See a problem in else if statement

Dangling else problem

Hello, This problem comes when we use else if statement and do some mistake more describe is given below......... Dangling else problem: One of the major problem with nested if is dangling else problem. The problem arises when both outer if statement inner if statement might pair with common else statement. Thus the compiler is not able to judge to pair the else with which statement. The solution to this problem is given by the compiler that it pairs else with the recent if thus sometimes giving wrong result.                                           Hence the programmer should put early bracket wherever required. This post is may very short because my only aim was to describe this problem. Thank you, Keep supporting.............

Rule of function declaration and type of variable

-
Hello guys , today in this my post i will tell you some basic rule of  function declaration and how many types of variable we use in function .

Rule of function variable:

  1. Find declaration needs to be ended using semicolon.
  2. Return type is optional.
  3. Type of  parameter & number of parameter are combings called parameter list. The parameter C in the list may or may not have parameter name.
  4. No parameter can have some names even parameter name and function name cannot be same.
  5. A function need not be declared if it is defined before it is called.
Ex. Void add ( int , int )
The above declaration declare a function name and with two parameter of type of int and return type of void ( function does not return ).
 Function header is same as function declare but without a semicolon,It consist of return type , function name , parameter type and no. of parameter.

Variable:


There are two types of variable in function-
  • Local variable
  • Global variable

Local variable:

 It is a variable that is defined inside a function and can not be used outside that function.

Global variable:

It is a variable that are declare  outside any function and where values can be used in any function without posting it to any function.

Parameter:

Parameter are used to pass values to called function and are also use to receive values from calling function.There are three type of parameter 
  • Formal parameter 
  • Actual parameter

Actual parameter:

Actual parameter are those parameter which have the original copy of parameters. The parameter passed in the function call are called actual parameter.Scope of actual parameter are only with in called function.

Formal parameter:

Formal parameter are those parameter which have duplicate copy of parameter.The parameter in function header as called formal parameter ( scope is within called function).

Permutations of Strings hackerrank solution in C || Permutations of Strings

-
  Permutations of Strings Strings are usually ordered in lexicographical order. That means they are ordered by comparing their leftmost different characters. For example,   because  . Also   because  . If one string is an exact prefix of the other it is lexicographically smaller, e.g.,  . Given an array of strings sorted in lexicographical order, print all of its permutations in strict lexicographical order. If two permutations look the same, only print one of them. See the 'note' below for an example. Complete the function  next_permutation  which generates the permutations in the described order. For example,  . The six permutations in correct order are: ab bc cd ab cd bc bc ab cd bc cd ab cd ab bc cd bc ab Note:  There may be two or more of the same string as elements of  . For example,  . Only one instance of a permutation where all elements match should be printed. In other words, if  , the...

use of getchar and putchar

Hello guys today i will tell you in this post , use of putchar and getchar............                          C programming Input and output functions: Generally we use printf and scanf as input output functions respectively  but there are various functions available for input and output. Input and output for character: Reading a character: In general scanf function is can be used to input a character but instead of that we can use getchar function. syntax: variable name=getchar();                  There are some functions that are used to test a character based on some requirement - isdigit (ch): It returns a non zero when character digit is digit otherwise returns a 0 value.                                                  ...

Libraray Fine Hackerrank solution in C || Balanced Brackets Hackerrank solution in C

-
  Library Fine Your local library needs your help! Given the expected and actual return dates for a library book, create a program that calculates the fine (if any). The fee structure is as follows: If the book is returned on or before the expected return date, no fine will be charged (i.e.:  . If the book is returned after the expected return  day  but still within the same calendar month and year as the expected return date,  . If the book is returned after the expected return  month  but still within the same calendar year as the expected return date, the  . If the book is returned after the calendar  year  in which it was expected, there is a fixed fine of  . Charges are based only on the least precise measure of lateness. For example, whether a book is due January 1, 2017 or December 31, 2017, if it is returned January 1, 2018, that is a year late and the fine would be  .
