Question

Lab 2: (one task for Program 5): Declare an array of C-strings to hold course names, and read in course names from an input file. Then do the output to show each course name that was read in. See Chapter 8 section on "C-Strings", and the section "Arrays of Strings and C-strings", which gives an example related to this lab. Declare the array for course names as a 2-D char array: char courseNames[10] [ 50]; -each row will be a C-string, and you can use it by writing courseNames[i] were one-dimensional. Use infile.get(courseNames [ i], 50); will put in the null character after the input data for you. Note: The get function reads characters into the array across an a newline character. It does not remove the newline character from the input stream, so in order to read the next line, your program must do that. The textbook suggests declaring char discard; (allows for 10 courses and up to 49 characters in a course name) as if the array for reading C-string data row-by-row; the get function input file line, until it encounters and using infile.get(discard); to read the newline character into the variable discard (thereby removing it from the input stream). fu at op to Plase pogiam itopfo oR OUTPUT fh.No SCRECN INPUT Thauks
