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

Function Part 1

-
Hello, today we will learn about function in c programming...............

Function:

Function is self content block of code that performs a particular task. Most of the computer programs that solves much bigger and complex. Every C program can be thought as a collection of these functions. They interact with each other to accomplish a particular task function follows following approach. This approach of problem solving is called as conquer and divide strategy.

Types of function:

  1. Function prototype /declaration
  2. Function definition
  3. Function call  
Function prototype:

Syntax:
   return type  function name  (parameter list)
Ex.
int sum (int a, int b)
float mul (int, float, int)

Function prototype consist of three part-
  • return type
  • type of parameter
  • no. of parameter

Function call:

Function call by simply using function name following by a list of parameter.
Syntax:
function name (parameter list)

Function definition:

Function prototype consist of two parts functions header and function body.
return type    function name (datatype para1, ........,datatype para n)
{
body of function
}



First of all as I say that there are three part of function mean we have to follow three time rule mean first after include the header file we have to create  a function in this.
In function prototype according to syntax we write return type then  after we give name to that function and then we write variable name as parameter list in ( ) this bracket .
We use function call when we need any time that function in our program,

then we reach at function definition every important work is done here mean programming , this is also use as main function , we take input in main function and calculate in function definition then by return keyword we pass this to main function


Thank you,
if any related problem this post 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  .
