Hi, I have a proble with my C++ program. The program should display the leading zeros but if I put 005, it only displays the reverse number 5 not 500. It will appreciated the solution. Thanks

This is the code:

#include

using std::cout;

using std::cin; //Allows the program to perform input and output

using std::endl;

/ecessary to convert character 'buffer' to integer 'num' with 'atoi'

#include

//function templates

int reverseNum(int);

int main()

{

//print my name and this assignment's title

cout

cout

cout

cout

cout

cout

//Program starts here:

//variables to store the input in the buffer and integers necessary to store the number from the user

//and display leading zeros if the user puts a digit with zeros

char buf[100];

int num, num1, len, temp, len1, ret;

while (true)

{

//prompt user for input

//the user puts a series of numbers less than 6 digits to do the reverse

//and they are stored in the buffer, to later convert it to integer and sotre the numbers

//in the variable called 'num'

cout

cin >> buf; num = atoi(buf);

//calculate length

len = 0;

while (buf[len] != '\0') //determines where in the 'buffer' variable the null character determinate

len++; //the end of C-style strings and calculate the length of the digits gathered from the user

if (len 6) //if length is

{

cout

continue; //if the length of input is more than 6 digits, the program displays

} //"Length of input should be 1 to 6 digits" and the program continues

//quit program if user entered a q

if (buf[0] == 'q' || buf[0] == 'Q')

break;

cout

ret = reverseNum(num); //ret gets the return type from 'reverseNum' function

temp = ret; //the temp variable gets the information stored in the 'ret variable'

len1 = 0; //'len1' variable stores 0 to display correctly the leading zeros

//with the loop from below

while (temp > 0) //find the length of the reversed number

{

temp = temp / 10; //formula necessary to display the leading zeros if the user puts

len1++; //a series of digits with leading zeros or has zero on the last character

}

//the program display the reversed number with leading zeros

cout

for (int i = 0; i

cout

//the last character

//display the reverse number after the leading zeros are displayed in the same line

//to show the leading zeros, otherwise it will display only the leading zeros

cout

}

}

//function integer 'reverseNum' necessary to do the reverse of the function

//and necessary to display the zeros of the user entered numbers that are

//leading with zeros

int reverseNum(int number)

{

int reversedNum = 0;

int reminder;

int zeros = 0;

bool firsttime = true;

while (number > 0)

{

reminder = number % 10;

//If reminder is 0 and the first non zero number is not yet encountered

if (reminder == 0 && firsttime)

{

zeros++;

}

//If first non zero digit is encounreted, zeros encountered later shouldn't be counted

else

{

firsttime = false;

}

reversedNum = reversedNum * 10 + reminder; //formula to display the reverse number

number /= 10; //the number gathered from the user is

//mutiplied by 10 and added with the reminder.

} //later the 'number' is divided by ten and added

//everything to 'reversedNum'

return reversedNum; //the 'reversedNum' is returned to returned to the

//main function with the calculations properly calculated

//and stored

}
