## For Loop in C HackerRank Solution Explain Video:

For Loop in C HackerRank Solution , We Discuss About That.

### Problem :

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

### Objective :

In this challenge, you will learn the usage of the for loop, which is a programming language statement which allows code to be executed until a terminal condition is met. They can even repeat forever if the terminal condition is never met. The syntax for the for loop is: for ( <expression_1> ; <expression_2> ; <expression_3> ) <statement>

• expression_1 is used for initializing variables which are generally used for controlling the terminating flag for the loop.
• expression_2 is used to check for the terminating condition. If this evaluates to false, then the loop is terminated.
• expression_3 is generally used to update the flags/variables

A sample loop will be for(int i = 0; i < 10; i++) { … }

For each integer n in the interval [a,b] (given as input) :

• If 1<= n , then print the English representation of it in lowercase. That is “one” for 1, “two” for 2, and so on.
• Else if n > 9and it is an even number, then print “even”.
• Else if n < 9and it is an odd number, then print “odd”.

## Input Format:

The first line contains an integer, a.

The second line contains an integer, b.

8

11

eight

nine

even

odd

## Solution Solution :

int main()
{
int a, b;
scanf(“%d\n%d”, &a, &b);

char str[][100]={“zero”,”one”,”two”,”three”,”four”,”five”,”six”,”seven”,”eight”,”nine”};
for(int i=a;i<=b;i++){
if(i<=9){
printf(“%s\n”,str[i]);
}
else
{
if(i%2==0){
printf(“even\n”);
}
else
printf(“odd\n”);
}
}
return 0;
}

## 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 “For Loop 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 For Loop in C HackerRank Solution

For Loop 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.
