Now we would have to call swap(&x, &y) (not swap(x, y)). The following figure illustrates how it works; an explanation is below.Figure 4: The swap() function in action. (a) (b) (c)The value copied into ip will b
Explanation of the program int* pc, c; Here, a pointerpcand a normal variablec, both of typeint, is created. Sincepcandcare not initialized at initially, pointerpcpoints to either no address or a random address. And, variablechas an address but contains random garbage value. ...

Why we need data types in pointers ? The first doubt that may come to many is, why we need data types to declare a pointer variable. Well, here is the explanation. The address of a memory location will contain a data – rite? And it can be of type char, int, float etc. The dif...
Explanation Firstly, we declared (var1andvar2) and initialized the variable with values10and20. Then declared the pointer namedptr,which holds the address of an integer,var1using the address-of operator (&). *ptr,the value at the address stored inptris accessed using the dereference operator...
