How to search form insensitive to case sensitive? I'm trying to emulate the behavior of the function "grep" in Unix.
#include <iostream>
#include <fstream>
#include<string>
#include<vector>
#include <ctype.h>
using namespace std;
int main(int argc, char** argv) {
[Code] .....
bool simpleQuestion::checkAnswer(string guess) const {
for (int i=0;i<qAnswer.length();i++)
if (qAnswer==guess)
return true;
else
return false;
}
This is my code and what im trying to accomplish here is making the comparison of the two strings (qAnswer & guess) case insensitive. I know i need to loop through each character of each string and for each character i can use toupper and every char in each string will become uppercase and therefore case insensitive. However, im not sure how to go about this; if any technique used to loop through each character of the string and how to use to upper.
So I have started this program for class but am stuck on what to do next. Basically you need to create a function to compare 2 strings (case-insensitive). The strings shouldn't be altered and the return value should be similar to strcmp.
This is my main file
#include <iostream>
//#include <cstring>
#include <iomanip>
#include "rpstrings.h"
using namespace std;
int main () {
char Str1[20], Str2[20];
short result;
[Code] .....
I don't know if I labeled the files correct. what I need to do is to add 2 defaulted arguments which will allow the user to request that you skip spaces and/or skip punctuation when doing the comparison.
Also, how I can sort the numbers when they aren't justified with leading 0's and if they aren't in the lead string (kinda of like the natural sort).
The following Program ask a user to input a sentence. Program alphabetically sort individual character for each word.
My problem is, how do I ignore case sensitive if a user enters a uppercase letter. I try using stricmp but ran into some errors.
Below code:
#include <iostream>
#include <string>
#include <algorithm>
#include <string.h>
using namespace std;
void bubblesort(char a[]);
int main() {
char sent[50];
[Code] ....
Current output:
input: today is a great day
output: adoty is a aegrt ady
Using Uppercase:
input: Today is a Great Day
output: Tadoy is a Gaert Day
What I want:
input: Today is a Great Day
output: adoTy is a aeGrt aDy
I have to write a program to reverse a sentence like
cat
tac
but my program is case sensitive. Like if i enter sentence it gives me ecntenes(which is wrong). How to make it non case-sensitive using vectors? (I cannot use #algorithims)
// BackWardsSentence.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <string>
using namespace std;
string BackWords (string sentence);
int BackSentence (string sentence);
[Code] .....
I had been tasked to create a program that reverses a word i.e.

How can I write program that can convert an input string into a form that only the first letter of the string is a capital letter and the rest is lower-case?
View 3 Replies View RelatedI just dont know how to get my upper case and lower case equal...heres the program: Write a program to calculate utility cost for ACME UTILITY COMPANY. The company has 3 types of customers (R) residential, (C) Commercial and (G) government. Customers are billed based on the number of kilowatts used and they type of customer they are (R,C,or G).
Residential cusstomers are charged 0.25 cents per kilowatt hour for the first 500kw used, and 0.35 cent per kwh for all kw used over 500.Commercial customers are charged 0.22 cents per kilowatt hour for the first 999kw used, 0.29 cents per kwh for all kw used over 999 kw up to 1999 and 0.45 cents per kwh for all kilowatts used greater than 1999. Commercial customers that use over 2000 kw are charged a special surcharge of 100.0 in addition to the regular charges.
Government customers are charged 0.34 cents for the first 1500 kwh used(<=1500). 0.30 cent for the next 1000 kwh(1501-2500) and 0.25 cents for all kwh used over (>=2501)
in addition residential customer are charged .5% tax on the cost utilities while Commercial customers are 5% tax on the cost of utilities not including the special surcharge Government customers are not charged a tax
Code:
#include <stdio.h>
#include <math.h>
int main(void)
{
int R;
int ct;
int kwh;
int taxes;
int surcharge;
int charge
}
[code].....
the program should quit with Q and calculate the amount owed, utility charge, and surcharge
I have this code for a computer project... (store management) but the character strings are not copied on text file..

