Write a program that will count the number of digits in an
input integer up to value MAX_VALUE (2147483647). Thus, for
an input of 5837 the output should be

Answer / sandeep mannarakkal
I have another suggestion for the above,
int iInputNumber;// This number is used for collecting input from user.
int nCount = 1;
while ( iInputNumber /10 )
{
iInputNumber = iInputNumber/10;
nCount ++;
}
cout << nCount << endl; // nCount will have the count of digits.
