Questions 1) A tricky question:
Let's say int n = 7. What is the effect of:
a) if ( n = = 3) cout << "Hello"
b) if ( n = 3) cout << "Hello"
Why ? (Hint: it has to do with the assignment operation and what it returns. Look it up)
2) When you call a function, as in the area and perimeter of a past assignment, you include the values to be sent to the function (the arguments) in parentheses. The function must have been defined with parameters of an equivalent type, that will be
used to receive those values. If the function is called using variables, as in cout << area(length, width) for instance, what is passed to the parameters is a copy of the values in those variables. This is called call-by-value. In that case, the receiving parameters in the fucntion are initialized to the contents of the two argument variables (length and width, in our example). Based on this, given the following function: void f (int i ) { i = 57; } assuming it is called like this: f(value) where value is a variable of type int, defined as int value = 9; what would be the result of printing variable value after the call? Explain
C++ Program
Write a program that prints letter grades based on a score (between 0 and 10) entered from the keyboard. The simplified scoring system will be: 9-10 A 8 B 7 B6 C+ 5 C 4 D+ 0-3 F
Write two functions as part of the same program: if_grade and switch-grade. Both will take the integer score as input and print the letter grade. The if_grade function will accomplish this with if-else, the switch_grade function will use a switch statemen
