## Conditional Statements in C – HackerRank Solution Explain Video :

Conditional Statements in C – HackerRank Solution , We Discuss About That Conditional Statement Hackerrank Solution in C.

## Problem :

• Objective
• Output Format
• Input Format
• Sample Input 0
• Sample Output 0
• Solution

## Objective :

if and else are two of the most frequently used conditionals in C/C++, and they enable you to execute zero or one conditional statement among many such dependent conditional statements. We use them in the following ways:
1. if : This executes the body of bracketed code starting with statement1 if condition evaluates to true.
```if (condition) {
statement1;
...
}
```
1. if – else : This executes the body of bracketed code starting with statement1 if condition evaluates to true, or it executes the body of code starting with statement2 if condition evaluates to false. Note that only one of the bracketed code sections will ever be executed.
```if (condition) {
statement1;
...
}
else {
statement2;
...
}
```
1. if – else if – else : In this structure, dependent statements are chained together and the condition for each statement is only checked if all prior conditions in the chain are evaluated to false. Once a condition evaluates to true, the bracketed code associated with that statement is executed and the program then skips to the end of the chain of statements and continues executing. If each condition in the chain evaluates to false, then the body of bracketed code in the else block at the end is executed.
```if(first condition) {
...
}
else if(second condition) {
...
}
.
.
.
else if((n-1)'th condition) {
....
}
else {
...
}```

Given a positive integer denoting n, do the following:

• If 1<=n<=9, then print the lowercase English word corresponding to the number (e.g. one for 1, two for 2, etc.).
• If n>9, print Greater than 9.

## Input Format:

The first line contains a single integer denoting n.

5

five

8

eight

44

Greater than 9

## Solution Solution :

#include <assert.h>
#include <limits.h>
#include <math.h>
#include <stdbool.h>
#include <stddef.h>
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
char* n_endptr;
const char *numbers[9] = {“one”, “two”, “three”, “four”, “five”,
“six”, “seven”, “eight”, “nine”};
int n = strtol(n_str, &n_endptr, 10);

if (n_endptr == n_str || *n_endptr != ‘\0’) { exit(EXIT_FAILURE); }

if ((n > 0) && (n < 10))
printf(“%s\n”, numbers[n-1]);
else
printf(“Greater than 9\n”);

return 0;
}

size_t alloc_length = 1024;
size_t data_length = 0;
char* data = malloc(alloc_length);

while (true) {
char* cursor = data + data_length;
char* line = fgets(cursor, alloc_length – data_length, stdin);

if (!line) { break; }

data_length += strlen(cursor);

if (data_length < alloc_length – 1 || data[data_length – 1] == ‘\n’) { break; }

size_t new_length = alloc_length << 1;
data = realloc(data, new_length);

if (!data) { break; }

alloc_length = new_length;
}

if (data[data_length – 1] == ‘\n’) {
data[data_length – 1] = ‘\0’;
}

data = realloc(data, data_length);

return data;
}

Firstly, You have to Copy The Code Here and Go to Your Conditional Statements in C – HackerRank Solution Questions Problem. Then You Have to go Submission Page. Now You Have Pasted this Copy Code and Run This Code by Compiler. You Can See All Task Should be Done. All Private and Public Cases Passed. Then Submit Your Code Finally.

## What is #Include<stdio.h> ?

#include<stdio.h> is used to included header file in c programming language. It is a Mandetory. It is also Compiler Directives to Include INPUT/OUTPUT related function in our Program. The stdio.h is a file with “.h” extension which is contain the prototypes [not definition] of standard input-output functions used in c program.

## What is int main() ?

‘int main’ means our perform must come thusme whole number at the top of the execution and that we do so by returning zero at the top of the program. zero is that the normal for the “successful execution of the program”.

## What is Printf and Scanf ?

The printf() and scanf() functions area unit used for input and output in C language. each functions area unit inherent library functions, outlined in stdio.h (header file).

## What is Compiler ?

The language processor that reads the whole program written in application-oriented language as a full in one go and interprets it into identical program in machine language is named a Compiler. Example: C, C++, C#, Java. compilers/assemblers area unit themselves package, and reside where they were put in on the pc. that additionally implies that you just will have as many/few of every as you wish.

## How “Conditional Statements in C – HackerRank Solution”  program works?

• The #include is a preprocessor command that tells the compiler to include the contents of stdio.h (standard input and output) file in the program.
• The stdio.h file contains functions such as scanf() and printf() to take input and display output respectively.
• If you use the printf() function without writing #include <stdio.h>, the program will not compile.
• The execution of a C program starts from the main() function.
• printf() is a library function to send formatted output to the screen. In this program, printf() displays C Language Welcome To C!!
text on the screen.
• The return 0; statement is the “Exit status” of the program. In simple terms, the program ends with this statement.

The #include could be a preprocessor command that tells the compiler to incorporate the contents of stdio.h (standard input and output) enter the program.
The stdio.h file contains functions like scanf() and printf() to require input and show output severally.
If you utilize the printf() perform while not writing #include , the program won’t compile.
The execution of a program starts from the main() perform.
printf() could be a library perform to send formatted output to the screen. during this program, printf() displays hello, World! in C text on the screen.
The return 0; statement is the “Exit status” of the program. In straightforward terms, the program ends with this statement.

#### Hackerrank Answer Conditional Statements in C – HackerRank Solution

Conditional Statements in C – HackerRank Solution may be a sample program designed to acquaint users with most programming languages. Beginners ar introduced to the essential syntax of a programing language by learning the way to print out “Hello World” on the device screen. printf(“Hello World”); This line tells the compiler to show the message “Hello World” on the screen. This line is termed an announcement in C. each statement is supposed to perform some task.
