Question

this is true and false for C++

(1 point each) Circle T for true or F for false for the following questions. 1. T/F The Boolean expression b1 || b2 evaluates to true if either Boolean value (b1, b2) is true. T/F The code we write in C++ (e.g. code in file project1.cpp) is referred to as source code. 2. 3. T/F The statement float scores[3][3] creates 3 arrays, each containing 3 floating-point variables. T/F For loops work best when the number of iterations is not well defined and while loops 4. work best wh the number of iterations is well defined 5. T/F Avariable's address is the location in memory where that variable's value is stored 6. T/F The statement values[5]: declares an array of 5 elements. T/F A while loop whose statement block contains only the statement cout << 5; can print nothing. 7. T/F 8. Variables declared inside a function may be accessed outside of that function without error. T/F Global variables are variables declared outside of any function body 9. 10. T/F A do-while loop whose statement block contains only the statement cout << 5; can print nothing 11. T/F Areturn statement immediately halts execution of the function it is contained in. 12. T/F Arrays are passed to functions using the call-by-reference mechanism. 13. T/F The arithmetic expression 12/13.0 produces an integer result. 14. T/F Afunction with return type void requires a return statement. 15. T/F The expression a % b produces the remainder of a / b. 16. T/F If array A contains size elements, its set of legal indices is the interval [0, size-1). 17. T/F A for loop whose statement block contains only the statement cout << 5; can print nothing. 18. T/F The insertion operator <c is used to read data from a file while the extraction operator >> is used to wr data to a file (e-g. cout & cin). 19 T/F The goto and return statements may be used anywhere inside a function definition 20. T/F The continue and break statements do NOT depend on any condition to execute.
