I have same struct question for int array..

Question

paxdiablo gave the previous answer for it working with char array.. can I know how to work with int array for the same below code?

LIke:

struct encode {
    int code[MAX]; //instead char code[MAX]
} a[10];

int main() {
    int i, j;
    int x[] = {3,0,2,5,9,3,1};
    //instead char x[] = {'3','0','2','5','9','3','1','\0'};
    for(i = 0; i < 1; i++) {
        for(j = 0; j < 7; j++) {
            printf("%d", x[j]);
        }
        printf("\n");

        a[0].code=x;
        //strcpy(a[0].code, x); for char

    }
    printf("%d\n",a[0].code);
    //printf("%s\n",a[0].code); for char
    return 0;
}

Like show can this be done for int array? Thanks in advance.

Answer 1

Refer answer from your previous Question http://stackoverflow.com/questions/1911401/question-on-struct-with-char-array

• Use memcpy to copy the integer array elements.
• use %d in case you want to print integers.

Answer 2

Some questions for you, all the snippets below are from your code:

1. In the following, what's the type of x[j]. What type does %c expect?

   printf("%c", x[j]);

2. What's the type of a[0].code below? It's an array, with a predefined memory allocated to it. What to you expect the above statement to do?

   a[0].code=x;

3. Again, what is the type of a[0].code? What does %d format expect?

   printf("%d\n",a[0].code);

The answers to all the questions above are easy, or should be available in any text book.

Programming doesn't work by trial-and-error. You should find a good reference and a good textbook, and think about what you're doing.

As a first step, please answer the questions I have asked above, and hopefully you will be able to fix most of your mistakes yourself.
