C :: How To Read In A Character Followed By Integer Without Space

Feb 13, 2014

how to carry out the conversions. The assignment is the normal hex to octal and Quart (base 4) via bit munipulation which I have worked out myself. However, I have been trying all day to figure out how to read in a string such as H1234, or O4567. How to parse the input I can handle the remainder myself. I'm just stuck and I've tried for hours.

C :: Make Program Read Integer Until A Space?

May 23, 2013

I am trying to make my program read an integer until a space, namely ' ', is pressed, and then move on to the next command. However, all my attempts hitherto with both scanf() and getchar() have been to no avail. Every time it proceeds to the next command only upon pressing Enter, which is not quite what I want.

C :: Read From Stdin (File) Character By Character

Nov 10, 2013

I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below

rhhrkkj$hghjhdf$ddfkrjt

While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.

Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.

C++ :: How To Read TXT File Character By Character

Oct 6, 2013

In my program, I'm supposed to read a text file (the name of which is given to me as a command line paramater, as long with an integer), and display the text in a specific format (each line can only be as long as the integer). However, I'm having trouble even reading the text file. I don't know the syntax. I'm only allowed to edit the function that does the formatting, and the code in that is

void typeset (int maxWidth, istream& documentIn)

I don't know how to 'read' the file, as most examples online are ifstream, or openFile or something like that. What I want to do is just read the first character of the file, and continuously keep reading characters until the end of the file.

C++ :: Convert From Integer To Character String

Oct 2, 2013

I have been trying to write a function which can convert a number from an unsigned long integer to a readable ASCII character string. this is what I have come up with, but I am receiving some very strange characters in return. Could the problem be that I am telling a char to = an unsigned long int, (cString[i] = product[i])?

void convertToString(unsigned long con) {
unsigned long product[10];
char cString[10];
const unsigned long begConvert = 10 ^ 10;

C/C++ :: For Loop To Print Given Character Number Of Times Specified By Integer

Feb 11, 2014

The function uses a "for" loop to print the given character the number of times specified by the integer.

How can I make a for loop to do that?

So.. my code looks like this:

// cpp : Defines the entry point for the console application
//
#include "stdafx.h"
#include <iostream>
using namespace std;
void printMyInteger(int myInteger, char myChar) {

[Code] ....

So.. here is my error:

C++ :: Universal Order / Spacing Of Character Encoding For Integer Digits?

Feb 7, 2012

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?

Visual C++ :: Prompt User To Enter Integer Value And Character Code To Indicate Conversion

Sep 14, 2013

I'm expected to write a c program for this question :

Using these header files
#include <stdio.h>
#include <conio.h>

Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.

C++ :: Why Two Scanf Needed To Read Character

Mar 11, 2012

Below given is the code, which allocates memory for a structure dynamically and stores value in its member. The problem is in the last scanf statement which reads 'ch'. The code will be in infinite loop as it doesnt executes the last scanf statement. The solution for this is (i use this) to add one more similar scanf statement for 'ch' in the very next line. If i do so, it executes the statement, reads 'ch' and then continues.

I want to know why it behaves like that..

struct student{
int usn;
};
int main(){
char ch;
struct student *s;
s=(struct student *)malloc(sizeof(struct student));

C :: Using Scanf To Read A Character From Standard Input

Nov 1, 2013

So running the following code

int main(void) {
char c;
int i=1;
while (scanf("%c", &c)==1)
printf("loop sequence %i: %c(%i)

[Code] ......

Done it seems a "carriage return" serves two purposes here, one is to signal the program to read in the character typed in before the "carriage return", another serves as a second character typed, how can i do this cleanly, that is without having to use a "carriage return" as the second character to signal "I've typed in the first character already".

C++ :: Read (three Digit) Integer Representing Value To Be Encrypted

Nov 3, 2013

I have been working on some C++ code that doesn't seem to be going right. I'm wanting it to read a (three-digit) integer representing the value to be encrypted, a (one-digit) integer representing the encryption key, encrypt the value and print the encrypted value. The encrypting method used is that each digit in the given number is replaced by ((the sum of that digit plus key) modulo 10) then the first and last “encrypted” digits are swapped.

For example, if the number entered was 216 and the key given was 7, after applying the encryption procedure described the first digit (2) would become 9, the middle digit (1) would become 8 and the last digit (6) would become 3. The first and last encrypted digits are then swapped. The program displays the encrypted number: that is 389 in this case.

#include <iostream>
using namespace std;
int main() {
int isolateDigits();
int replaceDigits();
int swapDigit1withDigit3();
