Answer:
The output of this question is 21. As show in the image
The explanation is given in below
Explanation:
Let first write the question
C=1
sum = 0
while(C<10):
C=C+3
sum=sum + C
print(sum)
Now Focus on
while(C<10):
C=C+3
sum=sum + C
The value of C is initially 1
C=1+3
Sum= 0+4
In second loop the value of C will become 4
c=4+3
sum=4+7
In third loop the value of C will be 7
c=7+3
sum=11+10
so the answer is 11+10=21
Answer:
Option b outFile.open("outputData.out");
Explanation:
In C++, there are several classes given to handle output and input of characters to or from files. They are:
- ofstream that write on files
- ifstream that read from files
We can use an object of ofstream to hold the contents that we wish to output to an external file. The general syntax is as follows:
ofstream_obj.open(file_name)
This will create a file with a specific file name and it possesses all the contents from the obstream_obj.
