-> C

Understood! Here are explanations for each step in a C program:

1. Include Libraries: c #include <stdio.h> Explanation: Includes the standard input-output header file, allowing the use of functions like printf() and scanf().

2. Main Function: c int main() { // Code return 0; } Explanation: Entry point of the program where execution begins. 'int' indicates the return type of the function. 'return 0;' signifies a successful execution.

3. Variable Declaration: c int a, b, sum; Explanation: Declares variables 'a', 'b', and 'sum' as integers.

4. Input: c printf("Enter two numbers: "); scanf("%d %d", &a, &b); Explanation: Prompts the user to input two numbers. 'scanf()' reads and stores the input values into variables 'a' and 'b'.

5. Calculation: c sum = a + b; Explanation: Adds the values stored in variables 'a' and 'b', and assigns the result to 'sum'.

6. Output: c printf("Sum = %d\n", sum); Explanation: Displays the value of 'sum' using printf().

7. Return Statement: c return 0; Explanation: Marks the end of the 'main()' function and returns '0' to indicate successful program execution to the operating system.
