Question

Comment each C statement in C program and write output.

Certainly! Below is the transcription of the code snippet from the image: ```c main () { int m[5] = {1, 3, 5, 7, 9}; int x, y = 0; for (x = 0; x < 3; x++) { y = y + m[x]; } printf("%d", y); } ``` ### Explanation: This is a simple C program that calculates the sum of a subset of elements from an array and prints the result. 1. **Array Initialization**: The array `m` of length 5 is initialized with the values `{1, 3, 5, 7, 9}`. 2. **Variable Definition**: Two integer variables `x` and `y` are defined. Variable `y` is initialized to 0. 3. **For Loop**: - The loop iterates over the array elements from index 0 to 2. - For each iteration, the corresponding element of the array `m[x]` is added to `y`. 4. **Output**: Finally, the program prints the value of `y`. ### Purpose: The program computes the sum of the first three elements of the array `m` (i.e., 1, 3, and 5) and prints the result. The expected output is `9`.
