In the above example, we used a character pointer ‘ptr’ that points to character ‘ch’. In the last line, we change the value at address pointer by ‘ptr’. But if this would have been a pointer to a constant, then the last line would have been invalid because a pointer to a c...

The characters 'L' and 'R' represent pieces, where a piece 'L' can move to the left only if there is a blank space directly to its left, and a piece 'R' can move to the right only if there is a blank space directly to its right. The character '_' represents a blank space th...

A pointer to a constant is declared as :const int *ptr(the location of 'const' makes the pointer 'ptr' as a pointer to constant. Is an array a const pointer? yes, the array name isa constant pointer tothe first element of the array, and a constant cannot be change. An array name...
We prefer using a pointer in our program instead of an array because the variable pointer can be incremented, unlike the array name which cannot be incremented because it is a constant pointer. The following program increments the variable pointer to access each succeeding element of the array ...
A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address. The general form of a pointer variable declaration is − ...

3. 如果一个多字节字符常量前面有一个L,表示是宽字符常量(wide character literal)。如L'X', L'love',当运行环境支持宽字符集时,就可以使用它们。 4. 8进制在表示的时候需要前面加一个0,如067;C/C++不允许反斜杠加10进制数字表示字符,所以8进制数表示的时候,可以省去零,如\67。
