exploit buffer overflow vulnerabilities to damage objects, including ARG (actual parameter when the function is called), RETADDR (address of the next operation instruction in the memory), EBP (stack frame status value before the function is called), and LOCVAR (local variable in this function)....

•Worst Case: O(n)– If an element isn’t found in the list. Then the function will check all of the n elements. •Typical Case: O(n)– requires an n/2 check. Linear search is implemented using following approaches • Begin from the first element of array list and one by one...
You shouldn't use this code though, because the gets function doesn't care about the size of the input. If the input is bigger than (in this case) 100 characters, it'll overflow the array. That is called a "buffer overflow", it's a serious security vulnerability. Use ...
To test this, we compile the following code that we gave as an example in our article entitled “Connect Function in C language”. This code, although very simple, is very interesting because it connects us to the Google host through the HTTP service and allows us to send the commands and...
Functions are generally used when that particular operation needs to be called multiple times; It is beneficial to use Functions instead of writing a specific operation's code multiple times. Syntax: function function_name(argument1, argument2,..., argument n) { return value; } Two types of ...
