Question

Q1: Write an algorithm and sketch the flowchart to read 20 numbers for x and finding the number of times that the number 100 is repeated between these numbers. (12 marks) Q2: What is the difference between prefix decrementer (- - i) and postfix decrementer (i - -) explain using examples. Q3: C++ includes a very special operator called the ternary operator. Explain with example how this operator used? Q4: Write C++ Program which output this result ******50 *****500 ****5000 Q5: Write C++ program to print the number (13579) in the reverse order.

Answer 1

2.1. Algo Dead count=0 for = to i,2o Read if (ac equals loo) count++ end for print count

Flowchart Start -Count-o 9 i=1 No i<=20 ? Print Count Itt Yes Read x End Yes Count tt (x==100

#include<iostream>
using namespace std;

int main()
{
        int count=0;

        for(int i=1;i<=20;i++)
        { 
          int x;
          cin>>x;
          if(x==100)
          count++;
        }

        cout<<count;
}
