Why is this not running the right way? Someone explain it to me in C programming please? thank you

CHALLENGE ACTIVITY 3.13.1: Floating-point comparison: Print Equal or Not equal. Write an expression that will cause the following code to print "Equal" if the value of sensorReading is 'close enough' to targetValue. Otherwise, print "Not equal". Hint: Use epsilon value 0.0001. Ex: If targetValue is 0.3333 and sensorReading is (1.0/3.0), output is: Equal Code writing challenge activity demo Testing with targetValue =0.3333, sensorReading =1.0/3.0 Your output X Testing with targetValue =0.3333, sensorReading =2.0/3.0 Output differs. See highlights below. Your output Expected output Testing with targetValue =0.6, sensorReading =0.1+0.2+0.3 Your output
