Sum and Difference of Two Numbers HackerRank Solution
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:
-
Declare variables: two of type int and two of type float.
-
Read lines of input from stdin (according to the sequence given in the 'Input Format' section below) and initialize your variables.
-
Use the and operator to perform the following operations:
-
Print the sum and difference of two int variable on a new line.
-
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 <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
int main()
{
int a,b;
float c,d;
scanf("%d %d",&a,&b);
scanf("%f %f",&c ,&d);
int int_sum = a+b;
int int_diff = a-b;
float float_sum = c+d;
float float_diff = c-d;
printf("%d %d\n",int_sum,int_diff);
printf("%0.1f %0.1f", float_sum,float_diff);
return 0;
}
Steps Used in solving the problem -
-
Step 1: First, we included the required header files.
-
Step 2: Then, we created the main function and declared four variables.
-
Step 3: Then, we used two ‘scanf’ functions to read two integer inputs and two float inputs and stored them in declared variables.
-
Step 4: After this, we declared four variables to calculate and store the sum and difference of the two integers and the sum and difference of the two floats.
-
Step 5: Finally, we used printf to display the integer sum, integer difference, float sum, and float difference.
-
Note: The %d format specifier is used for integers, and the %f format specifier is used for floats.
