I have a program that will convert a string of numbers into a barcode that consists of :'s and |'s. But the only issue I have is that the numbers are all being output backwards.
#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;
string codes[] = {
"||:::", ":::||", "::|:|", "::||:", ":|::|",
":|:|:", ":||::", "|:::|", "|::|:", "|:|::" };
[Code] ....
How to make it so an output for a program would print out the string in reverse/backwards? I was just curious on how to do this.
View 6 Replies View RelatedLets say I have my name "Kevin".
What would the program be so it reads "niveK"?
How to write the program for that?
write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];
cout << "Enter what you would like to be UPPERCASE: ";

So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4
The code should store each line in a list as such...
4, 3, 2 ,1
Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4
Here is my code...
struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}
I want to process data (using fstream) and print out the progress. This doesn't work with cout <<, only with puts, but this causes a line-break but I want a progress bar like this : [=====================].
I've already searched for an hour in the reference and with google and I dont manage to put a string without a linebreak:
while (ein.good()) // loop while extraction from file is possible
{
c = ein.get(); // get character from file
if (ein.good()){
[Code]....
how to do it without the linebreaks..
I am writing a small editor for RSL coding, and ive got an external program "3Delight" to compile the code.
Now i want the output from that exe to be captured in a string once the compilation is comlete, but all of the methods ive found online dont seem to work for me. Ive tried using _popen which works if i run a normal command like "dir", but not with the exe.
This is the function ive been using that works with the normal commands
std::string exec(const char* cmd) {
FILE* pipe = _popen(cmd, "r");
if (!pipe) return "ERROR";
char buffer[128];
std::string result = "";
[Code] .....
and this is how i was calling it, but it just returned an empty string, even though the exe printed "Compilation successful"
exec("""%DELIGHT%/bin/shaderdl" "E:/RenderManShaders/TestArea/Source/basicDiffuse.sl"")
I've been trying to create an output string in my application using OutputDebugString, cout, printf but to no avail.
Here is my environment:
OS: Windows 7
VC++ Version : 2008 Express Edition
I keep getting this error after I input:
Code:
Unhandled exception at 0x54AE350B (msvcp110d.dll) in Random.exe: 0xC0000005: Access violation writing location 0x0131CA21.
Code:
#include <iostream>
#include <cstring>
//Prototypes
void lastChar(char *);
int main() {
const int LENGTH = 21;
[Code] ....
It builds without any errors. I am just trying to output the last character in the C-string. Am I doing this all wrong?
Code:
Prompt the user to input a string,
and then output the sum of all the digits in the string.
Sample Run 1:
Input -> A111B222C
output -> 9
Sample Run 2:
Input -> ABC123XYZ32100000005555555555zzzzzz

I have been trying to get this my class template to print out a string for me, however I am getting :
" error C679 ' No operator found which takes a right hand operand of type std:: string' "
I have tried various way to get this going however I cant get past this error. I understand that templates functions how ever i am not sure why i am not getting my string to be displayed.

I'm reading in a string from the command line into a char array followed by a series of ints which are read into an int array.
The command line
Code: lab3 word word word 0 0 2 3 results in the following output:
Code: Word: .N=▒
Number of Words: 0
Word: .N=▒word word word
Number of Words: 3
Num: 0
Num: 0
Num: 2
Num: 3
Here is the source code:
int main(int argc, char *argv[]){
if(argc < 2){
//command line must have at least three arguments (one
//char, one integer)
printf("Error: invalid number of arguments
[Code] .....
Where is the .N=▒ coming from?
So basically here I have a menu in my C program and if I were to select option 2, I would enter a string up to 30 characters and it would output each block of 16 bytes should be shown which contains a character in the requested string. However, when I compile and run the program and search for the string, nothing happens. what I may be doing wrong?
Code:
else if (select == 2){
printf("Enter a string of up to 30 characters: ");
scanf("%s", &userstr);
//Compares both user's string and file string
for (i = 0; i < size; i++){
if (strcmp (buffer, userstr) !=0){

Write one program that receive a string, tokenize it by ' ' delimiter and show the output, using STL
So, I write:
#include <stack>
#include <iostream>
#include <vector>
#include <string>
using std::stack;
using std::cout;
[Code] .....
And...
Type any string and I'll say its proprieties:
> A B C
String length: 5
Words number: 3
Word 1: (split(input)[0])
A
Word 2: (split(input)[1])
B C
Word 3: (split(input)[2])
C

What am I doing wrong?
I am writing a code in a class that will change the user input which is integer to a string. For example if the user enter 13347..the output should change to "one three three four seven" on the user screen.I'm not getting the right output.
Code below:
#include <iostream>
#include <string>
using namespace std;
string arr[]={"one","two","three","four","five","six","seven","eight","nine"};
class convertTo{
public:
int signed num;
int convet(){
cout<<"Enter a number to convert to string "; cin>>num;

I'm trying to get this programme to work but I can't get it to output the string data at the end of the line.I have copied and pasted the line in question below but it may be a prob with the prog further down.
It reads character input ok but doesn't put one string into another or recognize when a string is quoted in a printf.

printf("%s what is your second name?
", surname, name2, name);
#include <stdio.h>
int main ()

I want to separate this binary string every 4 characters..I am trying to get a better understanding of how variables are stored in memory and I am looking at their binary address for a pattern..I see a pattern for the last 4 bits

I've been typed out a C program to let the user define the size of their string , and key in characters for this string , the program would then prompt the user for a character to search for in the string and return it's index value. Eg. Index of c in abc is 2. My code is as shown:
#include<stdio.h>
#define SIZE 20
int search(char x[SIZE+1] , int n , char s);
int main(void){
char x[SIZE+1] , s;
int n , index;
[Code] ....
However , after I key in my characters for the string , the program does not prompt me to input a character to look for, it just prints it out and returns some funny number. But the program works just fine is I move this portion to the top :
printf("Enter alphabet to find: ");
scanf("%c",&s);
what I'm trying to do is output a certain string depending on the color I see in the video feed. For right now, what I've done is threshold the feed so that everything above a certain brightness shows up as Red. Now I want to have something that says if there's any red in the feed, then I output a "1" to a text box on my user interface that's showing the feed. If there is no red, then I output a "0" to the text box.

I'm working on a CGI application. I'm trying to test my input with a switch statement and output the result with html tags to populate a web page. From within the switch, I've coded as follows:
HTML Code:
switch(mFunc) {
case 0:
cout << "<p><b>YOU ENTERED THE FOLLOWING TO BE CALCULATED:</b></p>" "<h2>"<< number1 <<"+" << number2 << "</h2>" << endl;
break;
case 1:
cout << "You've entered" << number1 <<"-" << number2 << "to be evaluated" << endl;
break;
I know that I'll need to put this in an html body with a content type as such:
HTML Code:
cout << "Content-type: text/html
";
cout << "<html><body>
";
Am I able to do that directly inside of the switch statement?
If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.
What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?
String s("Hello");
String t("There");
1. s = s + t;
2. s += t;
Ok, so I'm writing this code and when I build it keeps saying cannot implicitely convert type int to string even though I declared my variables as string. Why is it giving me this error?

string result="";
string beep;
string spin;
