python
Sure, I can provide explanations for each step in C++ and Python.
C++:
#include <iostream>
int main() {
// Declare variables
int num1, num2, sum;
// Input values from the user
std::cout << "Enter first number: ";
std::cin >> num1;
std::cout << "Enter second number: ";
std::cin >> num2;
// Calculate the sum
sum = num1 + num2;
// Display the result
std::cout << "Sum: " << sum << std::endl;
return 0;
}
Explanation:
1. Include the necessary header file (#include <iostream>
) for input and output operations.
2. Declare three integer variables: num1
, num2
, and sum
.
3. Prompt the user to enter the first number and store it in the variable num1
.
4. Prompt the user to enter the second number and store it in the variable num2
.
5. Calculate the sum of num1
and num2
and store it in the variable sum
.
6. Display the result using std::cout
.
7. Return 0 to indicate successful program execution.
Python:
# Input values from the user
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
# Calculate the sum
sum = num1 + num2
# Display the result
print("Sum:", sum)
Explanation:
1. Use the input
function to get user input for the first number, convert it to an integer using int()
, and store it in the variable num1
.
2. Repeat the process for the second number, storing it in the variable num2
.
3. Calculate the sum of num1
and num2
and store it in the variable sum
.
4. Use the print
function to display the result.
