Examples 14-A, 14-B and 14-C attempt to show how undetected (at compile-time) array-bound errors can cause problems --- compile and run them:

#include <stdio.h> #define UL 20 /* If necessary, increase the value of UL to that in error_fourteen_a.c, then compare what happens when you run the two programmes : */ main() { int a[10], j = 4000, i, k = 3000; printf("Value of j %d and k %d \n", j, k); for(i = 1; i <= UL; i++) a[i] = i*100; for (i = 1; i <= 10; i++) printf("%d \n",a[i]); printf("Value of j %d and k %d \n", j, k); }
