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.............

Introduction to C part 2

-

                                   C programming

hello friends,this is second part of introduction of C.

Identifiers:

Identifiers help us to identify data and other objects in the program. Identifiers are basically the name given to program elements such as variables,array and functions.
  • Identifiers cannot include any special characters or punctuation marks except the underscore.
  • Keywords cannot be used as identifiers.
  • Identifiers must began with a letter or an underscores.

Basic Data Types in C:

C language provide very few basic data types.

Variables:

A variable is defined as a meaningful name given to a data storage location in computer memory.C language supports two basic kinds of Variables- numeric and character.

Constants:

Constants are identifiers whose value do not change.While value of variables can be changed at any time.

Input/output statement in C:

printf:

The printf function is used to display information required by the user and also display the value of variables. The printf function takes data value , converts them to text stream using formatting specification in the control string and passes the resulting text stream to standard output.

**************************************************************************
(Normally printf Statement ka use kisi sentence ya information ko screen per display kerne ke liye use kiya jate hai. Us statement ko aap printf keyword type kerke () ka use and then inside bracket " " double quotes me us sentence or anything  jisko bhi display kerna chahte hai screen)

scanf:

The scanf function stands or use for read data from the keywords.

(if any heading you want more explain in any language hindi or english please comment below i wil create new post for that language)

Thank you .........

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  .
