Buffer-overflow

Buffer-overflow is a common computer security concern. Write a simple program, in C, C++, and Java, to declare a simple one dimensional array and then attempt to access an array element that is not within its bounds. For example, what happens if I declare an array to be in studentNums[10] and then attempt to access studentNums[11], studentNums[12], or …, studentNums[100] ?

Pseudo code

Rewrite the following pseudo code segment using loop structure Rewrite the following pseudo code segment using loop structure in the specified languages: K-> (j+13) /27 Loop: If k > 10 the goto out K <- k + 1 I <- 3 * k – 1 Goto loop Out: . . . a. Fortran 95 b. Ada c. C, C++, Java, or C# Assume all variables are integer type. Discuss which language, for this code, has the best writability, the best readability, and the best combination of the two.

Simple C Code

What are the values of sum1 and sum2? Let the function fun be defined as int fun(int *k) { *k += 4; return 3 * (*k) - 1; } Suppose fun is used in a program as follows void main() { int I = 10, j = 10, sum1, sum2; sum1 = (I / 2) + fun(&i); sum2 - fun(&j) + (j / 2); } What are the values of sum1 and sum2 a. if the operands in the expressions are evaluated left to right? b. If the operands in the expressions are evaluated right to left?

GUls

Why are the use of GUls and graphics beneficial in programming.

Java program:employee names, address and ph numbers and Cntrl + Z

I am looking for a java program that allows the user to create a file of employees, address, and phone numbers. Prompt the user to enter the filename, and then prompt the user to enter the employees names and their phone extension numbers. The user should press Control + Z after entering all of the data. The program then displays the data from the file just created. I would like to have the .java and .class files, please... :-)
