Question

Write a program to read an integer number and find its number of digits (for example, 3459 has 4 digits and 125860 has 6 digits).

The program should be designed in a way that the user could test as many numbers as desired without leaving the program. Use only long integer ( int or long int ) data type in this problem; however make sure that the program rejects any input outside the long integer data range(about -2,000,000,000 to +2,000,000,000).

The outputs of the program should be written to an output file having a format exactly like the following table.



VALUE ENTERED NUMBER OF DIGITS
1241 4
19 2
5684900 7
0 1
1267678901 10
-153 3
62000 5




Test the program for at least seven integer values between ± 2,000,000,000 and a number outside the long int data range . Remember to submit a copy of the program file and a copy of the output file.

Explanation / Answer

int num_digits; if (myNumber < 0) myNumber = -myNumber; while(myNumber > 0) { num_digits++; myNumber/=10; }
