Question
Chapter 5, Problem 45SA
Program Plan Intro
- 1Initialize integer value num.
- check using conditional loop if num value is greater than or equal to 0.
- If while condition is true, then it checks if condition as num %5 is 0. If yes, then increment and continue doing the loop else print value of num. Then decrement by 2 using num=num-2.
- Print the values.

Students have asked these similar questions
int sum = 0;
for (int i
0; i < 5; i++){
sum += i;
}
cout << sum;
#include<iostream>using namespace std;void main(){double pi = 0, denominator = 1;int counter = 999999;for (int x = 0; x < counter; x++){if (x % 2 != 0){pi = pi - (1 / denominator);}else{pi = pi + (1 / denominator);}denominator = denominator + 2;}pi = pi * 4;cout << " So the computed value of a PI is = " << pi << endl;cout << " ";//return 0;system("pause");}
Note:
This a program called ComputePI to compute the value of π
Tutor just have to Modify This program to use nested-if (if ... else if ... else if ... else) instead.
Explain by applying a double line comment
Void Do1 (int: &, a. int &b)
{
a = 5;
a = a + b;
b = a + 2;
}
Int main()
{
Int x = 10;
Do1 (x,x);
Cout << x << endl;
}
