// filereader.c // CS 351 // // Demonstrate reading text file character by character #include // I/O library int main() { FILE* fp; // file pointer char ch; // store characters read from file fp = fopen("input.txt", "r"); // open file for reading // Visual Studio users: you may need to use fopen_s() as shown below or disable the warning on fopen() //fopen_s(&fp, "input.txt", "r"); // open file for reading if( fp == NULL ) { // if open failed printf("Error: can't find data file. Abort program now. "); return 1; // terminate now } // read from file while ( (ch = fgetc(fp)) != EOF ) { // read one char, go into the loop if not EOF // 1. process this char printf("%c", ch); // just print on screen } // end of reading file while loop fclose(fp); // close file return 0; } // end main Change the program so that it outputs the percentage of uppercase characters (A-Z), the percentage of lowercase characters (a-z), and the percentage of digits (0-9) in the text file. Note that these percentages will NOT add up to 100! For example, in the highlighted purpose sentence above, there are 83 characters: 3 upper case, 61 lowercase, 1 digit, plus spaces and punctuation. Your program should just print a message like this: There are 83 characters, with 3.61% upper case, 73.49% lower case and 1.20% digits.
