int main int num1 = 0; int num2 = 0; scanfdd &num1 &num2; int sum = 0; sum = num1 + num2; printf和为dn sum; return 0;

The given code reads two integers from the user using scanf, adds them together, and then prints the sum to the console using printf. The sum is stored in the variable sum.

Here's how the code works:

1. Two integer variables num1 and num2 are declared and initialized to 0.
2. The user is prompted to enter two integers.
3. The scanf function reads the two integers provided by the user and stores them in num1 and num2.
4. Another integer variable sum is declared and initialized to 0.
5. The sum variable is assigned the sum of num1 and num2.
6. The printf function is used to print the sum to the console.
7. The program ends and returns 0, indicating successful execution
