DCP 5101 PROGRAM DESIGN LAB 11 QUESTION 2 Write a complete C program that creates a new file called audio.txt for both writing and reading. The program prompts user to enter a series of inputs to calculate the audio size. User inputs and audio size are then written into file audio.txt. In main(): • Open a new file called audio.txt for writing and reading. If the file can't be opened, display error message "File could not be opened. Program aborted." And quit the program. Using a do-while loop: o Prompt user to enter audio channel (either 1 for mono or 2 for stereo), sampling rate, time, and bit depth. o Calculate audio size. • Formula: audio channel x sampling rate x time x (bit depth / 8) Write audio channel, sampling rate, time, bit depth and audio size into file audio.txt. o Prompt the user whether to continue adding another audio record. Repeat the above as long as user chooses to continue. From the beginning of file audio.txt, read and display all data from each audio record until the end of file. Close file audio.txt before program ends. SAMPLE OUTPUT CALCULATE AUDIO DATA SIZE Enter channel - [1] Mono [2] Stereo Enter sampling rate (Hz) Enter time (seconds) : 2 : 44100 : 30 : 16 Enter audio bit depth (bits) Add another record (y/n)? y Enter channel - [1] Mono [2] Stereo Enter sampling rate (Hz) Enter time (seconds) : 1 : 42500 : 25 Enter audio bit depth (bits) : 8 Add another record (y/n)? n Channel Sampling Rate Time Bit Depth Audio Size 44100.00 30 16 5292000.00 42500.00 25 8. 1062500.00
