## Algorithm

Problem Name: Input and Output

In this HackerRank Functions in C++ programming problem solution,

Objective
In this challenge, we practice reading input from stdin and printing output to stdout.

In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout. For example, let's say we declare the following variables:

string s;
int n;


and we want to use cin to read the input "High 5" from stdin. We can do this with the following code:

cin >> s >> n;


This reads the first word ("High") from stdin and saves it as string s, then reads the second word ("5") from stdin and saves it as integer n . If we want to print these values to stdout, separated by a space, we write the following code:

cout << s << " " << n << endl;


This code prints the contents of string s, a single space (" "), then the integer n. We end our line of output with a newline using endl. This results in the following output:

High 5


Read 3 umbers from stdin and print their sum to stdout.

Input Format

One line that contains 3 pace-separated integers: a,b and c.

Constraints

• 1 <= a,b,c <= 1000

Output Format

Print the sum of the three numbers on a single line.

Sample Input

1 2 7


Sample Output

10
