const int days_per_month[] = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; Is it ok to declare the array in this manner or is it bad?
And i have to ask the user for a date to enter in my program. So should I use scanf or should I store the date in a string and then use sscanf. I have to check for valid input for everything like day, month, year etc. I did it as below..
We have been assigned to create an iTunes library. Everything compiles in my other .h file but my main is not happy with my object declaration. It keeps stating "primary expression before '{'". Here is my main code:
I'm writing this program that basically interprets the rottentomatoes website. I am however having a problem declaring if it is rotten or fresh according to the rating the user enters.
I'm outputting it here:
void PrintAll(const string titles[], const int ratings[], int count) { WriteLine('=', 50); cout << "PRINT ALL" << endl; WriteLine('-', 50);
[Code] .....
And here is my condition:
string RatingToString(const int ratings[], int count) { string rank; for(int i = 0; i < count; i++) {
[Code]....
Here is the output:
1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950 ================================================== MENU 1. Add Movie 2. Print All 3. Exit -------------------------------------------------- Enter 1-3 : 1 Title : Hitch Rating : 90 ==================================================
[Code]....
My condition works when there is only one movie, but when I add more, it gives it the new movies "ROTTEN" or "FRESH" rank.
class Hallway { private: //--------------------------------------------------------------- // DO_04: Declare a Light array of size MAX_LIGHTS // Hint: look through the methods below to find the name to use // for the array //---------------------------------------------------------------
int numLights; int lights[MAX_LIGHTS];
[Code] .....
I keep getting the error " this.lights[i] is not a struct or class and so you cannot use '.' " on line 34.
How am I supposed to define my lights[] array? I can't modify anything except directly after each comment block.
1. Declare an array that will hold 3000 numbers 2. Initialize this array by assigning a random number to each element in the array 3. Traverse the array, modifying the current contents of each element in the array so that each value now lies between -3000 and 3000 inclusive 4. Traverse the array to compute the average value of all elements
I have never worked with arrays before and am lost!
I am new to C. I've been trying to use C to code some statistical functions originally coded in R. I've encountered an interesting phenomenon. In the function foo1, I declared the array v1v2b using an actual value 1999000. The function runs fine when I call it in R.
Code: void foo1(double *x, double *y, int *nsamp){ int i, j, k, oper=2, l; double* v1v2=malloc(sizeof(double)*((*nsamp)*(*nsamp-1)/2 + 1)); outer_pos(x, y, nsamp, &v1v2[0]); double v1v2b[1999000]; //<-------HERE for(i=1; i<= 1999000]; i++){ v1v2b[i-1]=1; } }
However, in foo2, I first create an integer variable called index, and store the value 1999000 in it. I then use it to initialize the same array. When I tried calling this function in R, it either led to a stack overflow error, or completely crashed R.
Code: void foo2(double *x, double *y, int *nsamp){ int i, j, k, oper=2, l; double* v1v2=malloc(sizeof(double)*((*nsamp)*(*nsamp-1)/2 + 1));
I'm making a flash card type console application using visual studios 2013. The flash cards contain character that I can display using unicode. So far I am looking at about 200 characters across 2 unicode blocks which I don't want to hard code into my arrays. I thought of initializing my arrays using a loop. The only problem is I don't know how to add in hexadecimal. So is there a way to initialize my array without having to input 200 values my self? Also is hexadecimal addition possible without me having to write a function for it?
This code i made divided a user input into characters and non character. The problem im having is that if a mixed sentence is created, such as 32B, it will only print the 'char string' and not the 'non char string'. But when the sentence is just non characters like 32 it will print the 'non-char string'. So essentially if a mixed sentences is created both of the strings won't be created or printed.(This is only a function by the way).
I've a problem with the map construct. I wrote this class in which there are maps:
class Features { private: map<const string,GenericFeatureContainer*> featuremap; map<const string,GenericFeatureContainer*>::iterator it; int size; public: }
This code i made, utilizing the type casting construct, isn't outputting what i wanted. The output for 'Dollars' and 'Cents' are returning '0' for both. instead all i want it to do is seperate the two. for example changing the float value of amount to an integer, giving a dollar value.
How to construct a simple hash function ? When the program executes, it will ask for your name. Type your name and it will print out a "hash code" (a number) from that name.
have a problem with my code (I wish for answer with code). The conditions I have to grant:
- **Only** a pointer to an object must be saved in a **standard** class vector (e.g vector<ShapePtr>) - Base class must be a polymorphic class (I call this class ShapePtr) - I **must** have a deep copy process - Constructor is **not** suppose to do a deep copy - **clone()** is suppose to do the deep copy
Here is the code **provided** to me:
main.cpp int main() { typedef shared_ptr<Shape> ShapePtr; vector<ShapePtr> shapevec;
If I have an integer variable like int a=9 then in the switch case If i write :
switch(a) { case 4+a: printf("hii"); }
Then why is this statement a compile-time error that variables cannot be used inside a case statement why does the compiler not subtitutes the values in place of the variables.
This code i made is a cent converter from 5 to 95 cents. The problem i'm receiving is when the 'cents' function is sent back to the 'main' function it only prints one line. It seems to just print the first if construct that complies with the statement. Is there anyway i can have this function print multiple cent values? For example if 60 cents was entered it would only print '50c', and i want it to print '50c' and '10c' instead.
Code:
#include <stdio.h> int x; void check(int x) { if( x < 5) printf("Less then 5 cannot be calculated "); else if(x > 95)
I am trying to construct a program without a main function that outputs stars but at the same time outputs the number and a colon after the number but before the number of star. This is the coding i have so far.
I'm trying to read a "pointer-based" maze .txt. The first letter in each row corresponds to the room letter...then the letters that follow are North node, East node, South node, and West node respectively. The asterisk indicates an empty room or not a valid option.
Here is what I have come up with, what is happening is after the file is parsed by read_maze it is calling my is_empty function indicating that there is no maze because it doesn't go into the else statement here.
I've attached a sample input file:
maze.txt (130bytes) Number of downloads: 19
We can't assume the rooms will be in order alphabetically A - Z, We are expecting a maximum of 12 rooms and there is a space between each letter or asterisk.
void Maze::read_maze(string FileName){
string line; ifstream inStream; inStream.open(FileName.c_str()); int test = inStream.peek(); int i = 0; if (!(inStream.fail())){ while (!inStream.eof() && test != EOF){
I need to construct Truncated Gaussian distribution in the range of (5-20 microns), specifyed by initial standard deviation.
Particularly i need input which comprises of minimum value(5 microns), maximum value(20 microns) and standard deviation of (5,10,20 etc..). In this regard i tried with Box-Muller but it doesn't fulfuil the goal.
I can't get my code to compile, i need to read in lines from a file and store them in variables. Then i have to construct instances of my class for how many lines there are in the file and take those variables into them.
