C :: Detecting Number Of Uppercase Letters?

Mar 20, 2014

Just wrote this extremely simple program but it seems to be malfunctioning. It counts correctly the number of uppercase letters in a string so long as i don't use the space-bar. once I add a space it only counts the number of uppercase letters of the first word..

printf("I ..........ing love programming");

Code:

#include <stdio.h>
main()
{
char text[200];
int i = 0;
int uppercase = 0;
printf("Enter text:");
scanf("%s", text);

C++ :: Number Of Characters / Operators / Uppercase Letters And Numerical Digits

May 5, 2014

I have to code a simple program who determining the number of Characters (A character could be any alphabets, digits, punctuation marks, or special , Operators ( Operators are those symbols that are used in mathematica expression, such as,'+', '*', '/', '-', and so on.), Uppercase letters (Uppercase characters are those from A..Z) and Numerical digits ( A digit is any of the Hindu-Arabic numerals from 0..9). Why the output is wrong!

#include <iostream>
#include <string>
#include <fstream>
#include <cstdlib>
#include <iomanip>
using namespace std ;
int main() {
char text;

[Code] .....

This is my input file This is a possible factorial function in a programming language called LISP

(defun factorial (n)
(if (< n 2)
1
(* n (factorial (1- n)))))

This is my output:

The number of characters = 113
The number of operators = 3
The number of numerical digits = 3
Uppercase letters = 5

I think that "characters" is wrong, but I do not know why !

C :: Converting A String Array Into Uppercase Letters From File

Apr 19, 2013

I am new to coding Here is the problem. Have a program prompt the user for a filename to open. Change every alphabetic character in the file to a capital letter. Numbers and special characters should not be changed. Print the output to the screen.

Here is my code so far but i am only returning the last line of text capitalized from the file. I am trying to get the program to display all of the three lines of text from the file capitalized. The program displays the file correctly before i try and convert everything toupper();

Code:

Code: #include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <ctype.h>
int main()
{
char line[81], filename[21];
int i;
FILE *inFile;

C/C++ :: Function That Generates A Random String Of Uppercase Letters

Apr 19, 2014

I need to write a C function that generates a random character array (i.e. string) of uppercase letters - getchar and putchar are the only IO functions that I can use. Below is what I have already - I am iterating for as many times as I am required to, and am modulating rand() by 25, (total letters in the alphabet). I'm trying to see how to get the random letter from the % 25, and also how to do this without toupper() [not sure if I can use that function].

void getRandomStr()){
char str[40];
for (int i = 0; i < 40; i++){
char c = rand() % 25);
str[i] = toupper(c);
}}

C :: Find Number Of Capital Letters And Punctuations In A String

Jan 28, 2015

write a C program which repeatedly reads in sentences from the user and reports on how many capital letters are in the sentence and how many punctuation characters. Your program will stop asking for input once the user has entered in a blank line. Consider the following example usage with the program. User input is marked in underline:

Enter a sentence: John and Mary went to Fred's house.
You used 3 capital letters and 2 punctuation characters.
Enter a sentence: I like A&W more than McDonald's.
You used 5 capital letters and 3 punctuation characters.
Enter a sentence:
Good bye!

Hint: make use of the standard C functions ispunct and isupper. Other requirements. You must make two functions.

Make a function called find_characters, which has a return type of void, and which has three parameters: one of type char * (a string to find characters in), one of type int * (a reference to int variable indicating how many capital letters are in the string) and the last one also of type int * (a reference to an int variable indicating how many punctuation characters are in the string). Your find_characters function should scan the string and update the two variables it has references to.Make a main function.

This function should repeatedly read in a string from the user, call your find_characters function, and output the information returned to it by the find_characters function indicating how many capital letters and how many punctuation characters were in the string. Your main function should stop reading in input when the user enters in a blank string (i.e., the user just hits enter without entering anything else in). You may assume that the user will not enter in a sentence longer than 100 characters

Code:
#include<stdio.h>
#include<stdlib.h>
#include<ctype.h>
#include<string.h>

int main(void) {

C++ :: Word Counter - Calculate Number Of Letters And Give Total Cost

Nov 4, 2013

I am currently working on an assignment.

#include <iostream>
using namespace std;

int main(int argc, char *argv[]) {
char letter;
int count = 0;
double ppl = 0;
double finalCost = ppl * (count - 1);

[Code] ....

I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:

You have 40 letters at $3.45 per letter, and your total is $138.00.

Everything compiles fine but when I run it the inputs don't work and it outputs:

You have -1 per letter, and your total cost is $-0.

