I'm creating a program that should create a structure of a list of people entered by the user; the only problem I'm having is with the %c. When I have it, the loop only occurs once; if I put a %s, the loop occurs up to 25 times, but it doesn't write to the text file. Here is the code:
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>

I want to create three files whose names are same but extensions are different. I have to take the name from user. I tried following code but it didn't worked ...
Code:
printf("Name of the file:"); scanf("%s",name);
printf("Format of Input file:");
scanf("%s",ext);
f1=fopen(name.ext,"r");
f2=fopen(name.dat,"w");
f3=fopen(name.src,"w");
f4=fopen(name.RMH,"w");
why this is looping in an error message. I am inputting the entire file name when I run the program and it just keeps falling into my "if(!inputfile)" statement. Let me know if there is anything I'm just not seeing.
#include "File.h"
#include <iostream>
#include <fstream>

How to open a file that the user input
ifstream InFile;
ofstream OutFile;
InFile.open("???.txt")
I'm trying to develop a programme which, amongst other things, prompts the user to enter the filename which is to be opened. This is what my code looks like currently:
char filename[20];
FILE *myfile;
printf("Enter the full file name you would like to open:");
scanf("%s", filename);
[Code] .....
However, this only ever returns File Not Found - the file is stored in the same directory as the program, and I have tried looking up this issue online, to no avail ....
This program will allow the user to input string then scans the file if it contains the same string given by the user. But i always get "MATCHED" even if i enter random string. I tried and tried to place the if statement in different positions but i dont get my expected output.
Code:
#include<stdio.h>#include<stdlib.h>
#include<time.h>
#include<string.h>
int main() {
int found;

So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;
int progfiles() {

This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer
i
c
i
Press any key to continue . . .
The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output
"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"
A program which takes input from user and write it to a file then it reads data from that file then it should search for specific data such as email adresses or url etc.

How to get this thing to work. All i need to do is ask user to input a name and then it brings out the line from the .txt file containing the information.
For example in my case I'm doing a member search function I'm required to ask user to input the name of the customer and then print out all the details (which consumes 1 text line in the .txt file)
Here is the code, This is the write to text file method (100% working)
Code:
cout << "Customer Name: ";
cin >> name;
// ...
ofstream myfile("customer.txt", ios::app);

Following is the program I wrote it basically takes 9 inputs and then save them into binary file. then print out the data stored in binary data and find inverse of it then print the inverse out. but its stuck in a loop somewhere.

int a[3][3],i,j;
float determinant=0;
int x;
FILE *fp = fopen ("file.bin", "wb");

Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;
and define two namespace globalTypes (tys and fys) for the function :
class_level deriveClassLevel(int num_of_credits) ;
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy.
and the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.
….
}
I did this in parts so I got it working with a four year criteria without the user defined name spaces.
include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
[Code] ....
So that worked fine then I tried with name spaces -
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;

I am making program that allows the user to determine how big the array size will be and then asks the user to make up numbers to fill the array. Every time run the program on Dev C++ it says "program has stopped working"
Heres My Code:
//Assignment 19 Program 2
#include <iostream>
using namespace std;
int main()
[Code].....
In this simple end-of-chapter problem, the ages of two people are to be compared and determine who's older. The problem I'm experiencing is that the second user name input is being skipped and going straight to the second users age.
So while running the program it looks something like:
What is user ones name?
<input name>
How old are they?
<input age>
What is user twos name?
How old are they?
<input age>
<if statement result>
Here's my code:
Code: #include <iostream>
#include <string>
using namespace std;
int user_one_age;
int user_two_age;
string user_one_name;
string user_two_name;
[code].....
So I've got this form that a user puts in a numeric value into a text box. This value then has to be placed into a byte string of data so that it can be transmitted over as a packet. Bellow is what I have so far:
Code:
Byte[] OUTBuffer = new byte[65];//Allocate output memory buffer
Byte[] INBuffer = new byte[65]; //Allocate input memory buffer
if (setmSpeed == true)
{
OUTBuffer[0] = 0; //Not used, must be set to 0
OUTBuffer[1] = 0x85; //Command mode
[Code] ....
I've put in red the area where I'm having issues. I've tried different methods and have not been able to get this working yet. It only works if I speciffy the value manually as with OUTBuffer[1] = 0x85;, but I want byte 2 of OUTBuffer[] to be set with what I put in the text box.
So im working with forks and creating 2 fork processes. One child and parent. What im trying to get the child to ask me for a value. Then the parent would start to figure out the value and keep trying. Once it figures it out its tells them you got it and simply stops the program. I cant seem to get the program to keep guessing and stop when the number is found which sends a sigint. Here's what i have so far.

#include <stdio.h>
#include <unistd.h>
#include <signal.h>
#include <stdbool.h>
int main() {
int j, i,pid;

I have this code here that counts the number of alphabetic letters the user's input,the number of characters total, the number of words and the number of "the" that was used. However now I need to alter the user's input to have two spaces after the end of each period, no spaces between a word or comma and each sentence has to have a capitalized letter and display them at the end. And I'm stuck on the altering part. I briefly started the 2 spaces after each period but it won't display anything.

I have written a program and i had to pass an array into a function and now i have a variable for the subscript of the array and i was the user to input data, specificlly a string, more specifically first and last name without having to create two arrays, i have to do this with other things in the program as well, here is part of the program:
int addFunc(const int totNum, string city[],string state[],string street[],string name[],
int addNum[],int zip[],int telNum[],double bal[],int dateLp[], int addCount, int accNum, int usNum)//function will add a new account {
int countAf = 1;
if (usNum < 20)

since around 2hours im really fighting with the cin command.It doesn't matter what exactly im trying, it's just not waiting for user input and keeps directly using 0 as "entered" value.
int Value;
cout << "Enter a new value: " << endl;
cin >> Value;
cout << "The value has been set to: " << Value;
I'm trying to make a simple program that accepts user input, simple stuff. When the user (me) enters a number to be sent to the console and i press enter so it accepts the data, it closes the command prompt and thus ending the program. I just need to find a key that i can use to continue but doesn't close cmd.

I am a beginner in C++. The program I want to create is as follows. The program will take a sentence as input from the user in italics and display it.
The output will be:

How to take user input in italics.
Create a program that will ask the users name, age, and reddit username. have it tell them the information back, in the format: your name is (blank), you are (blank) years old, and your username is (blank).
So I started making my program
#include <stdio.h>
int main(int argc, char* argv[]) {
char name;
int age;
char username;
printf("Please input your name,your age,and reddit username");
scanf(" %c %d %c", &name, &age, &username);
printf(" %c %d %c", name, age, username);
return 0;
}
My program outputted H 0 and an upside down question mark. I was thinking that maybe the error in the program was that i was supposed to use %s instead of %c but im not entirely too sure.
