Answer:
// here is code in c++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main() {
// variable
int num;
int tot_sum=0;
cout<<"enter a number: ";
// read the value of n
cin>>num;
// check the multiple of 2 or 5 from 1 to n
for(int x=1;x<=num;x++)
{
// if multiple of 2 or 5 then add them
if(x%2==0 ||x%5==0)
{
tot_sum=tot_sum+x;
}
}
// print the sum
cout<<"sum of multiple of 2 or 5 is:"<<tot_sum<<endl;
return 0;
}
Explanation:
Read the number "n" from user.Check every number from 1 to n, if it is a multiple of 2 or 5 then add them to "tot_sum".When the for loop end, "tot_sum" will have sum of all the number which are either multiple of 2 or 5.Print the sum.
Output:
enter a number:11
sum of multiple of 2 or 5 is:35

Answer:
# create the file
filename = "Testfile.txt"
# for writing, we create the output file:
outPutfile = open(filename, "w")
# Writing numbers from 1-100
for item in range(1,101):
outPutfile.write((str)(item))
outPutfile.close()
# printing the contents to verify it worked correctly
infile = open(filename, "r") #note the "r" indicates the mode
fileContents = infile.read()
infile.close()
print(fileContents)
Explanation:
- Define the working file fileName = TestFile
- Create the output file for writting outPutfile = open(filename, "w")
- Use a for loop to write numbers from 1-100 to the file outPutfile.write((str)(item))
- Close the file outPutfile.close()
- You may open the file read its content and print the contents to verify it worked correctly
Answer:
"double result=6.759;" is the correct answer for the above question.
Explanation:
- In c-programming language, the double is a data type which stores the decimal value up to 6 decimal point.
- This data type takes 8 bytes space in memory when it is used in the c-programming language.
- When the user wants to declare the double data type, then he should need to declare by the help of the following syntax-- double variable_name_or _identifier_name;
- When the user wants to declare the double data type and initialize the value on its then he can do this with the help of the following syntax--double variable_name_or _identifier_name= value_which_needs_to_store;
- The above question asked the one-line statement which declares the result variable of double data type and initializes the "6.759" value on its then he can do this by the help of "double result=6.759;" statement which is described above. Hence the answer is "double result=6.759;".
