Home » Print Function - Hackerrank solution Read an integer  . Here, the value entered by the user is stored in the address of var variable. By using abs() function we can get the difference of two integer numbers without comparing them, abs() is a library function which is declared in stdlib.h – This function returns the absolute value of given integer. Python Basics Video Course now on Youtube! If you have a variable var in your program, &var will give you its address in the memory. In both cases, we are creating a pointer p (not *p) and assigning &c to it. Here, we have declared a pointer p of int type. » C++ STL Pointers are powerful features of C and C++ programming. Since pc and c are not initialized at initially, pointer pc points to either no address or a random address. To get the value of the thing pointed by the pointers, we use the * operator. Since d is -15, *pc gives us -15. Explanation of the program. We have used address numerous times while using the scanf() function. » Java Solved programs: » Cloud Computing Here, we have declared a pointer p1 and a normal variable p2. » Content Writers of the Month, SUBSCRIBE » C#.Net » Networks Writing absolute value program in C can be done using various techniques but here in this program, we show how to write a program on finding absolute value in a proper way. » CS Organizations Let's take another example of declaring pointers. » Internship abs ( ) function in C returns the absolute value of an integer.

CS Subjects: » Embedded Systems Then, we changed the value of c to 1. You can also declare pointers in these ways. Difference is quite different from subtraction, in subtraction we just subtract second number from first number and here to get difference we will subtract smallest number from largest number, so that we can get correct difference of them. This program will find the difference of two integer numbers. You have to print the number of times that the subst...
