C++ :: Take User Input As String And Test To See If Matches A Word
Dec 4, 2014
I'm creating a program that takes user input in the form of a string and tests to see if it matches a word. Each correct word will increase their score by one. Here is a portion of the code that is not working.
...
else if(s == 32) {
if(!currentLetter.empty()) {
currentLetter.erase(currentLetter.length() - 2, currentLetter.length() - 1);
} if(currentLetter.compare(oWord) == 0) {
[Code] .....
To me, this looks like it should do a very simple task as intended-take a String, compare it to another, and reset the word if they match or output incorrect if not. But, I'm not sure if there is some quirk in C++ with Strings, because this code always outputs Incorrect. Please try again. and the score never increases. I also tested this by literally setting the strings equal in the code, which still resulted in it not doing what it's supposed to.

I've been agonizing over this all day. The assignment is to capitalize every other word in a user input string.
My logic is as follows:
1. I have the program get each character until it encounters white space (using for loop)
2. Then it should capitalize each character after the white space until it encounters another white space (using while loop).
My problem though is when i try to create a condition for while loop i have to terminate is when white space is encountered, but the very first character to start the while loop is a white space..
I was told to define boolean values, but after trying a few boolean conditions I'm still stuck..
Code:
#include <iostream>
#include <string>
#include <cctype>
using namespace std;

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.

I'm working my way through some C exercises to get some practice and have hit a wall. I need to use a function to take a number, such as 1, and print out One.Here's what I've got so far:
Code:
#include <stdio.h>
int name(int n);
char numberOne[] = "One";
int main(void)
{
int n;
}
[code]...
However, when I run the code and enter "1" the only thing that gets printed to the screen is "(lldb)". I've tried changing it to doing it without variables and just printing "One" but that gave the exact same result.

Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int number;
int count = 0;
int numOfGuess = 0;
[Code] ...
This is words.txt:
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck
barber#a person who cuts hair
toast#sliced bread browned on both sides by exposure to radiant heat
radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects
red#of a color at the end of the spectrum next to orange and opposite violet

I need to write a C 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:
#include <stdio.h>
int main()
{
int i = 0;
char c, lower_c;
printf("Enter text
");
[code]....
I have started this code by making the letters lowercase.I am not sure how proceed after this step, the step of making the first letter uppercase.

Basically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.
I'm having trouble receiving that random word and I'm getting the definitions from the file.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;
[Code] ....
This is what is in the words.txt file
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck

I'm learning programming, and C++. I've got a question, but I couldn't solve my problem so far. I need to use arrays and only basic stuff to solve this:
Create a program that reads a word from the user and then print (cout) this word on contrary. It's simple, I know, but I can't do it,. I've tried some stuff but I don't get how I will get the proper values to do this. All I know is that I can use variable.lenght().

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 have a problem that states: age is an int variable and name is a string.
What are the values of age and name after the following input statements execute.
cin << age;
getline(cin, name);
if the input is:
a. 23 Lance Grant
b. 23 Lance Grant
Ok I have been fooling around with this book all day. My instructer wants us to build the program instead of just saying
a = 23 Lance Grant
How to input B. I mean when I write the program I do not know how to ask for two lines for one input.

I have been reading up on arrays and string array. I created a string string text[0] and it is defined by user input. I am trying to sort the input. I want Michael to read Macehil.
When I wasn't using an array and just a string I did this:
return sort(text.begin(), text.end()); a
And it worked fine. Do I need to change my string into a char? If so, would I static cast that?

I am writing a code in a class that will change the user input which is integer to a string. For example if the user enter 13347..the output should change to "one three three four seven" on the user screen.I'm not getting the right output.
Code below:
#include <iostream>
#include <string>
using namespace std;
string arr[]={"one","two","three","four","five","six","seven","eight","nine"};
class convertTo{
public:
int signed num;
int convet(){

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>

How would you search in a vector array from a user input string?
ex: user input : "Hello"
output: search vector array and find the line that has the string "Hello" and output the array "Hello" is on?

I'm trying to write a short program that takes the input from a user and trims any leading/trailing white space, and then checks how many words are in the string. Problem is, I'm only allowed to use stdio.h and stdlib.h. How can I accomplish this? Also, how would I check if any of the characters which were entered aren't either a number, letter, or '-'?

I want to create a game that will test the attention and mind flexibility of the user. So the challenge is The user will be given 50 rounds, and each round should generate a random combination of text and words.Then the user must Press 'Y' if the UPPER CASE text spells out a color that match the BACKGROUND. But if the text are in LOWERCASE the user must press 'N'.(Note: you can change the keys to any key from the keyboard if you wish to)
Then I also want my program to record the high score each time the program prompts the user if he/she wishes to play again.
I also want to control the combinations by NOT allowing the text color and background color to be the same.
I also want the combination to generate an AVERAGE of 50% correct combination and 50% wrong combinations. The I want to use is only Red, Blue and Green
HIGH SCORE Determinants:
1. Accuracy ( (Number of corrects / 50 ) * 100% ) - The higher the better.
2. Time in seconds (Time Ended - Time Started) - the lower the better.
Computation for high score: 10 000 * ( (Accuracy) - (2 x total Attempts - Time) )

Modify your code by adding your own tests to see if your functions work right. Include at least 6 separate tests, of your choosing.
For example, test the compare function with the first parameter as a blank string -- then with the 2nd as a blank -- then both. Test compare with the first string shorter than the second -- then the other way around. Test your copy function with long strings.
I am struggling with how to use the compare function with a parameter as a blank string. I tried leaving the first parameter blank but doing ("",text) but I don't think that is the correct way of doing this.
#include <cstring>
#include <iostream>
using std::cin;
using std::cout;
using std::endl;
int myStrLen(const char[]); // return length of null-terminated string stored in char array
