convert c code to c++

Sure! Here is a response:

C Code:

#include <stdio.h>

int main() {
    int number1, number2, sum;

    printf("Enter first number: ");
    scanf("%d", &number1);

    printf("Enter second number: ");
    scanf("%d", &number2);

    sum = number1 + number2;
    printf("Sum is: %d", sum);

    return 0;
}

C++ Code:

#include <iostream>

int main() {
    int number1, number2, sum;

    std::cout << "Enter first number: ";
    std::cin >> number1;

    std::cout << "Enter second number: ";
    std::cin >> number2;

    sum = number1 + number2;
    std::cout << "Sum is: " << sum;

    return 0;
}

Explanation: 1. Replaced #include <stdio.h> with #include <iostream> to enable C++ input/output operations. 2. Replaced printf and scanf with std::cout and std::cin respectively for C++ style input/output. 3. No changes required for variable declarations and arithmetic operations. 4. Modified printf statement to std::cout and scanf to std::cin for taking input and output in C++.