I've written a program to read inputs in a text file. The file named Input.txt contain integers 2 3 and 4. My program is as follows:
#include<iostream>
#include<cstdlib>
#include<fstream>

int main (){
int x,y,z;

the program is outputing x=2293616 , y=0 and z=0 instead of x=2, y=3 and z=4.
I need to insert my thesaurus words .txt to my c program applying BST. But I am not sure how.
Here are my file: awwwwwwww.txtthes.c
I am accepting the word from user and arranging it in ascending order like in dictionary in a file . I am doing this by comparing the user entered word from existing word in the file . All the word which is smaller then user entered word is copied to another file "temp.txt" , then the user word is printed and then the remaining word ( which are larger) from "abc.txt" to "temp.txt" . But program close as soon as i enter the second word
Code:
#include<stdio.h>
#include<string.h>
main() {
FILE *fp,*ft ;
fp = fopen("abc.txt","r+");
ft = fopen("temp.txt","r+");
[Code]....
Both file are already created before /
I got this issue to tackle which consists of using an FIR LPF filter to filter a wav file using C programming.
Till now I managed to tackle the filter part following this link: Implementation of FIR Filtering in C (Part 1) | Shawn's DSP Tutorials (I have my own filter co-efficients which have been produced using FDAtool on MATLAB and some other minor changes have been applied to match my requirements)
Now, the link shown does not compensate for files having a header. I have three wav files which need to be filtered. Thus I need to first extract the data from the header .. this was done using RIFFpad. Now that I have the data
Info from RIFFpad:
fmt -
Offset=20
ID=fmt
[Code].....
I've got this hint to start with: Each audio datasample inside the wav_files can be made up of a number of bytes and these bytes arestored in the little-endian order. Inside your program you have to change this to a big-endian order.
I'm given a project in college to use trees(AVL tree, to be specific) and file handling(not very conversant with it). But I'm not able to relate the two.
I only know that files can be used to store data. But in what way can trees and file handling be connected? I know how to implement trees but how to store it as such in files?
In interprocess communication(IPC) when processe have to share data among each other,why cant they all connect to one single file and share data with basic file handling functions such as read and write?
Why do we need
shared memory(shmget shmat(),shmdt()..etc)
and
mapped memory(mmap(),munmap()..etc)
concepts?
I have two files like original.txt and replace.txt which has equal nbr of lines in both of them.
I need to loop through these two files line by line and replace the line in original.txt to the line in replace.txt
eg :
output.txt :
1|raj|65.4|Y|
1|ramesh|65.4|Y|
replace.txt :
1|raj|65.4|Y|
Cannot be processed|1|ramesh|65.4|Y|
What I need here is when reading of output.txt reaches second line of file "1|ramesh|65.4|Y|", it has to be replaced with the second line in replace.txt "Cannot be processed|1|ramesh|65.4|Y|".
1|ramesh|65.4|Y| --> Cannot be processed|1|ramesh|65.4|Y|
After the end of loop the contents of two files should be like :
original.txt :
1|raj|65.4|Y|
Cannot be processed|1|ramesh|65.4|Y|
replace.txt :
1|raj|65.4|Y|
Cannot be processed|1|ramesh|65.4|Y|
The files can have variable number of lines but both will have same number of lines each.

I am writing to write a program and performs the following tasks
- Reading a file (txt file contains some temperature values)
- Display the temperature values (contents of the file)
- Calculating the average of the temperature values in the file.
- finds the maximum and minim value of temperature in the file.
The program is user interactive and waits for the user input and process according to his input (choice)
I have managed to complete the program and covered all the expect except the error handling for file opening and reading, although I have managed to do it for the part one part (i.e for the choice == 1)
I can repeat it for the other choices (i.e for 2, 3 ) but I do not want to repeat the code and do it in a different function or do it once for all. While making an attempt I can not handle the rest of the program and all the program turns into a mess.
#include <iostream>
#include <fstream>
#include <iomanip>
int menu();
int myChoice(char);
char inputValidating();
[Code] .....
Need Error handling for file opening and Reading that is used once, So far I have managed to do it for choice 1
Text file can be found in the attachment
I am working on an OOP assignment (text handler) which part of its description is:
Some lines of text as a story which the delimiter between each story is %%%%%
Each text loaded should only occupy the space needed for the text to fit.
It's required to use dynamic variables of type char*. To be more detailed, the text-handler must contain a vector of such char-pointers (i.e. c-strings), and the parameter in the constructor indicates how many pointers (c-strings) to be contained in the vector. Each loaded text will be represented by a number, so that the first text in the file gets number 0 and the next one gets number 1 ... etc. When you want to access a text, you request the text with a certain number, and then get a pointer in return that may be used to output the text on the screen.
My problem is first to allocate a dynamic memory like char** without defining the number of array elements (Each text loaded should only occupy the space needed for the text to fit. )and then store each story from text file (comprise of a few lines of text) into that dynamically located memory(char **)to be able to do some operation on it later.
