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
4 digits
Make sure that your program works for the numbers 0, 1, and
10. For the number 0, the output should be
1 digit

int num;
cout<<"enter the number ";
cin>>num;
if (num>=0 && num<=9)
cout<<"You have entered one digit";
else if (num>=10 && num<=99)
cout<<"You have entered two digits";
else if (num>=100 && num<=999)
cout<<"You have entered three digits";
else if (num>=1000 && num<=9999)
cout<<"You have entered four digits";
else if (num>=10000 && num<=99999)
cout<<"You have entered five digits";

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.
