I want to convert the integer into a string.
int x = 693;
char chararr[max];
In my homework, x is unknown. but don't worry, I wont ask for the full code. I just need the part where you change the int into a string/array of char.
I'm thinking in circles from where to start?
Complete the function myitohex so that its converts 8-byte integer to string based hexadecimals.
Ex: printf("0x%s",myitohex(64,hex)); should printout "0x40" on the screen
char *myitohex(uint8_t i, char *result){
???
return result;
}
I wrote:
#include <stdio.h>
#include <stdint.h>
char *myitohex(uint8_t i, char *result){
*result = i + '0';
[Code] ....
0xp gets printed out which is wrong. I think *result = i + '0'; is wrong. What changes should i do on this row ?
I wrote the following code to solve this problem:
Read, from the keyboard, an integer greater than or equal to 1 (store it in a variable of type int).
Convert the integer to its representation in string format isolate each digit of the integer, convert it to the corresponding character (char).
Present the resulting string on the screen.
#include <iostream>
#include <ctime>
#include <cstring>
#include <ctype.h>
#include <cmath>
using namespace std;
unsigned GetNumberOfDigits (unsigned i) {
return i > 0 ? (int) log10((int) i) + 1 : 1;
[Code] ....
Why is it answering like this?
INTEGER ? 1999
STRING : œ
My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int base;
[Code] ....
Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...
Code:
{
int power;
int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";

I'm trying to convert a string into a integer and when I call stoi(line) it causes the program to crash.
int main() {
vector<int> numbers;
int i;
string line;
ifstream myfile ("example.dat");
[Code] ....
The file being read from looks like:
3
12
23
34
12 34
12 12
34 23
23 23
struct time
{ int t;
int h,m,s;
};
int main() {
time t;
int totalsecond;
char A[10],B[10];
[Code] ....
It gives error at line no 12.
For Example, it the entered string is: 0324152397 I want it to get stored in an array like-[0] [3] ...[7]. Secondly the string entered may be of any length that is defined only at run time. So, I also need to calculate string length. How could I do that.

how to do this?
im starting it now but going in the direction of using arrays
Just wanted to share a program I made. It was the answer to one of the end chapter exercises in the C programming book I'm using, asking the reader to create a program that adds all the digits of an integer.
Code:
/* Program to calculate the sum of the digits in an integer */
#include <stdio.h>
int main () {
int number, right_digit, sum = 0;
[code]....
I want to write a function which take an integer and return the number of digits in it i.e
int i = 123456
func(i) {
some code
}
output
the number of the digits are 6
I have an integer that the user enters. I need each digit of the integer to be set as an element of an array. the integer could also be entered as an array, but I need the user not to have to enter each element and press ENTER.

We never got into any gui stuff. It was strictly console apps. That being said I have been able to create a few small apps. I would like to start to create GUI based apps but I am kind of overwhelmed at the choices. I dont know where to go from here. Since I have c++ experience I would think Visual C++ would be the choice but i have been reading a lot of forums and getting other info.
Is there another language I should look at the would allow me to convert my program quicker or easier?
The console program I already created is very very simple and want to make a gui for.
Quick break down.

Only thing I want to add would be the ability to run the file from a remote site within the company LAN(not a priority though). Currently it needs to be run locally on the server.
Code:

int digit = number % 10;

I have a char *pch that points to an integer digit 1 or 2 or ... 9. To get the character that's 1 less, instead of converting to int, minus 1, then converting back to char, I tried (*pch -1) and that seemed to work. I suppose that's because the particular character encoding on my system is such that the digits are encoded in the same order and spacing as the integers they represent. So the question is does this "convenience" feature hold true for all character encoding systems?
View 10 Replies View RelatedOk so I'm in a programming 1 class working with c++. I have the following assignment:
Write a C++ program that:
asks for and accepts the Percentage earned with as a double (i.e. 75.45)
rounds it to an integer (>= .5 rounds up, <.5 rounds down.)
prints the original Percentage and the corresponding Grade and Points exactly as shown below.
prints an error message for any input that is less than 0 or greater than 100.
For example, if user enters 89.4, the program prints out:
Percentage: 89.4% Grade: B Points: 3.00
You must use an if-else statement to do this in your program.
Use fixed and precision output manipulators (see Ch. 3) to display the values with the exact precision shown above.
IMPORTANT:
Each if statement condition should contain only one comparison! read this again
This means code that is similar to this is NOT okay: if (Percentage >= 80.00 && Percentage <90.00)
This code is not acceptable because the if statement condition above has two comparisons.
(Hint: If you order your if-else chain statements correctly, you will only need one comparison in each.)
I have the program working, but I'm pretty sure I'm not rounding how my professor would like it to. This is my code:
#include <iostream>
#include <cmath>
#include <iomanip>

So my issue here is the rounding, and then theres the converting the double percetnage to an integer. In my next assignment I have to write the program with a switch statement.
I'm able to convert an integer to a vector<unsigned char> and back. However, when I try to use a nearly identical function designed for the long long data type, the last byte or two is broken.
Program code:
long long num = 9223372036854775551LL;
cout << "Before: " << num << endl;
vector<unsigned char> data = getBytes(num);
num = getLongLong(data);
cout << "After: " << num << endl;
Code for converting between vector<unsigned char> and long long:
Code:
vector<unsigned char> getBytes(long long value) {
int bytes = sizeof(value);
vector<unsigned char> data(bytes);
for (int i = 0; i < bytes; i++)
data.at(i) = (unsigned char)( value >> ((bytes-i)*8) );
[Code] ....
Output:
Code:
Before: 9223372036854775807
After: 9223372036854775552
Is there something special about long long that would prevent this from working? This problem doesn't happen with int.

I am working on an assignment about converting an integer number to its 2's complement presentation. The binary representation is consisting of a single linked list.
As we all know, the steps of this converting is to taking the reminder of the absolute value, then flipping the 1 to be 0, and the 0 to be 1 in the binary number. And the last step will be to add 1 to the binary number invers.
I wrote a code that implements every thin correctly. However, when I reached the part of adding 1, the program was hanged.
int Absolute; //the first step is to convert the number to the binry reprezentation
Absolute = abs (value);// by take the Absolute value of the negative number, then find the
while (Absolute !=0) //the binary reprezentation {
int res;
res= (Absolute % 2);

In formatting strings, how would I only get the decimals?
So, 1.456 would be .456(no digit before the decimal). I have seen a lot on removing the decimals or rounding to a certain place.
How can I read a file that contains numbers only, but read it by three digits at a time? I have a long string of numbers and every three digits corresponds to a particular number in itself. i.e. a string of 064045154 would need to be read as '064' '045' and '154'. I need to then subtract one from each of these numbers and the new values I need to convert into their ASCII characters and place these in a new file. This is what I have (focusing on the 'Decrypt' function) but all it does is in the new file place a string of the same character repeated over and over a total number of times equal to the number of integers in the numbers file.
Code:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
#include "limits.h"

View 3 Replies View RelatedI Need to write a function using C wherein I should do the following:
(i) The function will receive a string in a character pointer
(ii) This string will adhere to the following structure:
"Kentucky+New York+Arizona+Nevada"
The number of states can differ from 4 to 50
The delimiter between States can differ from '+' to ',', hence I would like to pass the delimiter to the function.
(iii) This string should then be sorted alphabetically from left to right.
The above example would then become: "Arizona+Kentucky+Nevada+New York"
(iv) This string needs to be returned from the function using a character pointer.
