Problem Name:
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 4 variables: two of type int and two of type float.
- Read 2 lines of input from stdin (according to the sequence given in the ‘Input Format’ section below) and initialize your 4 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 <= 10⁴
1 <= float variables <= 10⁴
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
and , we get the integer . When we subtract the second number from the first number , we get as their difference.
When we sum the floating-point numbers 4.0 and 2.0, we get 60. When we subtract the second number 2.0 from the first number 4.0, we get 2.0 as their difference.
