Example text

Internally, the function processes the characters in the string until it encounters the terminator character '\0'. 0. If the length of the array is greater than the number of values in the list, then all remaining array elements are initialized with 0. If the initialization list is longer than the array, the redundant values are ignored. 0 }; In this definition, the length of the array is determined by the number of values in the initialization list. Derived Types | 51 A char array can be initialized by a string literal: char str[] = "abc"; This definition allocates and initializes an array of four bytes, and is equivalent to: char str[] = { 'a', 'b', 'c', '\0' } ; In the initialization of a multi-dimensional array, the magnitude of all dimensions except the first must be specified.

For example: y = *pFloat; // equivalent to y = x; As long as pFloat points to x, the expression *pFloat can be used in place of the variable x. Of course, the indirection operator * must only be used with a pointer which contains a valid address. A pointer with the value 0 is called a null pointer. Null pointers have a special significance in C. Because all objects and functions have non-zero addresses, a null pointer always represents an invalid address. Functions that return a pointer can therefore return a null pointer to indicate a failure condition.

The usual arithmetic conversions may be performed on the operands. • Two pointers to objects of the same type. = can also be used to compare complex numbers. Furthermore, the operands may also be pointers to functions of the same type. A pointer may also be compared with NULL or with a pointer to void. For example: int cmp, *p1, *p2; . . cmp = p1 < p2; // if p1 is less than p2, then cmp = 1; // otherwise cmp = 0. Logical Operators The logical operators, shown in Table 12, can be used to combine the results of several comparison expressions into one logical expression.
