My professor at college stated that it is important to always initialize a function type because if you don't it creates a security vulnerability. He said that it is better to initialize it as zero and then let the programmer/user manipulate that value later on.Why is this a security vulnerability within the program?Here was the example:
BAD:
int x;
GOOD:
int x = 0;
I am trying to write a program that keeps track of social security numbers of customers I have to assume that its a four-digit number. When the program runs,it has to prompt that the user should enter a 4-digit number to record, or 0 to exit.
The program also needs to be able to give an error message if a certain number is entered more than once.
After all the numbers have been saved and you finally end it by pressing 0, it needs to be able to output all the entered SSN's.
Here is my code so far:
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
bool isExist(int ssn, int records[], int numberOfRecords);
[Code] ......
In this assignment, you are going to write a program that keeps track of the social security numbers (SSN) of customers of a bank. Please notice that we are going to assume that SSN is a four-digit number (e.g., 1234. 0123 is not allowed.). When the program runs, it prompts that the user should enter a 4-digit SSN number to record, or 0 (zero) to exit.
So far I have this:
#include <iostream>
using namespace std;
bool isExist(int ssn, int records[], int numberOfRecords);
int main(){
int ssn = 0;
int records[32];

I am having problems at the end of the program with the do-while loop to restart the program and the validation.

so my homework assignment is to make a program of which removes any notes in a program file.
for example, you run my program it will ask for a filename, when entered it opens the file, copies everything in it and removes any double forward slashes (//) and anything after that up to the new line character ( ) and anything between /* and */ including the /* and */.
i created the entire program and it removed the // and anything after that up to the new line character but will not remove anything after the first / when it finds a /*. This includes the */ at the end of the comment.
the section of code that removes the comments is
//this loop removes all notes
for(i=0;i<buf.st_size;i++) {
if((filecontent[i]=='/')&&(filecontent[i+1]=='/'))//removes notes using //
{
for(i=i;filecontent[i]!='
';i++)
filecontent[i]=' ';}
[Code]....
i know that the section that removes the multi line comments would not remove the final */ at the end if it did work, i was planning to fix that later once it removed the comment.

My program is ruuning perfectly only problem is that i must transform it to program uses class, class student . Am very beginer in using classes, so far i do very easy programs using classes.
so far i have this
#include "stdafx.h"
#include "student.h"
student::student(vector<STUDENT> studenti) {
vStudent=studenti;
[Code] ....
I try to make it but its too difficult for me. in that student.h and student .cpp is 50 errors..
Here is my code
#include "stdafx.h"
#include <string>
#include <vector>
#include <sstream>
#include <iostream>
#include <fstream>

I want to make a program which can run in another program. My program have structures flowing:

But check(keypressed) function only active in my program, It can't run in another program.
I've been working on a small SDL program and decided I wanted to throw the program on to a disc so I could show some people what I'm working on. However, when I try to run the executable, the program crashes and under more details it says that the fault lies on SDL2_ttf.dll .
Why does this program work inside of VS2012e and not in windows?
What I did :
Set the program to release, hit f6, and then tried to run the executable from windows.
Additional information :
Compiler : Visual Studio 2012 express
O/S : Windows 7 64bit
SDL lib : 32 bit version
For instance Code: int counter;
counter =0;
FILE *pfile;
pfile= fopen("g:myprog.txt" "w");
while (counter >100)
{ fprintf (case counter{something})}; how do I do this?
Cannot divide the real output of the AVERAGE.:
Code:
#include<stdio.h>
#include<conio.h>
struct student

char Name[50];

how to get the output of this program.. I'm not completely lost but I need it in the simplest terms.

is there anyway to have a program where it ask for three numbers and you shows which which number is the largest and which is the smallest, e.g.
Enter 1st number: 30
Enter 2nd number: 10
Enter 3rd number: 30
Largest = 30
Smallest = 10
I am working on a program to compute the natural log of numbers using several different methods, but I am having a couple of issues. Firstly, when using Borchardt's Algorithm I almost always end up with nan as a result, even though I am pretty sure I got the formula correct. Also, in my lnDemo.c file It doesnt give me the correct answer and the second time around I get a segmentation fault.
Code:
//myLog.h-------------------------------------------------------
//These functions will compute or aproximate the natural log of a number
//This method will use a formula to compute it
int lnFormula(double x, int m,double *result);

Can we use more than one 'if' subroutine in one program. I am trying to implement this but if I run the two subroutines at the same time the lower subroutine directly shows "invalid grade". But if I run one at a time then they work perfectly fine.
Why is this happening? Does the compiler think that its the same "if" routine. If so how do I segregate it???
Code:
printf("Enter a score:");
scanf("%d",&gr);
if(gr>=80 && gr<=100)
printf("A Grade
");
if (gr>=60 && gr<80)

I expected this program to print out:
Code: Enter your desired monthly salary: $2000___
Gee! $2000.00 a month is $24000.00 a year. Instead, it printed out:

Gee! $2000.00 a month is $24000.00 a year. I don't understand how it got the extra nextline in the middle.
