Welcome!
Today we are going to solve another question of HackerRank.So,
let’s do it.
#Below the following text/question is taken straight from HackerRank :-
Objective
The
fundamental data types in c are int, float and char. Today, we're discussing
int and float data types.
The printf() function prints the given statement to the console. The syntax
is printf("format
string",argument_list);. In the
function, if we are using an integer, character, string or float as argument,
then in the format string we have to write %d (integer), %c (character), %s (string), %f (float) respectively.
The scanf() function reads the input data from the console. The syntax
is scanf("format string",argument_list);. For ex: The scanf("%d",&number) statement reads integer number
from the console and stores the given value in variable number .
To input
two integers separated by a space on a single line, the command is scanf("%d %d", &n,
&m), where n and m are
the two integers.
Task
Your task is to take two numbers of
int data type, two numbers of float data type as input and output their sum:
1. Declare 4 variables: two of
type int and two of type float.
2. Read 2 lines of input from
stdin (according to the sequence given in the 'Input Format' section below) and
initialize your 4 variables.
3. Use the + and - operator
to perform the following operations:
o
Print the
sum and difference of two int variable on a new line.
o
Print the
sum and difference of two float variable rounded to one decimal place on a new
line.
Input
Format
The first line contains two integers.
The second line contains two floating point numbers.
Constraints
·
1< integer
variables<10^4
·
1<float
variables<10^4
Output
Format
Print the
sum and difference of both integers separated by a space on the first line, and
the sum and difference of both float (scaled to 1 decimal place)
separated by a space on the second line.
Sample
Input
10 4
4.0
2.0
Sample
Output
14 6
6.0
2.0
Explanation
When we
sum the integers 10 and 4 , we get the integer 14 . When we
subtract the second number 4 from the first number 10, we get 6 as
their difference.
When we sum the floating-point numbers 4.0 and 2.0 , we get 6.0 .
When we subtract the second number 2.0 from the first number 4.0 ,
we get 2.0 as their difference.
Solution
#include <string.h>
#include <math.h>
#include <stdlib.h>
int main()
{
int num1, num2;
float num3, num4;
scanf("%d %d", &num1, &num2);
printf("%d %d\n", num1+num2, num1-num2);
scanf("%f %f", &num3, &num4);
printf("%.1f %.1f", num3+num4, num3-num4);
return 0;
}
Above I have
provided image and textual form of the solution. I hope that you won’t just
copy paste try to understand the code.
Well, that’s it here is the solution and if you have any difficulty in understanding any line of the code, feel free to ask me in the comment section. 😃
