C++ :: Command Prompt Will Not Disappear After Input Names?
Nov 12, 2014Here is a code snippet which is a bit annoying.
Code:
cout << "Put in the names of people, press q to exit" << '
';
while((cin >> people_inp) && (people_inp != "q")){
Person *p = newPerson(people_inp);
[Code] ....
The problem of this code is when you put in the names(via cin) and press enter command prompt will disappear. What should I do so that Command prompt will not disappear after I input some names? I mean it disappears without you pressing a key.
C++ :: Write A Program That Will Read Names From Input File
Apr 24, 2014I have a lab with the following instructions:
Manually create an input text file called Lab22BInput.txt with the following data:
Dove
Doe
Alston
Zebra
Egg
Write a program that will read the names from the input file. Print out each of the names read to the screen. The program should go through the list of names and determine which comes 1st in the alphabet. The program should determine how many letters are in this name. Print out the name that comes first in the alphabet and the length of the name.
I have created the input file, and the data correctly outputs to the screen when I run the program. However, I do not know what kind of logic to use to sort them alphabetically and determine the amounts of characters.
So far I have the following:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
string str1, str2, str3, str4, str5;

Write a program that allows the user to input a name and the program should then read the file and search the matching names among the boys and the girls. If the name is found it should output the name and the names rank. It should also indicate if their is no match. How to start this.

C++ :: Longest String Does'n Print On Same Line
Aug 4, 2014I try to learn string class, resolving some problem, but i have some dificulties.The is ok, but when i print the longest string it does'n print on the same line.I enter the number of string, after that i enter the first string until i introduced from keyboard "#" character. I enter the second string and so on.Look at these example :
For i = 3;
Text[0] : I learn class String#
Text[1] : I dont learn class String#
Text[2] : String#
It print me like that : Text[1] :
I dont learn class String More than that look at the next example :
For i = 3;
Text[0] : I learn class String#abcdef
Text[1] : I dont learn class String#
Text[2] : String#
You see that in the first sentence i have continue to introduce some characters after # character and look what is happened :

C/C++ :: How To Print New Line Without Carriage Return
Jul 28, 2014I am using C++ to write data into a (.ini)file. However, when I try to print the value '0A' I am getting '0D 0A'. (this is what I see when I copy the output to HexEdit). From what I can figure out, '0A' is the ascii for 'new line' so write function automatically adds the '0D' which is 'carriage return'. What I want is to print 0A alone. how can I do this?
Note: Windows it is working fine, but linux it is not working...

C++ :: How To Enter And Print X And Y Coordinates On One Line Separated By Comma
Nov 22, 2014I'm trying to enter an 'x' and 'y' coordinate on only one line separated by a comma. But I keep getting a syntax error. Here are the lines of code I'm using. This has to be simple. What am I doing wrong with this code?
Code:
cout<< "Please enter the x and the y coordinates of the first point,"<<endl;
cout<< "use a comma to separate them. " <<endl<<endl;
cin>> "You entered: " >>x1>>",">> y1 >>"for the first point" >>endl;
C :: Print Listing With Line Numbers - Cannot Execute / Run Program
Feb 18, 2013The problem is with the first "Type and Run," where the code looks like this:
Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>
void do_heading(char *filename);
int line = 0, page = 0;
[Code] ....
I am using the gcc compiler in Ubuntu 12.04 LTS and I get the following error:
Code:
print_it.c: In function "main":
print_it.c:36:15: error: "stdprn" undeclared (first use in this function)
print_it.c:36:15: note: each undeclared identifier is reported only once for each function it appears in
print_it.c: In function "do_heading":
print_it.c:49:16: error: "stdprn" undeclared (first use in this function)
I was told that "stdprn" can be recognised by a DOS based compiler and the book says I can try using "stdout" instead. It looks like this now:
Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>
void do_heading(char *filename);
int line = 0, page = 0;
[Code] .....
It compiled OK with the gcc compiler but I only get this when I run the program:
Code:
Proper Usage is:
print_it filename.ext
I am not sure whether I should continue looking into this but even when I tried compiling and running it on Windows, the .exe file won't even launch. The other ones do but this first one doesn't.
Questions:
1. What should be done to make this program run?
2. Even though the book says "don't care" if the reader does not understand the items (It's Day 1/Lesson 1), I would still like it to run as I don't want to experience compiling and running problems in the future. Should I even bother doing this section of the book or is it obsolete and should be skipped?

Nov 26, 2013I want the phrase "BUY TICKET" to trigger something, i'm thinking an if statement, and then assign the number after the phrase to another variable. There will also be other commands entered from the input file such as "BUY RAFFLE' "TOTAL REVENUE" on the following lines. Sounds like I need to compare a string(?) to a constant phrase, and if they match have it run the specific code?
Code:
//scan in from file
fscanf(ifp, "%c", &input);
if (input == 'BUY TICKET'){
//Run this
}

C :: Pointers Array De-allocation And Input In A Line
May 24, 2013I have three questions concerning the below code I have written, which is expected to do basically as the attached diagram illustrates:
Code:
#include <stdio.h>
#include <stdlib.h>
double getAverageGrade(int studentGrades[] , int size);
int* getStudentInfo(int * numCourses);
int main()
[Code] ...
(1) How may I display the averages to 2 decimal places, namely why doesn't %.2lf work? The program gives 89.00 for 89 and 90, for instance.
(2) How may I read the number of courses and the relevant grades in a row for each student?
(3) How may I free (de-allocate) my array of pointers, namely grades? Does it suffice to use free(grades)?
C :: Use Fgets And Sscanf To Read A Line Of Input
May 21, 2014I'm new to C/C++. I am attemping to use fgets and sscanf to read a line of input, and confirm it is a positive number.My code works great, except for the case of a negative number. When I enter a negative number, my while loop seems to run infinitely, with stdin providng the same input over and over again.
