C :: Scanf / Fgets Without Echo
Aug 31, 2014I am trying to write a terminal-like chat application in Linux. I would like to use a FIFO queue to print out the messages in terminal. The queue would be populated from 2 sources- stdin and messages sent from the other user over TCP. I have meet an obstacle that I cannot handle...
Lets say I would like to take user input using fgets and put it into a buffer. Then queue it if the buffer is not empty or print if it is. The problem is that when I use fgets or scanf, my input is instantly printed to the terminal..If i do:
Code:
fgets(message, 100, stdin); printf
("%s", message The string under message is printed twice :|. Is there a way to prevent this?

C++ :: Call Function Syntax To Be Equivalent To Echo
Aug 19, 2014What I want to do is simple, however I can not find a way to do it in c++ and I don't know for sure that it is possible. I want to create a function that creates a simple short-hand for printf(x); Such as:
void echo(x){
printf(x);
}
But when I call the function:
echo "hi";//I want it to look like this
//instead of:
echo("hi");// like this.
C++ :: Program Will Echo Letter (User Input) And Output Name Of The Day Of Week
Oct 21, 2012Write a C++ program that does the following:
Prompt the user to enter a day of the week as M (or m), T, W, R, F, S, and U for Monday through Sunday respectively. The user may enter an upper or lower case letter.
When the user enters a character, the program will echo the letter and output the name of the day of the week.
Provide an error trap that reads something like "you have entered an invalid letter; program aborting." Suggestion: use a switch statement with the error trap as the default condition. it is not necessary to prompt for multiple inputs.
So I know how to get the program to echo back the letter and everything. What I am a little confused about is: will I have to define all the letters as their respective day? eg. make M== Monday. And if I do have to do that how would I get it to accept Upper and Lower case letters and recognize that that letter is == monday ect. ect.
Also my main problem is the switch statement as the error trap. I have never used the switch statement, but I know what they do. I just don't really understand how I would use it for an error trap. Am I suppose to just make a case for every other letter in the alphabet other then M T W R F S and U? Even if I do that then what if the user enters a number instead of a letter?

C :: Printing Array With A New Value
Nov 21, 2013I have an array, ary[size+1] and the original values entered and then another value, x, entered. I found the index of x that makes the array nondecreasing order

But i can't figure out how to print the new array with x in it, using its index

C :: Program Not Printing Exactly
Mar 9, 2013I expected this program to print out:
Code: Enter your desired monthly salary: $2000___
Gee! $2000.00 a month is $24000.00 a year. Instead, it printed out:
Code: Enter your desired monthly salary: $2000___
Gee! $2000.00 a month is $24000.00 a year. I don't understand how it got the extra nextline in the middle.
Here is the code:
Code:

The program works well, except for the fact when it prints out the list (starting at the for-loop on line 65) each line is the same as the last, like it overwrites itself every time it traverses the while(true) loop.
C++ :: Instead Of Printing In CMD Can Print Out In CSS / TXT?
Aug 13, 2014I have previous threads asking how to make a list of words that were matched up be printed out into a .css or .txt
Is there anyway to make the words being printed out in CMD after debugging/compiling a script printed out in a .txt/.cpp file instead? CMD only has 300 lines. I need the outcome to be printed out elsewhere so more lines can be posted rather than 300.

C++ :: Printing 10 Numbers Per Line?
Nov 3, 2013I'm working on a program that prints every even number from 100 to 200. How i would be able to print 10 numbers per line?

C++ :: Printing A Binary Tree?

C++ :: Printing Text With Functions
Feb 27, 2014Any way to make a function that prints something. i wanted to make a function for
Code:
cout << " PAUSE MENU " << endl; cout << " 0. Resume Game " << endl;
cout << " 1. Commands " << endl;
cout << " 2. Controller Setup " << endl;
cout << " 3. Bottles of Beer " << endl;
cout << " 4. Quit " << endl;
cout << " What is your Choice - ";
cin >> userinput;
So i wouldn't have to retype it again in the loop, i would just call the function. but it seems whatever i try it doesn't display the text. i've tried making a function with no return time like this " Void Pausemenu(); " but that just goes blank.
Code:
#include <iostream>
using namespace std;
//This function displays different results based on the users input
int menu(int menuchoice);
int main()

C++ :: 3 Dimensional Array Printing?
Oct 25, 2013I want to make a program that asks the user for a message and then print out a large graphic of that message. For example, if the user types "he" I want to print out
H..................H EEEEEEEEE
H..................H E
H..................H E
H..................H E
HHHHHHHHHH EEEEEEEEE
H..................H E
H..................H E
H..................H E
H..................H EEEEEEEEE
(treat the periods as spaces. I only put them there because it wouldn't separate the H's correctly.)
I will loop this to continue until the user types quit.
1. How would I set this up to store the user input characters into an array?
2. How would I print out the stored data in the shape of the word?
C :: Printf In A While Loop Is Printing Twice Instead Of Once
Sep 21, 2013I have a minor issue in my program:

When I run the program, it gives:
To search for a specific word, type (Y), to use a dictionary file, type (N):
Sorry, the given input is invalid, please try again:
I can then input the number. Typing n,N,y or Y goes to the next part of the program without any problems, but if I type something else, I get:
Sorry, the given input is invalid, please try again:
Sorry, the given input is invalid, please try again:
I've fiddled about with the code for a while now, but nothing I do seems to work. What is causing it to be printed twice, or why the first getchar() is ignored.

C :: Printing A Parallelogram From Letters
Nov 14, 2013These are the instructions: read a number between 1-26 and build a parallelogram in the size (height&width) of the number entered.
Each row of the parallelogram will be built from each capital letter from 1 to the number read (max 26).for example: by entering the number 3, will be printed:
AAA
_BBB
__CCC
for the number 4:
AAAA
_BBBB
__CCCC
___DDDD
I am struggling with how to change each char in every different row, how do I print this parallelogram ?
C :: IF Construct And Printing Strings
Apr 26, 2014This code i made divided a user input into characters and non character. The problem im having is that if a mixed sentence is created, such as 32B, it will only print the 'char string' and not the 'non char string'. But when the sentence is just non characters like 32 it will print the 'non-char string'. So essentially if a mixed sentences is created both of the strings won't be created or printed.(This is only a function by the way).
Code:
Count_chars( char Input[]) {
int i;
for(i = 0; Input[i]; i++) {
if((Input[i] <= 122) &&(Input[i] >= 97)){
printf("Char %c ",Input[i]);
Char[i] = Input[i];
