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

Introduction to C part-3

                                   C programming

Operator:

An operator is a symbol that specifies the mathematical, logical or realation operation to be performed. C language supports different type off operators which is used with the variables.

Operators in C:

  • Arithmetic 
  • Relational
  • Equality
  • Logical 
  • Unary
  • Conditional 
  •  Bitwise
  • Assignment 
  • Comma
  • Size of operator

Arithmetic operator:

Arithmetic operators take numerical values (either literals or variables) as their operands and return a single numerical value. The standard arithmetic operators are addition (+), subtraction (-), multiplication (*), and division (/).

Relational operator:

Relational operator is also known as comparison operator. This operator compares two values. Relational operator returns a true or false value.
Ex.- < , >, <= , >= .

Equality Operator:

C language supports two kind of equality operators.

  • equal ( = )
  • not equal (! = )
Comparison Operators: 
  • Greater than (>)
  • equal to (==)
  • Less than  (<)
  • Greater than or equal than to   (>=)
  • Less than or equal to   (<=)

Logical operator:

C language supports three logical operator -- logical AND( && ) ,logical OR (::) ,logical NOT ( ! ).

Logical AND:

Input         output
  X    Y        Z
 0      0        0
 0      1        0
 1      0       0
 1      1       1

Logical OR:


Input         output
  X    Y        Z
 0      0        0
 0      1        1
 1      0        1
 1      1        1

Logical NOT:


  p   0    1

~p   1     0

Unary operator:


Unary operator act on single operands.C languaeg supports three unary operators : unary minus , increment and decrement operator.

Conditional operator:

In conditional operator only one sign ( ?: )this is use in situation place.

Assignment operator:

in C this is use or assign any value in variable. and sign is ( = )
here value assign from right variable to left variable, left side variable store that value.
ex- a=b
here value of b will store in a.and b will be empty.



Thank  you,
now here intro of C language is complete these are some basic information of C, and after remember you will continue your C.
If i forget anything or you want more explain on any point please comment below.

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  .
