Using a sound level meter, the noise emanated from 10 Proton X50 at different frequency levels are measured and shown in Table-1. (a) (b) Write a program in C to write the data into a binary file named proton.txt. Write a program that reads the data from the file proton.txt and find the car that emanates the minimum noise at 100Hz. Also write a program that reads the data from the file proton.txt and find the cars whose noise level is less than 60 dB at 400 Hz. (c) Table-1 Car Noise Level (dB) Vehicle Number 50Hz 100Hz 200Hz 400Hz 800Hz AKU4444 52.4 55.7 63.1 60.3 63.5 BKT9876 51.5 46.3 49.6 50.3 48.4 CBU5971 56.3 61.2 60.3 59.7 58.1 CKD2813 57.9 58.6 63.2 65.3 64.9 DEL 8690 53.0 59.2 60.5 62.4 63.1 JAP7561 51.2 52.4 54.7 58.3 60.9 KUL9781 55.8 58.1 59.6 61.8 62.5 MMA1985 49.1 48.2 50.5 53.7 57.8 PPP8668 43.6 44.8 48.4 47.1 50.8 RAA6767 58.7 56.9 60.5 62.3 58.1
