Welcome! 

Today we are going to solve another question of HackerRank.So, let’s do it.

C programming

#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

Solution
#include <stdio.h>

#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. 😃
