Your task is to print a message saying in which of following intervals the number belongs: [0,25] (25,50], (50,75], (75,100]. If the input is less than zero or greather than 100, the program must print the message “Fora de intervalo” that means "Out of Interval". Examples: [0,25] indicates numbers between 0 and 25.0000, including both. (25,50] indicates numbers greather than 25 (25.00001) up to 50.0000000. Input The input file contains a floating-point number. Output The output must be a message like following example. Sample Input Sample Output 25.01 Intervalo (25,50] 25.00 Intervalo [0,25] 100.00 Intervalo (75,100] -25.02 Fora de intervalo Solution: #include<stdio.h> int main() {      double n;...
