Thank you both.  I'm using Windows 10, and justr followed BlueHazzard's & stahta01's advice.  The compiler was detected and the program now attempts to compile.  However, it did not compile and here is the error message:
||=== Build file: "no target" in "no project" (compiler: unknown) ===|
||error: C:\Users\jfele\OneDrive\??\2.Learning\f. My own studies\Computing\C\25.c: Invalid argument|
||error: no input files|
||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|
I just walked through my code and did not find any errors.  Is it because it cannot include the two #include .h files?
Is this another easy fix?
Appreciate any help.  Here is my short program:
// Example program #1 from Chapter 15 of Absolute Beginner's Guide
// to C, 3rd Edition
// File Chapter15ex1.c
/* This program will ask users how many movies they've seen this
year, and then loop through asking the name of each movie and a
rating from 1 to 10.  It will remember their favourite movie and
their least favourite movie. */
#include <stdio.h>
#include <string.h>
main()
{
    int ctr, numMovies, rating, favRating, leastRating;
    char movieName[40], favorite[40], least[40];
    // Initialize the favRating to 0 so any movie with any rating of
    // 1 or higher will replace it and the leastRating to 10 so any
    // movie rated 9 or lower will replace it
    favRating = 0;
    leastRating = 10;
    // Find out how many movies the user has seen and can rate
    // The loop will continue until they enter a number more than 0
    do {
        printf("How many movies have you seen this year?");
        scanf(" %d", &numMovies);
        // If the user enters 0 or a negative number, the program
        // will remind them to enter a positive number and prompt
        // them again
        if (numMovies < 1)
        {
            printf("No movies!  How can you rank them?\nTry again!\n\n");
        }
    } while (numMovies < 1);
    for (ctr = 1; ctr <= numMovies; ctr++)
        {
                // Get the name of the movie and the user's rating
                printf("\nWhat was the name of the movie? ");
                printf("(1-word titles only!) ");
                scanf(" %s", movieName);
                printf("On a scale of 1 to 10, what would ");
                printf("you rate it? ");
                scanf(" %d", &rating);
                // Check whether it's their best-rated movie so far
                if (rating > favRating)
                {
                    strcpy(favorite, movieName);
                    favRating = rating;
                }
                // Check whether it's their worst-rated movie so far
                if (rating < leastRating)
                {
                    strcpy(least, movieName);
                    leastRating = rating;
                }
        }
    printf("\nYour favourite movie was %s.\n", favorite);
    printf("\nYour least favourite movie was %s.\n", least);
    return 0;
