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.

emmasim [6.3K]

Answer:

create the integer variable and initialize it to one, with the do statement, increment the variable by one and print it, then the while statement checks if the variable is less than or equal to 10.

#include <iostream>

using namespace std;

int main(){

   int i = 1;

   do {

       cout<< i << "\n";

       i++;

   }

   while (i <= 10);

}

Explanation:

The C++ source code initializes the integer variable i to one and increments and print the value if the value is less than or equal to ten. The do-while statement executes a block of code before the condition is implemented.

Whitepunk [10]

Answer:

C. The number of items in the column list doesn't match the number in the VALUES list.

<u>Syntax is as follows:</u>

INSERT INTO table_name (column1, column2, column3, ...)

VALUES (value1, value2, value3, ...);
