Question

Write a complete C++ program that do following.

1) Read a positive integer from the user with proper prompt. Assume that this user is nice and he/she would not start the integer with digit 0.

2) Create a size 10 array as counters for digits 0 - 9.

3) Use a while loop for processing

a) Single out the current last digit using modular 10 technique

b) Increment the corresponding counter through the index derived in a).

4) At the end display the non-zero counters and its corresponding digit in ascending order, i.e. 0 to 9.

For example, if the user enter 1773233, the output should be All digits occurrences:

1: 1

2: 1

3: 3

7: 2

Answer 1

Note:

Please find the below C++ program and sample output.

Please revert back in case of any concerns.

Program:

int main()
{
long int number;
int digits;
cout<<"Enter Number: ";
cin >> number;
int counter[10] ={0,0,0,0,0,0,0,0,0,0};
while (number != 0) {
digits = number % 10;
counter[digits] = counter[digits] + 1;
number = number/10;
}
for (int i=0;i<10;i++) {
if (counter[i] !=0) {
cout<<i<<": "<<counter[i]<<endl;
}
}
return 0;
}

Output:

The user enter 1773233, 1: 1 2: 1 3: 3 7: 2 user enter 162217 0: 1 1: 1 2: 5 3: 1 6: 1 7: 2 8: 3 9: 1
