Question

With the use of nested if, develop a preliminary visa interview application using C++. The application should be able to test if an applicant is qualified to apply for a visa.

i. If you are not born Nigerian, it will instruct you to apply from your own country.
ii. If you are unemployed and not a student, your application will be rejected.
iii. It will ask for your purpose of traveling; if not visiting or studying, it will deny the visa.
iv. If you are married or your age is from 18 to 25, the visa will be granted; otherwise, it will be denied.

Answer 1

In C++, you can use nested if statements to develop a preliminary visa interview application. The program will evaluate different conditions such as nationality, employment status, purpose of travel, marital status, and age to determine whether the applicant is qualified for a visa.

Step-by-step explanation:

In C++, you can use nested if statements to develop a preliminary visa interview application. Here's an example code:

#include <iostream>
using namespace std;

int main() {
string nationality;
bool unemployed, student;
string purpose;
bool married;
int age;

cout << "Enter your nationality: ";
cin >> nationality;

if (nationality != "Nigerian") {
cout << "Apply from your own country." << endl;
return 0;
}

cout << "Are you unemployed? (1 for Yes, 0 for No): ";
cin >> unemployed;

if (unemployed && !student) {
cout << "Application rejected." << endl;
return 0;
}

cout << "Enter the purpose of your travel: ";
cin >> purpose;

if (purpose != "visiting" && purpose != "studying") {
cout << "Visa denied." << endl;
return 0;
}

cout << "Are you married? (1 for Yes, 0 for No): ";
cin >> married;

cout << "Enter your age: ";
cin >> age;

if (married || (age >= 18 && age <= 25)) {
cout << "Visa granted." << endl;
}
else {
cout << "Visa denied." << endl;
}

return 0;
}

By running this code, you can input the necessary information and the program will determine whether the applicant is qualified to apply for a visa based on the given conditions.
