C++ :: How To Stop Outputting Data Based On A User Input
Sep 27, 2013how to stop outputting data based on a user input. The text file is as follows:
1. a
2. b

int main (){
string line;
int search;
cout << "Enter a number from 1-3" << endl;
cin >> search;
search++;
ifstream myfile ("example.txt");

What I want to do is to just output number 1 (the whole line) if the user enters number 1. However, I get an error on the second condition w/c is the "&& line!= search"
C++ :: Reading Contents Of A File From Command Line
Feb 7, 2014i would like to read the content of a text file data.txt (line by line ) directly from the command line using this command: a.exe < data.txt.

C++ :: Store User Input Then Display Array Contents?
Jan 10, 2015I'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.

C++ :: Zero In List Contents And Multiset Contents
Apr 24, 2015HTML Code:
So I insert values from a vector into a list and into a multiset, and I noticed zero is added to their contents! I had to do a whole lot of debugging to find out where the error was, how can i stop this thing? Code which generates such error...
infact i checked the content of vector ups to be sure that there was no zero in it, but after loading into list combi_t * head, it seems like there was a zero added and this is giving me errors when i call function master_roller...
Code:
void ins(combi_t * &testa, int &numero, int &num, int &no)
{ // if (ricerca(testa, numero) == 0)
//{
combi_t *temp = new combi_t;
temp->val0 = numero;
temp->val1 = num;
temp->val2 = no;
temp->nextPtr = 0;

View 5 Replies View RelatedC :: Have One Line Of Input Trigger Actions?
Nov 26, 2013I want the phrase "BUY TICKET" to trigger something, i'm thinking an if statement, and then assign the number after the phrase to another variable. There will also be other commands entered from the input file such as "BUY RAFFLE' "TOTAL REVENUE" on the following lines. Sounds like I need to compare a string(?) to a constant phrase, and if they match have it run the specific code?
Code:
//scan in from file
fscanf(ifp, "%c", &input);
if (input == 'BUY TICKET'){
//Run this
}

C :: Why Not The First Line At The Standard Input Read
Mar 21, 2013Here's my code, it's for a poker hand evaluator
input:
'ad 2d 3d 4d 5d...
...4s 5s 6s 7s 8s'
I think it should go through all the 10 crads and disply the name of each card, but it seems to only do it for the second hand
Code:
include <stdio.h>
#include <ctype.h>
int main( void ) {
char inputtedhand[64];
int z=0, counter=0;

C :: Pointers Array De-allocation And Input In A Line
May 24, 2013I have three questions concerning the below code I have written, which is expected to do basically as the attached diagram illustrates:
Code:
#include <stdio.h>
#include <stdlib.h>
double getAverageGrade(int studentGrades[] , int size);
int* getStudentInfo(int * numCourses);
int main()
[Code] ...
(1) How may I display the averages to 2 decimal places, namely why doesn't %.2lf work? The program gives 89.00 for 89 and 90, for instance.
(2) How may I read the number of courses and the relevant grades in a row for each student?
(3) How may I free (de-allocate) my array of pointers, namely grades? Does it suffice to use free(grades)?
C :: Use Fgets And Sscanf To Read A Line Of Input
May 21, 2014I'm new to C/C++. I am attemping to use fgets and sscanf to read a line of input, and confirm it is a positive number.My code works great, except for the case of a negative number. When I enter a negative number, my while loop seems to run infinitely, with stdin providng the same input over and over again.
Here's the code snippet:
Code:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#define TEXT_LEN 64
void foo() {
char* inStr = (char*)malloc(sizeof(char)*TEXT_LEN);
memset(inStr, 0, TEXT_LEN);
}

C++ :: Using Getline Multiple Times On One Line Of Input
Sep 15, 2014I've been stuck on this for hours, and have scoured the internet for any insight on this particular issue with no luck.
I'll simplify the problem here. I have a lines in an input file:
John Smith 1234 Main St New York
Carol Thomas 5678 5th Ave Columbus
...
and I am reading into character arrays using code like this:
infile.getline(name,20);
infile.getline(street,15);
infile.getline(city,10);
but when I print the output using something like this:
outfile << "Owner Name: " << name << endl;
outfile << "Address: " << street << city << endl;
(let's pretend I included spaces between the address components, which I omitted to save space)
I get an output file of:
Owner Name: John Smith
Address:
The output stops after the name variable, which I believe is stored correctly. I don't think anything is storing in the address pieces, this is the problem.
I think it's because I'm not using getline() properly in this case. Can you string together multiple getline()s like that?
If this was my design, I'd read in strings instead, but that is not possible in this case.

C++ :: Record User Input But Combine It With Command Line Arguments?
Aug 15, 2013I want to be able to write a program where I can record user input but combine it with command line arguments.

Jan 23, 2015I'm trying to create a program that takes an integer input and displays each digit on a new line from right to left.
An example of this would be:
Enter an integer: 657
Digit (1): 7
Digit (2): 5
Digit (3): 6
So far I have this:
#include <stdio.h>
#include <math.h>
int main() {
int i, input, output;
printf("Enter an integer: ");
scanf("%d", &input);
if(input == 0)
printf("Digit (1): 0");
[Code] ....
It works perfectly fine, but I just learned that I am not allowed to use the #include <math.h> so I have to take out floor, log, and pow.
I'm pretty sure I have to do some sort of while or for loop to get the results, but how to do it.
