Write a C++ program that inputs the world's population at the end of last year. Assume population is growing at a rate of 1.12%.

Output the year (starting with this year) and the population until the population is greater than 10billion.

Test data: 6.83 billion. (leave like this rather than 6800000000).

Name as a comment and printed to output. Output as a comment at the bottom of the code

#include <iostream>

using namespace std;

int main()
{
double p,rate=1.12,total=0;
int y;
  
cout << "Enter worlds population in billion" << endl;
cin>>p;
cout << "Enter the year" << endl;
cin>>y;
while(total<10) // to check total population is less than 10 billion.
{
total=p+((1.12*p)/100);
p=total;
cout<<"year:"<<++y<< endl;
cout<<"Total population"<< p<<"billion"<< endl;
}

return 0;
}

Ex: If the input is: 7 15 3 the output is: largest: 15 smallest: 3 Your program must define and call the following two functions. The LargestNumber function should return the largest number of the three input values. The SmallestNumber function should return the smallest number of the three input values. int...

In c++ language, write a void function GetYear that prompts for and inputs the year the operator was born (type int) from standard input. The function returns the user’s birth year through the parameter list (use pass by reference) unless the user enters an invalid year, in which case a BadYear exception is thrown. To test for a bad year, think about the range of acceptable years. It must be 4 digits (i.e. 1982) and it cannot be greater than...
