140 class? If so, you can meet me in the Java lab tomorrow morning at around 11:30 and I'll give you a hand. I should have a large pair of headphones on. Just ask people if they're "jake".
