We are programming a ST269 microcontroller which has two IR distance sensors. To calibrate these sensors we made one table for each sensor with the distance we measured and the corresponding ... |
Basically, I have three arrays, CQueue (2D-array), PQueue (2D-array, the same number of arrays as the CQueue, but with each array containing twice as many values) and CC (standard array which ... |
I have a one dimensional array, how can I store information in a two dimensional array, I have tried the following code, but it doesn't works fine...
for (y=0; y<gar; y++) ...

strcpy() starts copying from the address of the second argument and doesnt't stop until it hits a binary zero. Therefore, using strcpy() in this fashion will never guarantee that 10 bytre are copied. Is using strcpy() a homework requirement? If not, I sugget using strncpy() and tell it to copy only 10 bytes. Since all arrays are one dimensional, you need ... |
Code: #include #define SIZE 5 #define SIZE2 5 #define ROWS 2 void transarr4(int *(*(arry)), int * arry2, int row); //Pointer Notation (Multiple Dimension Array) int main(void) { int arr[SIZE] = {100,200,300,400,500}; int arr2[ROWS][SIZE2] = {{},{}}; int *(*(arr3)) = 0; transarr4(arr3,arr,ROWS); //Pointer Notation (Multiple Dimension Array) return 0; } //==================================================================================================== // Pointer Notation (Multi-Dimension Array) //==================================================================================================== void transarr4(int *(*(arry)), int * ... |
Thanks for the info, but how could i copy the null sign too? I played around with adding it to the end of the array and it didn't give me the weird output anymore (just the output i wanted). Maybe not just copy it, but at least get the position where i should add it. |
I am currently trying to copy the contents from a single dimension array to a multiple dimension array using pointer notation. I though am having problems doing so. Can someone out there show me how to program a multiple dimension array that will take from a single dimension array? Listed below is sample code that I am trying to get to ... |

Hello, I am proberly asking a very silly question now to some experienced C programmers might feel, but im still learning my way through. I know argv (command line contents) is a multi d array of chars like an array of chars of chars. I really want to know how would i copy all of those contents to another multi d ... |
I have been trying to figure out how to copy the contents of lineBuf and place them into the slines second array(512)... but have been unable to locate any documentation/tutorials on how this would be accomplished. I have tried using the strcpy and strncpy but all I get are segfaults. I am sort of at a lost since my knowledge of ... |
i got one question is: i got data from outside and i took the data to compare in the compare function.after comparison.i know the data is belong to which catagory and will print out the name of category.but i hav to save the name of category in one array as my database.so that,when i look into the database.i can know the ... |
i had posted the question.now is the code: void compare(double la,double lo) { char *msg1="Road A"; char *msg2="Road B"; char *msg3="Road C"; char *msg4="On The Way"; if(la<=119.805000 && la>=119.794000) { if(lo<=10346.485000 && lo>=10346.440000) { puts(msg1); //strcpy(save,msg1); printf("\n"); save(msg1);//call save function to save this msg } else { puts(msg4); //strcpy(save,msg4); printf("\n"); save(msg4); } } if(la<=119.852000 && la>=119.830000) { if(lo<=10346.480000 && lo>=10346.430000) { ... |

I had such code to copy three 2D arraya around by using pointers like below, but it seems all three pointers are pointing to the same memory address. How can I get it correctly? float **U_past, **U_future, **V_past, **V_future, **U_pp, **V_pp; In construct : U_past = new float*[a]; //a=100 U_future = new float*[a]; U_pp = new float*[a]; for(int i=0; i |
