C++ :: How To Verify If A String Equals A Certain Word
Apr 3, 2013
I want to see if the value of a string equals a certain text. But I can't make it. There are two problems :
1) It seems 'tolower' doesn't work with strings. What to use then?
2) When I delete tolower, it works, but I have an output of "You didn't enter 'add'" even when I do enter 'add'. What's the problem? Is it due to the null byte? What to change?
Code: /* * Instruction_t - stores a specific instruction */ typedef struct { [code]....
I have a problem. When I run my program (which contains this), through gdb, I can see that burstTime does have a value ( such as 1, 3, 15, etc).But when I dequeue from my list, instruction->burstTime suddenly equals zero!
How to make a program to enter password and if password right I can change the curency. I only want to change from ringgit malaysia to us dollar.The program can convert currency many times.I only want to use stdio.h
#include <stdio.h> void main() { int pass; printf("Input your password"); scanf("%d",$pass); if (pass==4782)
[Code] ....
After this what should I put to complete this program?
I am working on a program where i prompt the user for his/her name and i have to verify that the name only contains alphabetic characters.
here is my coding. It works to an extent i just can't get it to work the way it is supposed to.
#include <iostream> #include <cstring> using namespace std; const int SIZE = 50; int main() { char name[SIZE]; cout << "What's your first name?" << endl;
[Code]...
when someone types in a name with only alphabetic characters it outputs valid name for how long the name is. For Ex: bob is three characters so it would output valid name three times. also when you put in a name with a number or character at the end it outputs valid name for the correct characters but also outputs the invalid character and invalid name which its supposed to do. the valid name should not be showing up though.
I want to make such application in which user make directed graphs along with relations between them. After that application show that which graph properties are proved in this graph e.g Reflexive, Irreflexive, Symmetric, Anti Symmetric, transitive etc
1. Create a variable named index and nitialize it to zero(0) 2. Prompt for and input a string value from thekeyboard. Store the string inthe string variable newstring[80]. 3. While (newstring[index] does not equal ‘ ’).
i. Display the character at newstring[index] followed by a NL ii. Increment index ====================================== ...
And this is what i have done so far and i dont know where I am wrong ...
Code: #include<stdio.h> int main() { int index = 0; //initialize index to zero since first elementin an array is numbered zero char newstring[80];
#include <iostream> #include <string> #include <iomanip> using namespace std; int main() { //Program Goal //Have 3 Strings to represent 3 categories //Have the user type in their name //Have the user type in a full sentence how they are feeling //Program should find the word in the user inputted sentence and display an appropriate response
I'm having trouble trying to turn a word into letters. I've seen other posts but they deal with a sentence and it only outputs the words only. What I want to know is how do they take a word (Ex: "word") and break it into individual letters, where I want to store them in a vector of string?
If it's not too much trouble, I would prefer without using pointers or "std:: " marks, since I am trying to avoid pointers and I'm using "using namespace std" all the time.
Ex:
In the example "word", it should output into:
"w" "o" "r" "d"
and I will push them back into a vector of string where each vector element contains a letter.
I have a difficulty with string methods for some reason. I tried solving a question from my book, which requires me to capitalize the first letter of every word in a string. I kept trying for maybe two hours yesterday, re-reading the string chapter to see if I'm forgetting a certain method or if something similar was discussed in the examples but I didn't find anything. I also googled it, and found a few answers, none of which I understood. They mostly had keywords or methods I wasn't familiar with. Anyway, here's where I am so far.
class Program { static string UpperCase(string s) { int place; string b, st1, st2,st3; char letter; for (int i = 0; i <= s.Length - 1; i++) { if (i == 0) {
[Code]....
The code compiles without any errors, but when I enter a string it capitalizes correctly for the first two words and then it starts capitalizing letters in the middle of the words.
I have been trying to get this to work for a while now - with no success.
Basically I am trying to write a function which the returns the first word of each input sentence in a single string - this is part of a larger cryptography program I am working on.
So for example, if this string was passed into the function:
"This is what I mean. Is it right? A poor puppy abandoned. Secret torturing of dogs are happening. Message: be on the watch."
It should return:
//declared in class "steganalyse" string cyphertext; string punctuation = ".?!;:'"; book is_first_word
[Code] .....
But this only returns the first word:
This
Any other way to return the first word of each sentence in a string.
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 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.
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.
The problem I am facing is that I have to output the C++ input file and display every line of code in the output, except in the output I have to convert every if, else, and while as IF, ELSE, WHILE. I tackled the first part and now its onto the 'easier' part even t
Write a program that inputs a string and then converts each 1st letter of a word in the string into capital case. An example run of the program is shown below:

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.
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 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 am building a linked list and i need to display function i have. The display function displays all the letters of the word entered instead of the word itself. below is my struct, one of my functions and the display function.
