How to produce a password field with asterisk ****** .....
I feel as if I'm so close and I'm just messing up a value somewhere, but I am at a loss as to what I should change. Here is my code:
#include "stdafx.h"
#include <iomanip>
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[]) {
[Code] ....
The assignment is to plot the functions, by implementing a function having the following prototype:
void plotPoint(double y);
This function should print a single "*" symbol, in a position determined by the value of y, and then a newline. The position of the * symbol can span over 80 columns: each column should represent a delta of length 0.1 in the value of y, and the zero should be placed on the 40-th column.
For example:
• placePoint(0) should print the * symbol on the 40th column
• placePoint(0.1) should print the * symbol on the 41st column
• placePoint(1) should print the * symbol on the 50th column
• placePoint(-1) should print the * symbol on the 30th column
Here is what I have so far:
#include <iostream>
#include <cmath>
int a;
int b;
int x;
int y;
int Func1(double a, double b )/>
[Code] ....
I'm lost now as to where to go to plot. I know that depending on the option chosen I call the corresponding function to return a value for y which is just then plugged into a function to plot it on columns of y.
The requirement is to capture statistics of uuid occurrences for ALIVE/SEARCH/BYEBYE (it can be all 3, combinations of 2 each, or one alone) in a dynamically populated file in run time.
I am able to print all 3 combinations, but not in combination of 1 or 2 e.g.
If my input.txt is like this :
uuid:22314754-a597-490b-8a93-02cfae01036b ALIVE 16
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:50e65653-7525-485d-83bf-d293558c4264 SEARCH 132
[Code]...
Code:
#include<stdio.h>
#include<string.h>
struct uid
{
char uid_val[100];
char state[100];
int temp_count;
int alive_count;
int search_count;
[Code]...
Gives the following output ->output.txt)
Device ID ALIVE BYEBYE SEARCH
uuid:22314754-a597-490b-8a93-02cfae01036b 16 8 8
uuid:50e65653-7525-485d-83bf-d293558c4264 32 8 132

uuid:T0100203354 1 2 3
I want to generalize the code such that uuid occurrence does not have to be all 3 (ALIVE/SEARCH/BYEBYE), the occurrences can be any combination and code should work. e.g my code gives wrong results when input.txt contains the following:
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8

