RE: Why dont we give a & before reading a string in C ...
Because in C string is a array of char. and when u say:char str[16]; or char* str; //remember to use malloc to allocate address here.str gives the starting address of the string and scanf requires address of the string where it can store the rxed data.
RE: Why dont we give a & before reading a string in C ...
In C a string is an array of characters. And as known the name of an array itself points to the base address of the array , so does the name of the string.Also an '&' is used only to give the address of the following variable. Hence , when the task of '&' is being accomplished by the string name only, so we do not need an '&'
RE: Why dont we give a & before reading a string in C ...
We don't give an & before reading a string. This is so because a string is a character array. For an array, be it integer or character or any other array, declared as int a[10] or char str[20], the name 'a' or 'str' stores the base address of the array, that is the address of the memory location where the array is starting. The scanf statement requires the address of the location to store the value input by the user. Since str already stores the address of the memory location we do not need to add the & before it.
