[C] copy a table Solved

Question

Hello,

I have code with functions, the goal is to fill an array with numbers, then display it,... and finally
copy it to another array.
I don't know how to do it, I tried with a function and it doesn't work.

If anyone has an explanation...
Thank you in advance

You can use the memcpy() function  #include  int Tab1[10], Tab2[10]; memcpy(Tab2, Tab1, sizeof Tab2);

ps: here is the code  #include  #include  #define tmax 5 //function prototypes void display(long *array, long maxSize); void encode(long *array, long maxSize); void sum(long *array, long maxSize); void average(long *array, long maxSize); void copy(long *array1, long *array2, long maxSize); int main(int argc, char *argv[]) { //variable declarations long t[tmax]={0}; long t2[tmax]={0}; encode(t,tmax); display(t, tmax); sum(t, tmax); average(t, tmax); copy(t,t2, tmax); system("PAUSE"); return 0; } /*display function*/ void display(long *array, long maxSize) { int index; for (index=0; index

Which language are we talking about? Can you tell us a little more about it?

limbergh · Answer

Well, yes, I forget the most important thing... It's C language.

Re, what is sizeof used for? And memcpy? I know strcpy, what is the difference?  Thank you in advance for your explanations.

OrionS · Answer

The strcpy function is used to copy a string into another, while memcpy takes three parameters, the first being the destination array, the second the source array, and the third the number of bytes to copy...

Hello,  There is no copy error, it works very well. However, it would be better to do:  void copie(long *tbis, long *tbis2, long tmaxbis) { int ibis; for (ibis=0;ibis<tmaxbis;ibis++){ tbis2[ibis]=tbis[ibis]; printf("values of table 2: %ld
", tbis2[ibis]); } }  Otherwise, you will only display one value from your table tbis2 --  Google is your friend
