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

Reading and writing floating number

-
Hello guys, now here we will continue on reading and writing floate number in my last post we learn about integer number reading and writing.

Reading floating point no.:

Reading a floating point number we use scanf with format specifiers %f.


Writing floating point no.:

we use %wpf where w indicates the no. of position that a used to display a value and integer p indicates the no. of digit to be displayed after the decimal points. And printed right justified in the field off w colums leaded blanks and trailing ). The negative no.'s will be displayed with the (-) sign.

Ex.-

if value of a =56.7432

printf("%7.4f",a);

output-56.7462

print("%7.2f",a);

output-56.75

printf("%-7.2f",a);

output- _ _56.75

printf("%07.2f",a);

ouput- 0056.75

Normally you have to only remember that if you write any float no. as we show in example that 's first no. will indicate how many no. will display and after decimal which no. we use the no. will show after the decimal in output.
in reading and writing of float no. not so much only above example and how you use and when only remember.
Thank you,
If any doubt related to in this topic please comment friends.....

  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  .

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  , then print either   or   but not both. A three element array having t

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 d
