C++ :: Program That Basically Validates User Input With Text File
May 12, 2014
I'm having the upmost hardest time doing this program that basically validates the user's input with a text file. The text file is like so and below that is the work I have so far...
"user1"
"pass1"
"user2"
"pass2"
etc!

I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)

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;
[Code] ....
I know I have some stuff to mess around with but I am currently stuck with two errors, first -
Error1error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartupC:UsersstephenDocumentsVisual Studio 2013ProjectsinputConsoleApplication1MSVCRTD.lib(crtexe.obj)ConsoleApplication1
then -
Error2error LNK1120: 1 unresolved externalsC:UsersstephenDocumentsVisual Studio 2013ProjectsinputDebugConsoleApplication1.exeConsoleApplication1

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;

I am writing a spell checker for a exercise for a class I am taking online. I have to load a huge text file of 143092 words into a hash table.
The program segfaults on word number 63197. Is there a way to debug this in gdb without having to step threw the function 63197 times.

I need to write a program that reads four float numbers from the input.txt file, then it prints out the greatest of the four numbers into the output.txt file. I did everything, but the numbers don't print out.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile;
ofstream outFile;
float number1, number2, number3, number4;

I'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
// Password Log
#include <iostream.h>
#include <fstream.h>
#include <string>
#include <time.h>
using namespace std;
ofstream login;
[Code] ....
What my problem is when I choose "Input new login info" it automatically inputs I have no clue, and calls next program.

It seems to be going null. I can't get a null value, I want it to accept input till the user hits enter with no text typed. I've tried checking to see if the input is NULL, "", and " " all to no avail.
Code:
#include <stdio.h>
#include <sys/shm.h>
#include <sys/stat.h>
#include <iostream>
#include <fstream>
#include <string.h>
#include <cstring>

string info = "";

I need the program to do a calculation after the user inputs 10 numbers . This is what I have tried so far:
int count;
float value, high,low, sum,average;
sum=0;
count=0;
input:
printf("Enter a number (enter negative value to finish program):
");
scanf_s("%f",&value);
[Code] ....
output:
average=sum/count;
if(count==10) {
printf("total values :%d
",count);
printf("The Highest value :%f
Lowest Value: %f
",high,low);
printf("The average of the values is:%f
",average);
}

I built a program that accepts two input from the user, using a array inside a loop, it is pass to a function inside a class which will display the two number, the problem is when the user is inputting a number and it is 1 the program continuously as the user to input a number, and when 2 is entered the program ask another number and end, but for example you entered 2 and 3. . . it will then outpu 2 and 4 (so 3 + 1 ) and always the last number is plus one. here is the code.
main.cpp
#include <iostream>
#include "newclass.h"
using namespace std;

So we have a weekend assignment that is "Write a c++ program that will allow a user to input their first name into a string, and use the switch/case statement to produce the following output. Your Program should prompt the use rwith the numbers and the options for each (school, classification, and mood) allowing them to make a choice"
My issue is with the output. The output at the end is the number that they input and not the name of the case they chose, so if they chose option 1 for school it does not print out "BRCC" at the end for the output it prints a 1.
#include <iostream>
#include <string>
using namespace std;
int main(void) {
string name;
cout << "Please enter your name: ";
cin >> name;

I need a program to run that will accept an input for user id. It will take the customer input and capitalize the letters, and return invalid id with the user inputted values. Then if it's valid it will add a counter counting the number of letters and numbers. It will keep track until the user puts in !. It seems when I try to pass values from the array to my toUpper function to capitalize it it doesn't seem to work right.

I am so close to finishing this program of games, but I'm running into some issues while debugging it.
I've attached the google drive folder since there are several files (ignore the ones with [conflict], etc)...
First, I have the main menu using a switch to select the game. The default was set to exit. If initially when immediately opening the program you put in for say, a letter, it would exit like its supposed to. But if you went and played any of the games ], went back to the main screen, and entered a letter then, it would crash. I've put in a testing line to make sure that you enter a number, and not anything else.
Now however, if you play a game and then want to go back to the main menu, it will simply skip over waiting for your response and close the program. The same thing happens in the slot machine, I want to have it spin the slot machine by pressing enter, but it simply skips over the input, and I'm not sure why.

I need to create a command where the user inputs a character and it'll exit out the program rather than executing any of the other code.
For example :
If I wanted to do like
char key;
if (key == D || key == d)
{
}
What would I need to put in between those brackets under the if statement to allow the user to enter the letter D and it would close out the program?

I'm trying to write a program that capitalizes every other word of a user output. (ex: if input is "i love you", the output is "i LoVe YoU").
I am using a for loop (although an if loop might be easier?) and I'm assuming that it is possible to write this program using a for loop (although I may be wrong--maybe only if loops can write this program). I have everything down EXCEPT the last step where I have to print the entire sequence. What i have so far is:
Code:
#include <cs50.h>
#include <stdio.h>
#include <string.h>
{
// get user input
printf("Type a sentence: ");
string s = GetString();
[Code] .....
The code above basically only prints out the capital letter (ex: input is "hello", output is "EL"). I don't know how to print out the entire sequence.

// clang++ -g -std=c++11 main.cpp -pthread
#include <iostream>
#include <thread>
#include <unistd.h>
void thread1(void) {
while(1)
[code]....
Thread 1 does some background work, and thread2 is waiting for the user's input. If I join thread1 then the app can never exit. If I neither join nor detach thread1 then I get "terminate called without an active exception Aborted" which is not a good thing to have. If I do detach on thread1 does thread1 ever terminate? If not, how to terminate it? Also, how do I check if it's terminated or not?

It's a tic-tac-toe program. I haven't finished doing everything I need to for the project, I'm just trying to get certain parts working as I go.
Anyway, my problem: The program will print the board and ask the first player which square they want to mark. Then it will print the updated board, print the question for the second player to input their square choice but not actually stop to let the user enter anything. Instead it prints the board again and then prints the question for player one again -- this time stopping to let them type in their choice.
Here's my code:
#include <stdio.h>
// Function prototypes
void printBoard(char board[3][3]);
int main() {
int quit = 0;
// Loop so game continues until player quits
[Code] .....
And it looks like this when I run it, as an example:
-------------
| 1 | 2 | 3 |
-------------
| 4 | 5 | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'C' enter a square: 5
-------------
| 1 | 2 | 3 |
-------------
| 4 | C | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'U' enter a square:
-------------
| 1 | 2 | 3 |
-------------
| 4 | C | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'C' enter a square:

Also, how do I check if it's terminated or not? -- I realize it's platform specific, I am on Linux.

My program works primarily by receiving user input however; using 'char' and 'fgets' i have to stipulate how many characters i want assigned, and this isn't practical for what I am after. Example below.
Code:
char example[50];
printf("What colour is the sky?
");
fgets(example, 50, stdin); Is it possible that the assigned number (in this case '50') is determined strictly by the user input?
for example, user input is Blue then 50 is then 5?
