#include <stdio.h> int main() { int a = 5, b = 10; int sum = a + b; printf("Sum: %d", sum); return 0; }
1) This code calculates the sum of two integers (5 and 10) and prints the result.

2) Hint: Notice how variables are declared and initialized on the same line.
Hint: The printf function uses %d as a placeholder for integer values.
