#include <stdio.h>

int main() {
    printf("Hola, mundo!\n");
    return 0;
}

Explanation:

#include <stdio.h>: This line includes the standard input-output library in the program, which contains functions like printf and scanf used for input and output operations.
int main() {: This line signifies the beginning of the main function, the entry point of every C program. The int before main indicates that the function returns an integer value.
printf("Hola, mundo!\n");: This line uses the printf function to print the string "Hola, mundo!" to the console. The \n is an escape sequence representing a newline character, which moves the cursor to the next line.
return 0;: This line indicates the end of the main function and returns an integer value (0 in this case) to the operating system. It is a convention to return 0 to signify that the program executed successfully.
}: This closing brace marks the end of the main function and the end of the C program.
