I am writing a class Player which has several char arrays as private fields. I am trying to write a method which returns an array as a pointer, but doesn't alter the array in any way, thus the const.
Here is a snippet:
Code: class Player { private: char state[MAX_STATE_CHAR + ONE_VALUE]; int rating; char last[MAX_NAME_CHAR + ONE_VALUE]; char first[MAX_NAME_CHAR + ONE_VALUE]; int groupNumber = NEG_ONE; public: char * GetFirst() const { return first; }
Visual studio is saying that the return type doesn't match.
I came across some code and it's not clear why it is casting an unsigned char * to another pointer type only to free it right after. Here are the relevant structures:
As you can see, _Edge_Message has a *msg field, but in the function below, they cast it to the other two structure types inside the case blocks of the switch statement only to free it. What is the point or advantage of doing this?
Code: void _edje_message_free(Edje_Message *em) { if (em->msg) { int i; switch (em->type) {
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()
I like to use a Pointer to char array. And then I would like to do a Pointer Arithmetic by incrementing the Pointer. Finally I would like to see the Addresses of the Pointer to each of the char Array Elements. I had created a program below, but I am not getting any Addresses from my Pointer.
#include <iostream> using namespace std; int main () { int ArraySize; char ch[]= "This is a Char Pointer"; char* iPtr = ch;
I am trying to set a variable of type char equal to an element in an array of characters. For example:
char data[4] = "x+1"; char element; element = data[2];
This seems like a logical progression from number arrays, but when I print both element and data[2], I get data[2] as expected, but element gives a different character every time (I assume a garbage value).
Alright, so I have a code that's not giving me errors, but it doesn't seem to retain what I put into an array. Not sure If I'm missing something...
Code: #include <stdio.h> int main (void) { const char *pointer; const char alphabet[] = "ABCDEFG";
pointer = &alphabet[5]; printf("pointing to %c of the alphabet ", pointer); return 0; }
Trying to get my pointer to return the letter in the [5] spot or "F". Not receiving any errors when compiling, but I seem to get different answers every time I run it.
I am having trouble with the array pointer and with the variables. I don't seem to have the pointer set up because the additional times the array is called it is empty. Also, if I don't use integers the program drops through. where I am going wrong?
Question is in the code
/* NumClass Main.cpp ******************************************************************************************* * * Design a class that has an array of floating point numbers. The constructor should accept an integer argument and dynamically allocate the array to hold that many numbers. The destructor should free the memory held by the array. In addition, there should be member functions to perform the following operations: * **Store a number in any element in of the array
I have function that looks like this myfoo(char* Name) Now i want to compare this name to another one . But the another name is a pointer . This my code :
I understand why I think. When I am passing the reference to the array possion it is outputting everything up to the next /0. So my question is how do I stop it?
I dont have much choice as to how the output wants it:
I have this function in a class: and a private declaration: how can I copy the parameter "ProductName" to allowedProductName. I tried all combination and I can't get it to compile.
There are many questions on the web on how to fix a specific signed/unsigned mismatch, and the solution is usually just making one variable unsigned.
I have a grid (x,y) which should be unsigned, since you can't have a (-5,-3) sized grid. However, I have a Direction object which should be signed, since I can have a (-1, -1) direction. The problem is when I do something like Location_x + Direction_x > grid_x which throws the signed/unsigned mismatch warning.
I have two char variables, m_GPSOffset[13] and m_FileName[100]. When m_GPSOffset has a value assigned to it, say for instance +11:25:30. The first entry of the value, in this case +, is always stored in m_FileName. I am clueless on why this is occurring.
