HackerRank Conditional Statements in C solution

HackerRank Conditional Statements in c problem solution – In this tutorial, we are going to solve HackerRank conditional statements in the c problem or write a solution program. In this problem, we need to read the positive integer value and then we need to check if the value is greater than print the text “Greater than 9” Else we need to print the English word that corresponds to that value in lowercase like if value 1 then print the one in lowercase.

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:

Task

Given a positive integer denoting n, do the following:

• If 1 <= n <= 9, 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, n.

Constraints

• 1 <= n <= 10⁹

Output Format

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

#include<stdio.h>
#include<string.h>
int main()
{
 int n;
 scanf("%d",&n);
  char *a[]={"zero","one","two","three","four","five","six","seven","eight","nine"};
  if(n<=9)
  {
     printf("%s",a[n]);
  }

 else
 {
     printf("Greater than 9");
 }
 return 0;
}

#include<stdio.h>
#include<string.h>
int main()
{
 int n;
 scanf("%d",&n);
  char *a[]={"zero","one","two","three","four","five","six","seven","eight","nine"};
  if(n<=9)
  {
     printf("%s",a[n]);
  }

 else
 {
     printf("Greater than 9");
 }
 return 0;
}

Explanation

In the above-given program first, we included the two header files stdio.h and string.h, after that we defined the main() function. inside the main function, we first defined the integer variable n and then using the scanf() function we read the user input value and stored it in the variable n.

after that, we defined an array named a with predefined values like zero, one, two, three, four, five, six, seven, eight, and nine. we used these values to get the corresponding English words of value from 0 to 9.

After that using the if condition we checked if the value was less than or equal to 9 then using the printf() function we printed the corresponding English word from the array. else we printed the “Greater than 9” text on the output screen.
