What is wrong with the following code, if anything? Note: you may assume there are no syntax errors. int a=0;int count;ifstream iFile;int sum=0;iFile.open( "data.txt");if ( iFile.is_open() == false)return;elsedo{iFile>>a;sum += a;if ( iFile.eof())break;}while ( !iFile.eof() );cout << sum << endl;
Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. i becomes ! a becomes @ m becomes M B becomes 8 o becomes . Ex: If the input is: Mypassword The output is: Myp@ssw.rdq*s Write a program to get the above task done. Use switch statement to handle the conditional part of the code.

Question2. Mark the following statements as true or false. 5. Named constant content changes during execution.6. Variables can be initialized when declared.7. Pre-increment is described by: variable ++.8. cin and cout are declared in the header file string.9. Suppose x = 5. After the statement y = x++; executes, y is 5 and x is 6.10. Suppose a = 5. After the statement ++a; executes, the value of a is still 5 because the value of the expression is not saved in another variable.
1Write a for loop that repeats seven times, asking the user to enter a number. The loop should also calculate the sum of the numbers entered and display the final sum. 2Write a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 . . . 1000 What’s the initialization step?
