Question

5. Write a program that does to perform the following using: Reads a number num that is in the range from 0 to 999999999 and a digit n that is in the range from 0 to 9 from the user. Write while loop to force user to enter appropriate values. . Finds how many times the digit n occurs in the number num. Prints the output as shown. Eİ CAWindowsisystem32cmdexe Enter number ( to 999999999): 3545592 the digit S appears 3 times in the number 3545592 ress any key to continue ..- the digit i apesrar s tfnes in the number 3545592 Hint: use / and % operators to get each digit from the number.

Answer 1

#include <iostream>

using namespace std;

int main()
{
long int num;
int n;
cout<<"Enter Number(0 to 999999999)";
cin>>num;
cout<<"Enter Value of n(0 to 9)";
cin>>n;
cout<<"\n";
while(num>999999999 && num>0)
{

cout<<"Enter the values of num within range";
cout<<"Enter Number(0 to 999999999)";
cin>>num;

}
while( n>9 &&n>0)
{

cout<<"Enter the values of n within range";
cout<<"Enter Value of n(0 to 9)";
cin>>n;
}

int count=0,temp;
long int num1=num;
while(num1)
{
temp = num1%10;
num1 = num1/10;
if(temp==n)
count++;
}
cout<<"the digit "<<n<<" appears "<<count<<" number of times in the number "<<num;
return 0;
}

OUTPUT

Enter Number(0 to 999999999)555559089 Enter Value of n(0 to 9)5 the digit 5 appears 5 number of times in the number 555559089 Exit code: 0(normal program termination)
