Answer (2)
The code provided is a simple C++ program that performs input and output operations while calculating sums and mixed arithmetic expressions using four integer variables. It utilizes the standard input/output library and demonstrates basic arithmetic in C++. The program is structured to read and output numbers while also performing specific calculations on them.
;
This code is written in C++, a popular programming language used for system/software development and competitive programming.
Let's break down what this program does step-by-step:
Include and Setup:
The #include line allows the program to use input and output functionalities, specifically cin and cout, for reading from and writing to the screen.
using namespace std; allows the program to use all the standard library functions and objects without repeatedly specifying the std:: prefix.
typedef long long ll; defines ll as an alias for the long long data type, which is used for large integer values.
Main Function:
The main() function is where the program execution begins.
ll x, y, z, t; declares four variables (x, y, z, t) of type long long.
Input and Output:
cin >> x >> y >> z >> t; receives four integer inputs from the user, storing them in the variables x, y, z, and t.
The line cout << x << ", " << y << ", " << z << ", " << t << endl; prints the values of the four variables with commas in between, followed by a newline.
Calculations:
cout << x + y + z + t << endl; calculates the sum of the four variables and prints the result.
cout << x - y + z * t << endl; performs a mixed arithmetic operation where x is subtracted by y, and then z multiplied by t is added. The result of this expression is printed.
Return Statement:
return 0; indicates that the program executed successfully.
To summarize, this program reads four integer values, outputs them, sums them up, and performs a specific arithmetic operation on these values before displaying the results. It demonstrates basic input/output operations and arithmetic operations in C++.
