Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
int main () {
I'm working with arrays and I get them column by column and need to print them. I as there a way to print in columns?
For example: I produce an array of A, B and C from a loop and then need to print them in one column and the go to the next column ....
so in the end I shall have an output like this:
A E B F C G D h ... ...
My arrays are too long (over 50K) so I cant just store the arrays and then print them. I need to produce each column array, print them and delete it and go to the next column.
# include <conio.h> # include <stdio.h> # include <stdlib.h> # include <string.h>
[Code]....
I tired changing the conditions in the for loops, but then I end up entering information multiple times and I want that to be the user's option. Do I have to change the for loops or something else? I've tried everything to get what I want but nothing works. When I print the receipt, only the last food Item that I entered prints.
I have 3 arrays (even, odd and negative), they are all different sizes, but they maximum elements they can have is 50. How do I write them to a file in this format
EVEN ODD NEGATIVE 2 3 -2 4 5 -4 6 7 -9
Code:
size = 50; //they dont all 50, its just that array cant be bigger than 50 for (int i =0; i < size; i++) { cout <<setw(5); if (even[i] != 0) { myfile << eList[i]; myfile << endl;
I have a problem in dealing with dynamic arrays. I have initialized the objects and now i want to print them.
Code: // main char* namesList[] = {"Brad Shaw","Aimen Adams","Sal Dimitry","Cristi Anreaz","Poala James"}; int idList[]={232,444,135,52,134}; Team t1( namesList,idList,5,"waqas"); t1.Print_team(); My class Team looks something like this:
[Code] ....
The print function does not work. I have to implement the print function without taking any parameters.. How should i do that ?
I'm making a simple airline reservation. I have two list boxes one has the section (A, B, C, etc) and the other rows (1, 2, 3, etc). I used two different arrays to put the values into the list box via form unload. The problem I can't seem to figure out is how can I update these seats and inform the user if a seat is taken or not. Lets say a customer takes A-1 (only seat taken). If I try to add someone else there it will inform me that seat is taken and to select another one. If all the seats are taken it'll tell me to put customer into the waiting list.
Also one more thing is that each row has 3 seats, so A-1, A-2, A-3 for example. If say A-1, A-2 are taken when I push a button show remain seats it should show A-3 only. I have a lot od struggle using arrays.
I am trying to create a program that will give me an value for a chosen from the user array ut I believe the program I've made does not recognize the values of the previous arrays. (Here is my program):
#include<stdio.h> int main() { int n; int i; int j; float c; float a[10000];
[Code] ....
There must be problem cause every value I give n(only for n=1 the answer is correct) the result is "a[n] is -inf"
I working on an assignment that processes an array of structs. In the main function I am attempting to declare an array of Author structures with 3 elements. It is supposed to be initialized to set all of the string fields (the names and book titles) to "NONE", and the double fields (the prices) to zero. This is supposed to be done in one statement, not using loops. Here is what I have.
//prototype for function to print the content of array on screen void showInfo(Author a[], int size);
[Code] .....
I was under the impression that an array can only hold the values of one data type. So doubles and strings in the same array doesn't make sense to me. However, that's the example my teacher drew up. The error keeps telling me that there are too many initializer values.
I wrote this code for a homework assignment, everything runs fine but the function void percent_votes (line 66) isn't calculating properly, it outputs 0.00 for each value. I have tried everything I can think of to try and make it work.
Here is the assignment: Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate. The program should then output each candidate's name, the number of votes received, and the percentage of the total votes received by the candidate. Your program should also output the winner of the election.
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) { int comm = 10; int targ = 5; int death; struct AI_WORDS
I am trying a program with that takes tree arrays of same even lengths and adds the values at odd indexes and save at even index of 3rd array and voice versa........
what will be the logic i have tried it a lot of time not worked................
I have a problem with my assignment. I would like to ask how to transfer positive and negative values from array temperature to arrays positive and negative?
#include <iostream> #include <iomanip> using namespace std; int main(){ int n=0, d=0, temperature[20], sum; int positive[], negative[]; float avg;
There are 7 candidates and 365 votes in total. I need to do this using an array of structures. I need to read from a text file each of the names of the candidate and the number of votes they get. At the end i need to output the winner of the election.
Each candidate gets +1 vote for their number electionCandidate[0] for each one he gets one vote and so on for the rest. 365 voters in total.
I was able to input the name for each Candidate from the text file. Now the problem is putting each vote to the corresponding candidate. Also any vote that is above 7 is a spoilt vote which i am trying to count in the above code. The code compiles but it crashes.
I am using while(!feof) but it seems that its not working or this is not the correct way.
I've been working on an assignment that deals with newspaper advertisements. I have two arrays:
categoryCode (the code for the advertisement's category such as pets, cars, etc) and numWords (number of words in the ad).
The arrays are dynamic.
My assignment has the category listed each time there is an ad associated with it and then its number of words for that ad. If this were a real-world issue I would want my output to list each category only once despite how many ads were in it, list how many individual ads are in the category, and its total number of words for the ads in that category. When using parallel arrays, is there a way to do this?
Let's say I have categoryCode with three elements {5, 5, 7} and numWords {10, 12, 15}.
How would I make the numWords add together only when the categoryCode values are the same?
I would want the output to print: Category 5 Ads 2 Words 22 Category 7 Ads 1 Words 15
rather than how my instructor is having us do it like this: Category 5 Words 10 Category 5 Words 12 Category 7 Words 15
I think I'm getting hung up because my mind is confusing the element's location in the array with the element's actual value and I'm probably making this harder than it should be. How would I compare the categoryCode values in a dynamic array? If it were a fixed size I think I could just compare categoryCode[0] to categoryCode[1] and so on, right? But in this case I'm not sure how I would go about that.
I'm working on a homework assignment that asks me to roll two die a user given number of times, find the roll sums, and a few other things. I'm working on it one module at a time and I'm running into two big problems so far.
The first problem is that my int variable rolls changes to a number within the random number generator range of numbers after I run rolldie. I got around this by making a const equal to the user entered value of rolls just so that I could continue developing the program.
My second problem is that the values of the arrays resultsOne[] and resultsTwo[] are changed after running findsum(). Why this is happening and I even tried passing them as const, but that changed nothing. We just started learning about passing arrays to functions, so there might be something big that I'm missing.
Code: #include <iostream> #include <cstdlib> using namespace std; void rolldie(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo); void findsum(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo, int tossSums[], int sizeOftossSums);
I am using matlab R2o11 in which the programming medium is c++. I am having these variables=
T=373 t0 376 V=0.09 to 1 P=T/V
I just need a result showing ... First it should take T=373 and solve the equation using all volume values. Then it takes another temperature and do the same.
I need to write a function that will merge the content of two sorted arrays of type double values. The function should not assume that both its input parameter arrays are the same length.
Here is my program so far - I know there is alot of errors and mistakes:
My assignment is writing Madd Libs game. I still do not understand how to store inputted strings or values to arrays. I need explanation of collecting inputted data to arrays.
