I have a large array in C (not C++ if that makes a difference). I want to initialize all members to the same value. I could swear I once knew a ... |
Can anybody tell me the C# equivalent for this C code?

I know that you can declare an array in C like this:
int nums[5] = {0,1,2,3,4};
However, can you do this?
int nums[5];
// more code....
nums = { 0,2,5,1,2};
In other words, can I initialize the ... |
In C, i have read tat half-initialized arrays will be filled with zeros for the rest of the elements (irrespective of integer or char arrays)..
Eg: int arr[10] = {3};

I need a big null array in C as a global. Is there any way to do this besides typing out

Silly question from a new C programmer... I get a segmentation fault in the following code:
#include <stdio.h>
int main(void)
{
double YRaw[4000000]={0};
return 0;
}
Using GDB, I get the following comment:
Program received signal EXC_BAD_ACCESS, Could ...

Sometimes an array initialization in C extends over several lines, especially if the array is multidimensional. In Emacs the result of auto-indentation looks like this:
int a[N][N] = {{0, 0, 6, 7, ...

I want to initialize a array.
But ? have two different initial values in compile time.
So I want to do it in precompile time.
My code is

I was curious about how C handles array initialization. I have the following code in my program:
UChar match[] = {0xdf, 'a', 'b', '\0'};
Basically, this is initializing a UTF-16 string. UChar ... |

I am trying to initialize an array whose initializers depend on value of Enums. I take enum and then decide the initializer value, so that even if enum value changes because of addition to list even then I should be able to get correct value for the array element. I need value and state to be present in a single byte ... |

Hi all! In source.h, I define a struct and the symbolic names of the indexes: --- source.h --- typedef struct { type field1; type field2; ... type fieldm; } mystruct; extern mystruct mys; enum MYSTRUCT_INDEX { RECORD1 = 0, RECORD2, ... RECORDn, }; --- In source.c, I initialize the struct: --- source.c --- #include "source.h" mystruct mys[] = { { , ... |

say I have a structure which have an array inside. e.g. struct random_struct{ char name[10]; int month[12]; } if the array is not intialized by me, in a sense after I allocated a memory for the structure, will the integer array be initialized to 0 for all entries? (e.g. month[0]-month[11] are all equal 0). Is this compiler dependent or random? Thanks ... |

The whole program I'm trying to finish is supposed to have two large arrays, one with license plates (each as a string), and one with payments. It gets input for both in a loop but stops whenever '0' is set as vehicle type. Which means, part of the arrays will be filled, and part of them will be empty. Since I ... |

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration. |

Setting aside the fact that you can do this with standard library functions - I am assuming that this is for a homework project - this approach won't work. You can correctly convert the value of a single numeral, but once you get into two places, you run into a problem because the bases don't align smoothly. You could only do ... |
I'm writing some C++ classes for 3D graphics. One class I'm having trouble with is a 4-by-4 matrix. The problem is how to initialize a fix-sized array in a constructor's initialization list. My original approach involved an anonymous union and structure as follow: Code: class Matrix4X4 { public: // Create an identity matrix (the ellipses are not actual code). Matrix4X4() : ... |
