Answer:
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
double mexico = 114;
double usa = 312;
double mexicoRate = .0101;
double usaRate = .0015;
// calculate population after every year until mexico population exceed the usa populationn
while (usa>mexico)
{
// print the population
cout<<"Mexico's population ::"<<mexico<<" million."<<endl;
cout<<"USA's population ::"<<usa<<" million."<<endl;
// update the population
mexico+=mexico*mexicoRate;
usa-=usa*usaRate;
}
return 0;
}
Explanation:
Declare and initialize mexico and usa with their initial population.Also declare and initial their increase and decrease rate.Find the population of both the country each year until mexico population exceeds the usa population.
Output:
Mexico's population ::114 million.
USA's population ::312 million.
Mexico's population ::115.151 million.
USA's population ::311.532 million.

Mexico's population ::273.278million.
USA's population ::273.802 million.
Answer: b) False
Explanation:
Alternative method that is used for information system consisting of prototyping, outsourcing, end-user development mechanism, system life cycle etc for building a system.
- These process consist of focusing on user requirement, using high level programming languages, development of prototype,creation of package, database etc instead of cross-sectional phase,selection decisions,top management option etc.
- Therefore, the correct option is option(b) as the statement is false.