uuid:55076f6e-6b79-4d65-6497-180373763bc1 SEARCH 111
uuid:T0100203354 BYEBYE 2
I am using ubuntu for gcc/g+ compiler.
I have been skimming and searching but dont know how to word the search just right to find what I need to know. I have written simple stuff with the support of tutorials like weight conversion or loops counting up to a set number. Nothing amazing. The other day I found out how to input and print a string rather than a single text character which i though was bad ass. I even got it to read multiple strings on a single line and found a way to read multiple lines. I can even format it to read both integers and characters on the same line as long as I know the predefined format.
On to my question... How do I read multiple lines with both carecters and integers. for instance:
nissan 1996
toyota 1998
or more comples like
nissan gtr 1996
toyota markii 1998
I want to use
int year;
char make[10]; maybe need to use char make[10][10]; for an array i would guess.
char model[10]; optional for the extra data
but reproduce what i read in a different order. say...
1996 nissan
1998 toyota
vice the original format.
this is what I have tried.
Code: scanf("%s %s", &make,&year);
//The way I seen to read multiple lines was on here
scanf("%[^/t]", %make);
But this wont let me separate the two into two differnet definded data types. Let alone use printf to display them in reverse order.
I am working on a program where a user first enters a key of 26 characters, they then choose the number of lines they'd like to use with a max length of 40. Once they have entered the key and chosen the number of lines, they then enter text into the chosen number of lines, before that text is ultimately encrypted. I have it working as far as accepting the user's 26-character key, accepting their choice for number of lines, but when the user is typing in their lines of text, it only allows 6 lines before it moves to where the text would be encrypted.
View 3 Replies View RelatedI have a certain method of encrypting text. You get the first character of the word. For example in the word "hacker", you get 'h', and then you get the last character 'r'. The encrypted word until now is "hr". Then we get the same word with the 'h' and 'r' removed, now it's "acke". I do the same thing and get the first character 'a' and the last one 'e' and them to the encrypted word: it is now "hrae".
The left letters of the word are "ck", again we do the same thing and take the first character 'c' and the last character 'k' and and add them to the new encrypted word so it is "hraeck". The above word has an even number of characters and at the end had 2 characters left 'c' and 'k',first and last, in some cases of words with an odd number of characters, only one character is left! I'm completely lost on how to encrypt and decrypt this.
I have a simple decryption program but I cant get it to encrypt/decrypt text read from the keyboard using getline (), did i declare wrong?
#include <iostream>
#include <string>
using namespace std;
char text[ ]
(here I have my void decrypt/encrypt functions)
int main () {
cout <<''Enter text to encrypt''<<endl;
getline(cin,text);
I want to encrypt Mac address to 4 digit number which can be decrypted to original MAC address.
View 9 Replies View RelatedI encounter this from a library:
( *(reg8 *)(pinPC) |= CY_PINS_PC_DATAOUT)
From my understand the cast (reg8 *) applies to the result of the bitwise OR. But what is the left most asterisk doing?Is it just dereferencing the casted pointer?
i have to make a programs that prompts the user to enter quiz grades and add them up. For examples the user enters 6 test grades they are out of 5 so he enters 0-5 and i store them in the array. This part works great but now i have to print out a bar of vertical asterisks for every part too. So if at the end we have one test grades that are 2 grades of 1 points, 1 grade of two point, 2 grades of three point and 1 grade of 5 point it will have to display them as this
There are 2 grades of 1
There are 1 grades of 2
There are 2 grades of 3
There are 1 grades of 5
i need to do for loops but i am stuck on what to count too and what to print i know i will need cout << "*" and a couple of spaces.
#include <iostream>
using namespace std;
int main (){
int size;
int tests;
int a[6]={0};
cout << "How many quiz scores will you enter: ";
cin >> size;
[code]....
i have my basic C program here (i'm new to C language):
Code:
#include <stdio.h>
int main()
{
int grade;
int A=0;
int B=0;
int C=0;
int D=0;
int E=0;
[Code]....
As you can see, it's only for counting how many students got the grades from A to E, but the problem is that i need to change it from numbers into asterisk
for example: 4 students got the grade A, and 3 students got the grade B
instead of displaying
A=4
B=3
i want it to display
A=****
B=***
Getting close but I think I am stuck on the second loop. The input you put in will be doubled (and it's not supposed to).
Code:
int main() {
int n, i, j, k;
printf("What would you like the height to be? (Positive odd integer)
");
scanf("%d", &n);
[Code] .....
I have to place two asterisk triangles on top of each other BUT only using 3 for statements. I have gotten the first one:
for(int a=1;a<=10;a++) {
for(int b=1;b<=a;b++)
cout << "*";
cout << endl;
}
I need the output to look like this:
*
**
***
****
*****
******
*******
********
*********
**********
*
**
***
****
*****
******
*******
********
*********
**********
The only kicker is I can have a total of 3 nested for loop statements.
So, I'm going to write a recursive function for a asterisk pattern but I'm stuck figuring out how to create a stopping case for it, better yet, I'm unable to describe the pattern completely.
*
**
-*
****
--*
--**
---*
********
-----*
-----**
------*
-----****
-------*
-------**
--------*
( - represent white spaces )
What I've been thinking:
* Every odd row has 1 * with 1 incremented white space
* Every "pair" of asterisks equals 8 total (EX. 8 one pair *'s, 4 two pair *'s, 2 four pair *'s)
Unfortunately, that's all I got. how I can represent this as I function. Once I figure out what my stopping case should be, I think I can do the coding on my own.
When i try to compile this code it gives me a error during run-time saying "*program name* has stopped working"
Code:
#include <iostream>
#include <memory>
using std::cout;
using std::endl;
using std::unique_ptr;
[Code] .....
Why is this happening? Also why do you need the asterisk on smart pointers to assign them a value? Is it just because, or is there a reason.
This program needs to display a vertical graph of asterisks showing production for each plant in the company ...
Here is what I have so far:

display a vertical graph showing
productivity for each plant.

I'm a novice with C programming and i have to solve an error in the following code. The code works like you enter a password called "uoc" and it shows as OK. But surprisely when you entered another password as "Cambridge" it works fine too.

if (fp == NULL)

puts(password); When I read the string password, it outputs -> abcd123"
I don't know where it takes the (") because the password on the file is abcd123...
