C :: Which Data Type Have To Enter To Get 12 Digit Numbers
Jul 8, 2013
I've seen some threads that include the information about what data types one has to use usually to put a number of 12digit. But honestly speaking none of them works for me & it takes me a lot suffering about the data type. Even I've googled but I didn't get any specific result.
So, which data type I'd have to use to enter 12digit number.
I'm writing a code to find the largest prime factor of the number 600851475143
Enter as many numbers as you want as long as the user doesn't type 'e' to exit.
Problem: When I enter a number, it works fine, but if I enter e then it'll go in an infinite loop since the letter is being stored in an int variable. How can I (when I press 'e') make it convert to a char to make it end the program?
#include <iostream> using namespace std; int main() { int num; cout << "Enter a number or press e to exit:";

Our class has just started c++ and we have not learned arrays and classes yet, so I'm guessing there is a way to do this without it? Or no?
I am trying to write up something to have a user to enter a four digit number. Only four digits, Ex: 0001, 0116, or 9999. There is no getting around the selection 0001 or 0002. I understand if not done correctly, the first three 0's will be ignored.
I've been just playing around with what I have below but I just don't remember how to do it nor can I find a good example online to figure it out. I know it is not correct just typing to try to remember. I am aware that it is gibberish right now, this is just me brainstorming.
int number; cout<<("Please enter the four digit number(Ex: 0001): "); cin>> setw(2) >> number; cout<<)"Please enter four digit date. Two digits for month and two digits for year: "); cin>> date; if (number< || number > 30) cout << "Invalid choice. Try again." << endl; cin.clear();
this write in text box numbers from keypad for example
5 0 2 4 9
After each typed digit, here is a underscore line waiting for the next to type next digit. I want to prevent users to type zero as the first digit in value.
// this program gives random number output #include <iostream> #include <cstdlib>// contains function protype for rand #include <iomanip>// for setw using namespace std;

what is the effect on output of program of different numbers input to the int data type named seed*/
if i have two integers, say number1 and number2, stored in arrays where each index is a digit of the number (i.e. if my numbers are 321 and 158, then number1 = {3,2,1} and number2 = {1,5,8}), can i find the remainder of number1/number2? assume number1 > number2.
basically we were asked to make a program that will print everything before the user hits the enter button. we cannot use fgets and we have to use pointers here.
not sure what exactly to do. We were told not to use fgets cause it's so easy and we need to incorporate pointers in this project..
My assignment is : Please use C type strings ( array representation of strings). Write a program that will ask the user to enter a string. It will then regard that string as a worked-on string and allow the user to perform the following editing functions on it:
s – search i – insert a – append d – delete a – append d – delete r – replace e – exit s – search
This option will allow the user to search for a specified string in the worked-on string. If the string is
found, it will display the starting index (position) of the searched string in the worked-on string.
here is what i have so far.
#include <iostream> #include <cstring> using namespace std; int main() { char a_string[80];
I'm having some problems with changing an array of numbers of type char to type int. Every time i try to sum 2 array indexed values it returns some letter or symbol. Also, if i change the type of the array in the functions the compiler gives me an error message. I would also like to add that the problem requires that the first two arrays be char so each individual number gets assigned to a different value.
My current code is:
Code: #include <iostream> void input(char a[], char b[], int& size_a, int& size_b); void convert(char a[], int size); void reverse(char a[], int size); void add(char a[], char b[], int c[], int size); int main()
Write a function which will take 3 arguments. The function needs to return a new number which is formed by replacing the digit on a given position in the number with a digit which is carried as an argument (the position in the number is counted from right to left, starting with one). Write a main program which will print the newly formed number.
Examples: A function call of 2376, 3 and 5 should return the number 2576 A function call of 123456, 4 and 9 should return the number 129456
What I succeeded to do so far: Figure out the logic for swapping the digit and write working code for it (in the main function).
What I failed to do so far: Write a function which will return the desired result.
What is my problem: I tried writing a function to do this, but as you see from my calculations, my result is divided in 3 parts. I don't know how to return more variables from a function.
Code:
#include <stdio.h> int main() { int inputNumber, swapPosition, swapDigit; scanf("%d%d%d", &inputNumber, &swapPosition, &swapDigit); int i, numberPart1 = inputNumber; for (i = 1; i <= swapPosition; i++)
I want to do simple program to capture some 5 surnames of people(employees) - using array and pointers. Well I understand a bit of arrays and I know how to loop through.
How can achieve this? This holds the key to my understanding how pointers work and can be used with char or strings.
Having problem with my code. i keep getting an error towards the bottom of the code. i need the user to enter a word. and with that word convert it to numbers. once i have convert it if it is bigger than 20 i have to add the two digits together and get print out the array that response to it.
example" ALEX A=1 L=12 E=5 X=23
1+12+5+23= 41 //since its bigger than 20 you add 4 and 1 together so it will be 5. after that you print the 5th element of array
#include <iomanip> #include <iostream> #include <string> using namespace std; int main() { string name;
fprintf(stderr, "Data is %s when first entering ins_llist loop. ", data); q = malloc(sizeof(struct lnode)); if ( q == NULL ) return(NULL); }
[code]...
Trying to figure out a way to sort as i enter my data into the llist. What is in red and blue is what I've been messing around with to try and see if maybe i can get it to sort but it is not. When i flip sign, the order changes opposite, but i cant see how to sort each item as i go. Maybe i am too tired right now, lol, been working on this program for what feels like 30 of the past 24 hours haha.
Create a program that will ask the user to enter a decimal value (1-999999) then display its corresponding binary numbers. Repeat this process until the value entered is equal to 0. Use the following Function Prototype:
void BinCodes(int value); Sample Input/Output: Enter a Decimal: 35 Binary: 100011 Enter a Decimal: 184 Binary: 10111000 Enter a Decimal: 0
I have a small program to calculate the value of salary. I want to user to be able to enter more than one user using array and finally calculates the average salary of all users.
Here is the code
Code: #include <iostream>#include <conio.h> using namespace std; int main() { const int months=3; double net_pay; string EmpName;
I'm trying to solve the ferry loading problem using two queues. My problem is I can't enter in data after the first set is scanned in, I'm assuming there is a problem with my loop, such that the scan function doesn't get called after one iteration. In the example I marked the data I can't enter. An example correct input would be:
correct input: 1 - can enter data20 4 - can enter data 380 left - can enter data 720 left - can't enter data 1340 right - can't enter data 1040 left - can't enter data
Okay, so my assignment for my C class is to generate a program that will allow the user to enter data for a stock and calculate the amount of stocks that ended up being positive, negative, and neutral.I tried to do this using one stock, here is my code;
I want to create a new data type called an inf_t. It's basically infinity (which for C++ is 1.7e+308). The only reason I want this is because I want to overload the cout << operation to print out INF/inf. Should I do this in a struct?
