Write a program to read strings from the standard input, concatenating what is read into a large concatenated string next ( ok I wrote this program and it works properly ), change the program to separate adjacent input strings by a space ( problem with the second part ). In my book i learnt the difference between the string input operator and the getline function, size member function, empty , but i can't undersand how to read two adjacent strings and how to separate them.....
I am working on a program where I sort elements into alphabetical order and then when one is less than the other I swap them. I first did it by swapping the data but they want me to swap the nodes instead and I am having trouble doing that.
Node *add_node( Node *list, const string &s ) { struct Node *n = new struct Node; n->word = s; // copy string s to word n->next = 0;
// add node n to the list // the list should always be in ascending alphabetical order n->next = list; list = n;
What I have done : Created functions to accept inputs from user and read,print out adjacent matrix.
What I need : How do I start DFS in adjacent matrix so that I can output the vertices of each connected component of a graph? I'm confused with adjacent matrix and the term 'component'.
#include <stdio.h> #include <iostream> #define maxV 8 using namespace std; int V,E,x,y; int a[maxV][maxV];
I am reading a book currently on data structures in c++. The questions I have is how I would be able to swap two adjacent elements by adjusting only the links (not the data) using, a) singly linked lists, doubly linked lists.
For the single linked list which I am somewhat familiar with (by the content of the book), I would consider taking the Node A, and copying its data into a new Node temp, then re-routing the pointer from whatever connected to Node A, now to Node temp. now I want to re-route the pointer of Node B to Node temp and Node temp to whatever Node was being connected from Node B. Is this the correct approach?
I have been trying to swap two adjacent nodes for my linked list sort. Its not meant to be optimal, just meant to work. My problem is I either lose nodes or get Access Violation errors.
I'm trying to successfully run a program that calculates your BMI but, although it runs, it is not giving the the correct math. Instead, it gives me the number i've submitted as my weight as an answer. I'm using Visual Studio 2008 and the formula: weight / (height/100)*2
Here is my code
#include <iostream> #include <cmath> using namespace std; int main() { int weight; int height; double BMI;
So my midterm exam for programming is done. My program didn't run. Tried rewriting it once I got home. I am still getting an error that the program could not be run. Also, we weren't allowed to use the internet. So I didn't know how to calculate for the discounted rate.
I am using Microsoft Visual Studio 2010.
Given problem:
ABC Hotel offers 5-10% discounts depending on how much money has the user spent. If item purchase is lesser than 1000php (1USD is 43.19PHP) 5% discount is availed. Greater than 1000php then 10% discount is availed. Total price and discounted price should be displayed.
#include<iostream> using namespace std; main() { float a,b,c,d,e,f,g,h,i,j,total,discounted_price; cout<<"Please input price of first 1st item: ";
Writing a program to calculate grades... My algorithm is long, so I only posted the part that gives me trouble. When classes== 1,2,4, or 5, the program runs fine. but it terminates when classes == 3.
if (classes==3) { do { cout<<"Enter the Letter grade for 1st class. (USE CAPS)"<<endl; cin>>grade1;
I write this code for Inverse of matrix in C language . But there is error in determinant function that say "can not convert 'float' to 'float(*)[20]' for argument '1' to 'float determinant(float(*)[20])' " ....
/* a program to calculate inverse of matrix (n*n)*/ //actually one of the way to calculate inverse of matrix is : A^(-1) = 1/|A| * C(t) that A is matrix and c(t) is taranahade A
#include <stdio.h>; #include <conio.h>; #include <string.h>; #include <stdlib.h>; const int max=20; int i , j , n , k , size=0 , row , column ; float num , det=0 , inverse_matrix[max][max] , matrix[max][max] , new_mat[max][max] , m_minor[max][max] , m_Transpose[max][max];
I'm challenged to write a program which calculates the time difference between two daytime.
compiler doesn't give an error, yet the warning: "format '%d' expects argument of type 'int *', but argument 3 has type 'int' [- Wformat]" for lines 24 and 26
However, by entering the first time the program crashes anyway. so I assume I do really need some pointer to make it read from the console can you see where my problem is?
Code:
#include <stdio.h> #include <stdlib.h> typedef struct { int Second; int Minute; int Hour; }Time;
I need to make a program to calculate the business days (Monday-Friday) in a year in C. As example:
Input 2026 Output 261
I need to consider that the year could be a leap year and that every year can start with a different day. My Problem is that i dont know how to implement the right number of business days in C. I wrote down the business days in Excel for 2010-2040. I cant see any system behind it, some years have 261 business days, some have 260 or 262 but in no order.
So im trying to create a program that will calculate a shipping cost. I'm stuck on trying to calculate the actual milage and cost. Example being 1400 miles for a 2lb package would be $2 for every 500miles. so it would cost $6. But Im having trouble getting the program to round up the 1400 to 1500 so it charges the correct amount.
I know there would have to be a way to do this without programming all the conditions.
Also the course has not reached loops yet.
Code:
// This program will calculate the shipping charges.// The shipping rates are based on per 500 miles shipped. // They are not pro-rated, i.e., 600 miles is the same rate as 900 miles or 1000 miles. #include <stdio.h> #include <stdlib.h>
I have been working on a program to calculate the factorial of numbers. Part of my code is copied and modified from the FAQ about validating numbers in user input.
I have encountered a problem with the for loop that I am using near the end of my code. No matter what I do, it seems that my loop only does the multiplication of b = a*(a-1) and then prints. For example, inputting 5 will result in a print of 20, but the factorial is 120.
Code: int main(void) { char buf[BUFSIZ]; char *p; long int a; long int b; long int i;
SO Im supposed to write a program that uses arrays to calculate the sum and display it. I keep getting the error that says the sum has to be initialized.
#include <iostream> using namespace std; //Function prototype int sumArray(int); const int NUM_ELEMENTS = 5;
