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.

I am trying to write a program to get user's input but only accepts alphabetic characters, nothing else and I want it to ask the user to enter a valid word until they have finally entered a valid one. I have the following code for it but it does not work properly.
void CheckBound (char word1[], int SIZE1) {
int i;
int w1[SIZE4]= {0};
int found;
for (i=0;i<strlen(word1);i++) {

How do I have the user enter only letters?
#include <iostream>
#include <limits>
int getInt() {
int x = 0;
while(!(cin >> x))
[Code] ....
But this function prompts the user to only input integer values. I was thinking if I could maybe try tweaking with this one so that the user could only enter letters..no luck though. So how can I have the user input letters only?

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 ....

I'm having a problem with the two while statements in my UDF.
- 1. It will run both while loops twice...?
- 2. It now goes into a continuous loop.
- 3. When it did work, it would only return 1 value to the main()...?
#include <iostream> // for use of "cin" & "cout", endl...
#include <iomanip> // for formatting setw function
#include <cmath> // for the general math computations
#include <string> // for creating descriptive strings
#include <sstream> // used to convert a string to an integer
//user defined function
int userValue (int);

How can I create in my C++ program so a user can paste a text and then choose a character on specific line and place?. The above thing isn't that important. I just want to place a character on a specific line and place.
I mean something like this:
Enter a character:
You choosed " / "
On which line do want the character?
You choosed "Line 1 and 2"
Where do you want the the to appear on the line? (left or right)
You choose left.
Results:
Line 1. / hello
Line 2. / hello

Question simple like that: Let user enter some words from keyboard, one word per line until a '.' (period) entered then print out result, for example:
Code:
Enter a word: word1
Enter a word: word2
Enter a word: .
You have entered 2 word(s):
word1
word2
Problem is I don't know how to declare the array of character at the beginning since I don't know neither how many word user may enter nor how many letter of each word. So I go ahead and declared like this: char word[20][50] but I know it is not best way.
Code:
int main () {
char word[20][50]; //array has maximum 20 words, each word maximum 50 character
int i=0, number_of_word;
do {
printf ("Enter a word: ");
[Code] ....

I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {
[code]....
EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.

I'm trying to code a program to read the user's input and have it:
-count vowels
-stop counting vowels after '.' or '?' (ie. abcdjwef is 1 a, 1 e; while fje.fwdfeiii is just 1 e)
-closes when ENTER is pressed after a '.' or '?' is found (ie. closes after 'abacds. ENTER' as well as 'as.fefsdf ENTER')
-display the number of vowels
Is there any way to do this with only 'cin >> userInput' and a while loop checking for punctuation?

I want to be able to write a program where I can record user input but combine it with command line arguments. For example I do a simple getline(); and the user types test how to combine it so it could be like test /q and it gives a different output depending on what additional input was added. Can this be done with lots of different inputs?

I'm suppose to write a program using (for loop) that asks the user to enter any amount of numbers, so that it can display the smallest and largest. My program successfully finds the largest, but it is always displaying 0 for the smallest, I think Im doing something wrong with the internalization but I dont know what to change it to.
This is what I have ....
#include <iostream>
using namespace std;
int main() {
int amount;
int count;
int number = 0;
int smallest = 0;
int largest = 0;
cout << "Enter total numbers to process: ";

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.

Here is a simple drinks machine programm. It basically consists in the user selecting a drink that it's presented, if the user selects correctly the number representing a certain drink, the machine shows the user what was the drink he selected, after his choise the machine asks for money insertion, if the user inserts the incorrect amount of money, the machine shows an error saying that user need to insert the correct amount of money.
My problem is that, if the user selects a different number other than those presentend, the machine displays an error saying that he needs to choose a valid drink, but i can't find a way to reprompt the user again after the error has been displayed. here's the code.
// ***Drinkins Machine*** by Roxmate
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
// initializes the variables coca, fanta, iced and drink to be used in switch function,so that the user can choose what drink he wants.
int coca = 1;
