// Write an program to read two scores of a student. Calculate and print the semester average. The program must accept only valid scores (a score must fit in the range [0.10]). Each score must be validated separately.

// The program must print a message "novo calculo (1-sim 2-nao)" that means "new calculate (1-yes 2-no)". After, the input will be (1 or 2). 1 means a new calculation, 2 means that the execution must be finished.

// Input
// The input file contains several positive or negative floating-point (double) values​. After the input of 2 valid scores, an integer number X will be read. Your program must stop when X = 2.
