C :: Make Program That Takes Number Input From Tuser?
Jul 27, 2013
I have to make a program that takes a number input from the user and prints the corresponding fibonacci sequence number. For example, for the input of 3, it should print 2 since the third term in the fibonacci sequence is 2.
I am not sure how to do this so for my attempt, I used the formula found in this website. A Formula for the nth Fibonacci number
Here is the program so far. It doesn't produce the correct output.
Code:
#include <stdio.h>
#include "genlib.h"
#include "simpio.h"
#include "math.h"
[Code]....

I am writing a spell checker for a exercise for a class I am taking online. I have to load a huge text file of 143092 words into a hash table.
The program segfaults on word number 63197. Is there a way to debug this in gdb without having to step threw the function 63197 times.

I am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time
{
short year;
short month;
short day;
short hour;
short min;
};
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.

you have been tasked to write a program that takes two complex number and return their sum.However the + operator will not worl with complex numbers and you figure you need to verload the + and the assignment opeartor=.Ypu have come across the program [URL]
implement it and the client code to see it rune for the following complex numbers:
c1=3.0-4i,c2=8+4i
i have 3 files,driver.cpp,Complexnumber.cpp and complexNumber.h
complex.cpp is as follows
#include <iostream>
using namespace std;
class ComplexNumber {
private:
double real;
double image;

I'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.

I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)

So I'm trying to make a program that asks the user for a number and then prints a statement the same number of times the user entered. 3 different statements, using the 3 loops (for, while, and do while). I made the program but for some reason the statement from the do while loop goes off infinitely.

I've reached a point in "Jumping into C++" where I need to make a program that converts input numbers into their word equivalent.
So far I've made it work for numbers 0-9999. I've tried implementing 10000-99999 but there are problems with the order of the words printed (57865 would print fifty thousand seven thousand eight hundred sixty five). But besides that, the program is absolutely enormous (for me) and I'm wondering if it can be shortened. Keep in mind I can only use loops and if statements so far. Here it is:
Code:
#include <iostream>
#include <string>
void extras(int e);
void digits(int x);
void tens(int xx);
void hundreds(int xxx);
void thousands(int xxxx);
//void tens_of_thousands(long xxxxx);

So I need to make a program that counts the number of words, lines, and vowels in a program. Punctuation and white spaces are not counted in any of the counts. I have this so far and the words, and lines work and are correct but I can't seem to get the vowel count to work.
#include <iostream>
#include <fstream>
#include <cmath>
#include <cstdlib>

I'm writing an addition and subtraction calculator that takes input as: 5+6-3+2. You should be able to add or sub as many numbers as you want. I want the while loop to stop when the user hits enter. I put the getchar() function to catch the and break the loop but it is also swallowing the '-' sign, which I want to use to subtract and is instead adding the numbers with "sum+=number". How can I get around that?
Code:
#include <stdio.h>
int main(int argc, char *argv[]){
int number, sum = 0;

I have a menu for a project that takes a string input and does whatever option you specify. It works perfectly EXCEPT when it goes through the while-loop (while you didn't say quit the menu reloads). It will spew out all the text in the menu like a bulimic teenager. Then it reloads properly and asks you for an input like nothing happened. While this is not a fatal error (code still functions)...
Code:
#include <stdio.h>
#include <math.h>
#include <string.h>
double aa=0, ab=0, ac=0, sa=0, sb=0, sc=0;
char a1[13], o1[]="AAS

Write a function that takes two input arguments and provides two separate results to the caller, one that is the result of multiplying the two arguments, the other the result of adding them.Since you can directly return only one value from a function, you'll need the second value to be returned through a pointer or reference parameter.
Code:
#include "Code.h"
#include <iostream>
#include <string>
double x, y;

How do I Write a function that takes two linked list as input arguments these linked list contain numbers like this:
num1->3->5->2->NULL (assuming that number 1 is 352)
num2->4->3->9->1->NULL (assuming that number 2 is 4391)
The function should return 1 if num1 points to a linked list which represents a smaller number than the number pointed to by num2 linked list. Otherwise, it returns -1. If both linked list point to exactly the same number, returns a 0.

The problem that I am having is that , the program outputs numbers that are perfect numbers and im not sure where i can add a statement to make it so that if it isn't a perfect number it doesn't output...
#include<iostream>// allows user input/output
#include<conio.h>
#include<fstream>//data file / result file
#include<iomanip>
#include<cmath> // math function
#define in_file "data.txt"
#define out_file "result.txt"

Im trying to create a program that has the user input a 5 digit number. If it's between 10000 & 99999, it will do one thing..(just saying 'yes' for now. Outside those numbers will prompt the user to input again. However, if the user inputs the exact digits 76087, it should display 'term'.
This current code is displaying 'term' whenever the user inputs the 5 digits.
Code:
#include <iostream>
using namespace std;
int main() {
int pin;
cout << "Welcome to Movie Food
Enter your 5-digit pin code: " ;

Write a C/C++ program that reads a boolean expression in sum-of-products form and generates the sum-of-minterms form (canonical form). Use single letter to represent variables. The following symbols will be used to represent operators: NOT: ~, AND: *, OR: +. Other operators won't be used.
Examples of execution:
number of variables: 2
SOP expression: ~A+B
output: ~A*~B + ~A*B + A*B
number of variables: 3
SOP expression: x*y*z + ~x*~y + y*~z
output: x*y*z + ~x*~y*z + ~x*~y*~z + x*y*~z + ~x*y*~z
