Question

Write a C program that will open the file myfile.txt
Verify that the file opened properly.

If the file did not open properly, display an error message and drop to the bottom of the program and exit.

If the file did open properly use a while loop to input all the text in the file, displaying each line as you input it. You can detect the end of the file using feof (file end of file). While you output three lines of text in program L14b, this program should correctly handle any number of lines including zero.

Explanation / Answer

#include #include int main() { char c; FILE *fp; fp = fopen("myfile.txt", "r"); // fp = fopen("myfile.txt", "r"); if(fp == 0) { fprintf(stderr, "Error opening myfile.txt. "); exit(1); } while ((c = fgetc(fp)) != EOF){ printf("%c",c); } fclose(fp); return 0; }
