Question

I want to declare character array and later want to fill it. But getting error:

char line[BUFSIZE+1];
strcpy(line,"Memory is Full", sizeof(line));

Error is:

wrong number of arguments in call to strcpy. 

Is there any alternative to achive this?

Answer 1

strcpy() takes 2 arguments, strncpy() takes 3.

I think you were thinking about using strncpy, that takes destination, source, and size.

ie:

int main()
{
    char i[6];
    strncpy(i, "Hello", sizeof(i));
    printf("%s\n", i);    
    return 0;
}

>> ./a.out
>> Hello

Note: You have to append the '\0' yourself if you completly fill your char[], otherwise strncpy() will do it for you (as in my example).