C++ :: Detecting TR1 Support?

Feb 3, 2012

I have source code that is shared between two compilers, one supports TR1 and one doesn't. I've reverse engineered a few of the TR1 templates for the older compiler, but I need to be able to detect whether TR1 is supported or not, so as to include the correct header.

Something like this.

Code:
#ifdef SUPPORTS_TR1
#include <array>
#else
#include "mystl/array"
#endif
std::array<int, 10> myarray;

The compiler that supports TR1 is Visual Studio.

C# :: Detecting Previous Installs?

Jul 16, 2014

Say a user installs and uses the software for awhile. Then they uninstall it. Client wants the database containing client data to remain behind, in case they ever re-install the software. Which is fine.

So then.. they re-install the software. Client wants them to have the choice to either use the existing database, or to create a new one. When the software fires up, it always checks for the database, and creates one if it's not there. So how can I determine if the instance is a new install, or a current install, given that the database will be there no matter what?

C :: OpenCV And Detecting A Person With A Webcam

Jul 2, 2013

Code:
#include "opencv2/video/tracking.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc_c.h"

#include <stdio.h>
#include <stdlib.h>

[Code] ....

The above code is all I have so far. I got confused when I got to the part where my book on C tells me I need to use the cvCalcOpticalFlowFarneback() function to compare 2 consecutive images from the webcam and create the optical flow, and then measure movement between the frames to detect whether or not a person is moving through the room. How to do this, and the OpenCV wiki wasn't very descriptive on how to set it up for beginners. Honestly, the parameters just confused me and I didn't see a return value listed, or how you would get data from it.

C++ :: Overflow / Underflow Detecting Functions

Sep 15, 2014

I am performing arithmetic operations on very large integers that operate around the threshold of the maximum positive integer an int variable can handle (i.e. 2147483647) for a 32-bit machine. I have been studying the in-built functions in the C++ Standard Library for some time now where I came across some error detecting functions in the <cmath> and <cerrno> header files. The impression I got from the literature is that they are solely used in conjunction with functions contained in the <cmath> header file and not necessarily with fundamental arithmetic operations like addition and subtraction.

I need a means to know when my arithmetic operations generate overflows/underflows! Is there any way I can adapt the functionalities of these functions to my needs?

C# :: Detecting CD-ROM Drive And Grab Filepath Of Only CSV File

Jul 8, 2014

I would like the user to insert a CD into their computer and click on an button on my application that allows them to read the CD-ROM and find a specific file type, e.g. csv, and then grab the info in the csv file.

I already have my StreamReader setup grabbing a filepath.

Now I am just wondering...how do I detect the CD-ROM and how do I grab the filepath of the only CSV file on the CD-ROM?

What's behind detecting a CD-ROM and grabbing a specific file type from a CD-ROM?

I heard about DriveInfo

However, that only allows me to detect a drive but not look at it's contents.

Visual C++ :: GetTextExtent Not Detecting Font Size

Jun 3, 2013

I need use GetTextExtent and I don't understant why GetTextExtent always return the same value if I change some values of the selected font. This is my example:

Code:
LOGFONT lf;
pOldFont->GetLogFont(&lf);
CString sExampleSizeByChar;
sExampleSizeByChar = _T("hello");
DWORD dwPixelsByChar = dc.GetTextExtent(sExampleSizeByChar).cx / 1.15;

[Code] ....

Why I get always the value 24 when I call GetTextExtent if I change the font size?

C++ :: Detecting Application Startup And Exit Events?

Apr 20, 2012

I have written ( using VS2008 c++ ) a windows service which sends information about PC usage to a central database, as part of a PC availability setup. I have been asked to add the following functionality to it:

1) What applications are most used, when and how long for, and

2) What web sites are being accessed, again to find the most popular etc.

My main question is, what functionality is there to trap application start / close events from within my service ( just need the application name ), and secondly I am already using sockets to send information to a PHP script on a server, the best way to see what web pages are being accessed is to build in a packet sniffer, and extract the information from that.

C :: Lowercase / Uppercase Conversion

Oct 15, 2014

I am having trouble in creating a program (named "up.c") that should do the following:

- if you run the command ("up") with no arguments, it should read input from stdin and display it on stdout, converting lowercase letters to uppercase.

- if you run the command with one or more files (as arguments to the "up" command), your program should read input from each file and display it on stdout, again converting lowercase letters to uppercase.

I'm trying to create a single program that can do both of these, and handle errors gracefully. I've found that some codes work to convert the letters, but they seem overly simple and aren't giving me what I'm looking for in my program.
