Answer:

A computer program is not reasonably correct if it has no error messages during translation.

 

Explanation:

First, we need to understand what the statement means, and we also need to identify the keywords.

The statement means that, when a program does not show up error during translation; this does not mean that the program is correct

Having said that:

We can replace some keywords as follows:

absence of error messages := no error messages

Vsevolod [243]

Answer:

The correct option is B

B. How many states have a higher percentage of female computer science majors than male computer science majors attending college in that state?

Explanation:

A.We can not analyze that students majoring in computer science tend to have higher grade point averages than students majoring in other subjects because we are only given data sets about computer science not about other majoring subject students

B. Because data set contains attributes of gender and state so we can easily analyze that how many states have a higher percentage of female computer science majors than male computer science majors attending college in that state.

C.We can not analyze that what percent of students attending college in a certain state are majoring in computer science because data sets doesn't contain any information about students other computer science students.

D. We can not analyze that which college has the highest number of students majoring in computer science because data sets doesn't contain attribute of college name.

Write a program that has a while loop to print out the first five multiples of 15, 43, and 273 between the numbers of 3168 and 3
Reika [66]

Answer:

#include <iostream>

using namespace std;

void printmultiples(int n) //function to print first five multiples between 3168 and 376020

{

   int a =3168,c=1;

   cout<<"First five multiples of "<<n<<" are : ";

   while(a%n!=0 && a<=376020) //finding first mutiple of n after 3168.

   {

       a++;

   }

   while(c<6)//printing multiples.

   {

       cout<<a<<" ";

       a+=n;

       c++;

   }

   cout<<endl;

}

int main() {

   int t,n;

   cin>>t;//How many times you want to check.

   while(t--)

   {

       cin>>n;

       printmultiples(n);//function call..

   }

return 0;

}

Input:-

3

15

43

273

Output:-

First five multiples of 15 are : 3180 3195 3210 3225 3240  

First five multiples of 43 are : 3182 3225 3268 3311 3354  

First five multiples of 273 are : 3276 3549 3822 4095 4368

Explanation:

I have used a function to find the first five multiples of the of the numbers.The program can find the first five multiples of any integer between 3168 and 376020.In the function I have used while loop.First while loop is to find the first multiple of the integer n passed as an argument in the function.Then the next loop prints the first five multiples by just adding n to the first multiple.

In the main function t is for the number of times you want to print the multiples.In our case it is 3 Then input the integers whose multiples you want to find.
