Pointers are variables that store memory addresses of other variables. They allow direct manipulation of memory.

• Pointers are declared using the * symbol.

• They can be used to pass values by reference.

• Pointers can be used to dynamically allocate memory.

• Example: int *ptr; ptr = # *ptr = 10;

• Example: void swap(int *a, int *b) { int temp = *a; *a = *b; *b = temp; }

Different types of pointers include null pointers, void pointers, function pointers, and array pointers.

• Null pointers: pointers that do not point to any memory location.

• Void pointers: pointers that can point to any data type.

• Function pointers: pointers that point to functions.

• Array pointers: pointers that point to the first element of an array.

Iterate through array using pointers

• Declare a pointer variable to point to the first element of the array

• Use a loop to iterate through the array by incrementing the pointer

• Stop the loop when the pointer reaches the end of the array

Min's angle from 5 to 5:40 is 120 degrees.

• The minute hand moves 360 degrees in 60 minutes.

• From 5 to 6, the minute hand moves 30 degrees per 5 minutes.

• From 5 to 5:40, the minute hand moves 30 degrees per 8 minutes.

• Therefore, the angle made by the minute hand is 30 degrees x 8 = 240 degrees.

• However, the angle between 5 and 5:40 is only 240 degrees - 120 degrees = 120 degrees.
