c programming

it works for 1 but fails for second

any idea how to fix it

Write an expression that will cause the following code to print "Equal" if the value of sensor Reading is "close enough to targetValue. Otherwise, print "Not equal". Ex: If targetValue is 0.3333 and sensor Reading is (1.0/3.0), output is: Equal 1 #include 2 #include 3 4 int main(void) { 5 double targetValue; 6 double sensorReading: 7 8 scanf("%f", &targetValue); 9 scanf("%1f", &sensorReading); 10 11 if (abs (targetValue-sensor Reading)
