# Sum and Difference of Two Numbers

# Sum and Difference of Two Numbers

**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 .

To input two integers separated by a space on a single line, the command is `scanf("%d %d", &n, &m)`

, where and 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**

- integer variables
- float variables

**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 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 and , we get . When we subtract the second number from the first number , we get as their difference.
