C/C++ :: Inputting Data Into Two-dimensional Array
Apr 19, 2014So I have a two-dimensional array named temperatures[7][2] and I am trying to promt the user to input the highest temperatures for a 7 day period in the first column and the lowest temperatures in the second column. So far all I am getting when I test my code is the temperatures in the second column.
/*Intermediate23.cpp - This program inputs the highest and lowest temps. for seven days. It then displays the average high and low temps. and also diplays the highest temp. that's stored in the first column of the array and displays the lowest temp. stored in the second column of the array.*/
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
//Declare array and variable
int temperatures[7][2] = {0};
int avg = 0;
int totalTemp = 0;

C :: Inputting Data From Multiple Lines Using Scanf?
Aug 1, 2013How would I go about inputting data from multiple lines using scanf?
So far I have tried a loop and somehow checking for '' but can't seem to figure it out..
E.g I want to be able to scanf the ints below line by line and print them( if that makes sense) .
5 15 20 30 5 6
5 6 8 20 34
5 6 7
5 2
2 6 7 2 1 6
This is what i've tried so far, but am really lost!
Code:
int input;
while(scanf("%d", &input)){
printf("%d",input);
if(input == '
'){
continue;}}

C++ :: Use Value 0 To Terminate Program
Mar 20, 2013"Allow the user to enter an integer, between 1 to 9 only. You may use the value ‘0’ to terminate the program. Then display the output as follows:
Sample Run 1
Enter an integer (1-9):4
1
121
12321
1234321
Sample Run 2
Enter an integer (1-9): 20
You have entered an invalid entry, please try again.
Enter an integer (1-9): 0

C++ :: How To Terminate While Loop With Newline
Apr 24, 2012I am new to C++ and wrote some code here that is not working how I want it to:
Code:
int main() {
vector<string> distinct;
string parag;
typedef vector<string>::size_type vec_sz;
vec_sz size = distinct.size();
[Code] ....
Basically, if I run it, it takes a string, stores it in a vector string, and then outputs it to the screen as I hit enter. But then it waits for another string to be entered. How can I stop it waiting for new input after I hit enter? I tried comparing parag with and terminating there, but I am getting compiler error. I am using code::blocks.

C++ :: Inputting Text From A File?
Mar 27, 2013I have to write this program that is to store the name, address, id number, etc of a student. The data is supposed to be brought in through main and there will be multiple students. I'm not sure what commands I should use to bring it in.
EDIT: This will make more sense. In the .txt file the info will be written like
Name
Last name
Address
etc.
I need to input that and use that for the appropriate number of students.
C++ :: how To Combine A Function Call And Inputting A Value
Mar 15, 2014We're working on classes in my programming class, and I have a question about function calls.
Bascially, I have all my set and get functions set up and ready to go.
I was wondering if it was possible to have the user input a variable while calling a function.
for example
cin >> getname();
the user inputs a value that gets passed into getname.
Or does it have to be something like
cin >> name;
getname(name);
mind you all, this isn't code from my program i'm just spitballing here.
C/C++ :: Inputting True For A Boolean Variable?
Feb 7, 2014My assignment : "Input the answer as the words true or false and put the user's answer in a boolean alphabetic variable."
My code:
bool T;

cin >> T;
if (T == "true") {
cout << "Enter a whole number in decimal base: ";
cin >> dec;
cout.setf(ios::showbase);
cout << "Decimal " << dec << " to Hexadecimal with lowercase: " << setbase(16) << dec;
}
I'm not sure how to get 'true' as user-input as true for bool.
Visual C++ :: Terminate A Thread When User Push Stop Button

C++ :: Inputting Into Double-sized Vector Freezes?
Mar 27, 2013Whenever the code reaches:
matrix[atoi(tmp[1].c_str())][atoi(tmp[2].c_str())] = strtod(tmp[3].c_str(), NULL);
The app just blocks. Could it be due to a lack of RAM (since its inside a massive loop and I'm currently using an old-ass pc with 1GB RAM) or is it bad programming? If I remove that line everything runs smoothly.

As of right now, it can handle users entering characters, but what if the user enters a negative number? is there a way to check to see if what is coming in is negative before the sign gets lost in conversion to unsigned"ness"?

C/C++ :: Find Max Number Entered By User And Terminate When Negative Number Entered
Jul 15, 2014I am trying to find the max number entered by the user, and it should terminate when a negative number is entered. For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.

C++ :: Read Byte Of Char Data And Convert It Into Text String Of Binary Data That Represents Hex Value
Dec 26, 2013I am writing a program where I need to read a byte of char data and convert it into a text string of binary data that represents the hex value...
i.e. The char byte is 0x42 so I need a string that has 01000010 in it. I've written the following subroutine....
------------- My Subroutine ----------------------------------------------------------------------
void charbytetostring(char input, char *output){
int i, remainder;
char BASE=0x2;
int DIGITS=8;
char digitsArray[3] = "01";
[Code] ....
When I submitted the byte 0x42 to the subroutine, the subroutine returned to the output variable 01000010... Life is good.
The next byte that came in was 0x91. When I submit this to the subroutine I get garbage out.
I am using a debugger and stepped through the subroutine a line at a time. When I feed it 0x42 I get what I expect for all variables at all points in the execution.
When I submit 0x91 When the line remainder = input % BASE; gets executed the remainder variable gets set to 0xFFFF (I expected 1). Also, when the next line gets executed..
input = input / BASE; I get C9 where I expected to get 48.
My question is, are there data limits on what can be used with the mod (%) operator? Or am I doing something more fundamentally incorrect?
