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 ::270.546million.
USA's population ::274.213 million.
Mexico's population ::273.278million.
USA's population ::273.802 million.
Answer:
"Option b and Option d" is the correct option for this question.
Explanation:
In the database, datatype belongs to the information storage medium, which can hold a specific type of value. There are several data types, which is used in database like integer, character, series, floating-point and array numbers, and the rules, that give levels of security to information are known as a security constraints. It may be either developed as rules on integrity, mathematical formalism rules or schematic rules, and other choices were wrong which can be described as follows:
- In option a, The asserts, which is in any exchange in a database, should only modify the information, that is effected in acceptable ways is called consistency, that's why it is wrong.
- In option c, The validity and accuracy of the data in the database can not be ensured, that's why it is wrong.
I would say A:keywords
Hope this helps
I’m sorry if this is wrong
Have a great day/night
Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
<em>else:</em>
<em> print("Positive integer only")</em>
Here are some of the computers used in the first generation of computers:
ENIAC
EDVAC
UNIVAC
IBM-701
IBM-650
These are some of the first computers ever that led to today's computers.
