When i am entering single character instead of 'miz' then it is working great. But when i am using multi character like 'miz' it is showing error output. i did this program with c++ it is working but not working in c.When i am running this program it is showing {warning] multi character constant.
Code:
#include<stdio.h>
#include<string.h>
main()
{
char a;
printf("Please Enter your First Name: ");
scanf("%s",&a);
I am trying to record some information in a file and allow user to delete a record. I am facing this message in Autos section of MVS (Error reading character of string). Here is the code:
int removeRecord(string name, int &row)//remove a record { const string data="database.txt"; fstream records; records.open(data.c_str()); const string cpData="temp.txt";
[code].....
If I delete the any row (except last roe) it works but then add a copy of last record (sometimes fully sometimes partially) at the end of the file!! if i delete the last record it does not do anything.
I am suppose to make a program that when the user is asked "Enter a Letter for the day:" if the user enters M or m then the screen will output "The day of the week is Monday" and so on until Sunday. I looked over my code and everything looks right but I still get errors saying Missing terminating character " and int function main error.
#include <iostream> using namespace std; int main() { char day; cout << "Enter a letter for a day of the week: ";
I was trying to write a character controller but when I went to add my pointer to my character I get error
C2143: syntax error : missing ';' before '*'
I've looked at all my classes involved but I don't see any errors and Visual Studio doesn't report any other specific errors. Is there any way of finding the source of this type of error?
I'm new in programming, and trying to write a code in C. The requirement is following - to write a text, and to find frequency of 1 chosen character in it. The main thing is that program should check user input (for example, I want to check if user entered "char" --> then correct, or if entered "int" --> not correct). But the program still doesn't check. So I have:
Code: #include <stdio.h> int main(){ char c[1000], ch; char i, count=0; printf("Enter a text: "); gets(c);
Double values are stored in text file. 23.5 36.8 34.2 ... My teacher told me to read them character by character and then make words, like i have to read "2" "3" "." "5" and now have to make it or treat it as word and then using atoi(). I have to convert it into double. but i dont know how to do this....
I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.
In my program, I'm supposed to read a text file (the name of which is given to me as a command line paramater, as long with an integer), and display the text in a specific format (each line can only be as long as the integer). However, I'm having trouble even reading the text file. I don't know the syntax. I'm only allowed to edit the function that does the formatting, and the code in that is
void typeset (int maxWidth, istream& documentIn)
I don't know how to 'read' the file, as most examples online are ifstream, or openFile or something like that. What I want to do is just read the first character of the file, and continuously keep reading characters until the end of the file.
So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
#include "NewString.h" using namespace ...; int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.
SLD_ttf lib and I have been following the Lazy Foo' tuts on it but the text is not appearing. I have found out that it is not loading the font as I have added in the code saying if it has failed.
Code:
font = TTF_OpenFont( "lazy.ttf", 28 ); if( font == NULL ) { return false; }
i have saved this font in the project (project name/project name/lazy.ttf).
I am trying to display images on top of my Background image gui, so like buttons an stuff but the problem is that there not showing ontop. I can only get one of them to show
// includes #include <windows.h> #include <stdio.h> #include "res.h"
I've run across this issue before, but for the like of me, I can't figure out what keeps causing it. The problem compiles and runs as expected; however in the salaried object (Employee #1 in main.cpp) the console displays the number of vacation days as -858993460 instead of the value entered.
The parent Employee class is abstract with calculatePay() and displayEmployee() being pure virtualls and with a Benefits, Salaried, and Hourly class derived from it.
The Salaried displayEmployee() and the portion of the Main.cpp that contains the salaried object follows. What causing this?
I just checking but confused with float. in that code same size int, and same type double are working but float showing nothing in printf..why?? i'm using GCC compiler int 32bit win7 os
As part of a project i want to display the speed of a small wheel on a 7 segment display. I am using a hall effect sensor to pick up the pulses of the rotation. I am not sure how to write a programe on C to calculate the RPM from this....
My question is why my on my code there is 10 zip code and i want to show the first digit, the problem is the first digit does not match the zip code for example the zip code is 45805 it should be '5' however, my code shows other number!
i have been making code of a chessgame and now sddenly computer freezed and now there's not code in .cpp file! Although my .cpp file shows size of 16kb but when i open it . there's nothing except bank file
I'm programming tic tac toe but the board is not showing numbers, and it is simply stating the winner without any input: (the win conditions are not complete, but it shouldn't matter).
#include <iostream> #include<string> using namespace std; //Write a two-player tic-tac-toe game; use enums when possible to represent the values of the board
