CHAR Array - stuffed with values - with more size than it holds
Hi All
I am simulating a problem in the production where i faced a situation.
Please find the following example program which i simulated.
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
{
char str1[20];
char str2[20];
double t1=0.0;
double output_value=888.00;
double count=0.0;
memset(str1,0x00,20);
memset(str2,0x00,20);
char output_str[20];
char output_str1[20];
memset(output_str,0x00,20);
memset(output_str1,0x00,20);
for(int i=0;i<50;i++) (Purposely specifying as 50 and not 20 as per the variable)
{
count=count+1.0;
sprintf(output_str, "%12.2f", count); (When str1 is exhausted i.e after 20th byte it is taking the value from str2 mentioned below)
strcat(str1,output_str);
strcat(str1, " ");
printf("The string length of str1=%d\n",strlen(str1));
if (i != 0)
output_value= 1 + output_value;
sprintf(output_str1, "%12.2f", output_value);
strcat(str2, output_str1);
strcat(str2, " ");
printf("The str1 has the value =%s\n\n",str1);
printf("The str2 has the value =%s\n\n",str2);
}
printf("\n\n\n The output line 3=%s\n",str1);
}
Please let me know if str1 is stuffed more than what it can hold, should it take the values from str2 ? as arrays are stored by contiguous memory location.

je::object::array
JE::Object::Array(3pm) User Contributed Perl Documentation JE::Object::Array(3pm)
NAME
JE::Object - JavaScript Array object class
SYNOPSIS
use JE;
use JE::Object::Array;
$j = new JE;
$js_array = new JE::Object::Array $j, 1, 2, 3;
$perl_arrayref = $js_array->value; # returns [1, 2, 3]
$js_array->[1]; # same as $js_array->value->[1]
"$js_array"; # returns "1,2,3"
DESCRIPTION
This module implements JavaScript Array objects.
The "@{}" (array ref) operator is overloaded and returns a tied array that you can use to modify the array object itself. The limitations
and caveats mentioned in "JE::Object/"USING AN OBJECT AS A HASH"" apply here, too.
METHODS
See JE::Types for descriptions of most of the methods. Only what is specific to JE::Object::Array is explained here.
$a = JE::Object::Array->new($global_obj, @elements)
$a = JE::Object::Array->new($global_obj, $length)
$a = JE::Object::Array->new($global_obj, @elements)
This creates a new Array object.
If the second argument is an unblessed array ref, the elements of that array become the elements of the new array object.
If there are two arguments and the second is a JE::Number, a new array is created with that number as the length.
Otherwise, all arguments starting from the second one become elements of the new array object.
$a->value
This returns a reference to an array. This is a copy of the Array object's internal array. If you want an array through which you can
modify the object, use @$a.
