When receiving an array from flash, in C, how do I populate that array when its size isn't constant but the values types are?
In Alchemy's documentation, the example given is:
S3_ArrayValue(arr, "IntType, ...

The last part is done. this: Write the contents to stdout upon request. but the first part, where populate a fixed sized array (not a linked list) of idtags is where im stuck. Dont't know how to use a sized array. I think that i need to save the structs in the array, thats where im stuck. |
You have the modulus going between 0 and 100, not 99. Try changing that and see if it helps.... Using % 100 will actually restrict the result to values between 0 and 99, inclusive. Suppose the rand() function returned any number from 0 to 99 on its own - then num % 100 is still num. If the number returned is ... |
Hi all, I'm working in the C language. I've been stuck for 2 weeks trying to figure out how in the world to populate arrays after reading in an input FILE. the input file has numbers and words, I need to write a loop that grabs the integers and stores them in an int array, and also store the characters into ... |

#include #include #include /* compile -std=c99 */ float getInput() { char input[32], *tptr; float val; printf("Enter any kind of number: "); fgets(input,32,stdin); errno = 0; val = strtof(input,&tptr); if ((errno) || ((val == 0) && (tptr == input))) { puts("That input is not valid! Try again..."); val = getInput(); } return val; } int main() { float array[6]; ... |

I am new to C. I am trying to make sure that the rows and column adjacent to the row and column the user input are blocked( being populated by an 'X' behind the UI so a move can not be made there. This is to stay out of the line of the queens moves. Is my for loop correct? how ... |
I am having problems with populating an array with int numbers. Since I am a new programmer, I do not know why my VS 2008 is not completing the code block. In other words when I execute the program, a blank console screen opens. I then input a number and press enter. After I press enter the program stops in a ... |
The fact you're having to beat the compiler into submission with a (char *) when calling function_matrix() conversion is a very clear danger sign. It means the function accepts a pointer to char, not a two-dimensional matrix, and that you've just got lucky in having your code work as expected when you passed a two-dimensional matrix (using the (char *) conversion ... |
I have built a program utilizing ADO to pull data from an Access Database. I am having problems taking this data which is formated as a _variant_t data type to a floating point array in C++. The following is the initial format of the array and the process that is attempting to populate this array. Can someone help me with a ... |
First of all, I don't know how your "image" is implemented, but it sure looks like you're walking off the end of your array in that for loop. (Do you know what's in data[(-1) + w*(-1)]?) Secondly, if your array Hist_r is counting occurrences of things, then its type should probably be int or unsigned int rather than float (unless you ... |
