(TCO 5) Arrays are always passed into a function by location because
(TCO 6) An array is a data type that contains _______.
a fixed number of elements

values that must either be initialized when the array is declared or assigned at runtime
All of the above
(TCO 5) Place function prototypes before main() to
(TCO 5) What is the output of the following code?

{
x[0] = x[0] * 3;
x[1] = x[1] * 3;
x[2] = x[2] * 3;
}

{
int x[] = { 1, 2, 3 };
func(x);

(TCO 6) What is the range of valid subscripts for the following array?

double list[10];
(TCO 6) Given the following array declaration, if the array is stored starting at address 1000, what is the output of the following statement? Assume the code is for a 32 bit processor such as a Pentium.

}
(TCO 6) foo contains _______.

(TCO 6) For the array declared below, what is the sum of list[2] and list[3]?

int list[]= {1,2,3,4,5};
(TCO 5) A variable declared within a block (inside curly brackets) is visible
(TCO 7) A C-Style string which is not null terminated will
(TCO 7) Which of the following functions would correctly copy C string s2 to C string s1?
(TCO 7) Given the followingstringvariable, write a statement that wouldinsert"interesting" before the wordexample
instr1.
string str1 = "Here is an example string";
(TCO 7) Given the followingstringvariable, write a statement that would locate the position of "string" in thestr1variable and store the result in anintvariable namedpos.
string str1 = "Here is an example string";
(TCO 7) Create an output format statement which would generate lines in the table which appear as shown below. The Employee Name Field displays an employee name contained in thenamevariable. YYY displays an integer value from theagevariable which ranges from 1 thru 100 and should be right justified. XXXXX.XX displays a monetary value from thesalaryvariable which ranges from 0.01 to 99999.99 and should also be right justified. Use the variables shown below in your output statements.
Employee Name Field------YYY----$XXXXX.XX
char name[25]; int age; double salary;
(TCO 6) Write a function calledAnalyzeData. This function is passed a double array along with a parameter that indicates the number of elements in the array. It is also passed a double value. The function computes and returns the number of values in the array that are greater than this double value. Write a complete C++ function to do this operation. There is nocinorcoutin this function. This is only a function, so there is no main routine here!
(TCO 5) Write a function that takes inputs of yards and feet (whole numbers) and calculates and returns an output of the total number of miles (a floating-point value). There are 5280 feet per mile. There are 3 feet in a yard. Use appropriate parameter passing and return mechanisms. Use appropriate datatypes. For example, with inputs of 1760 yards and 1320 ft, the result would be 1.25 miles. Use proper code formatting techniques. Do not write a main routine. Your function does not docinorcout.
(TCO 5) Write a function that converts an input of some integer number of inches into outputs of integer numbers of yards, feet, and inches. Do not write a main function. Your function does not docinorcout. Your function will have four parameters. Make sure you use appropriate parameter passing techniques! Your function will be a void function. There are 12 inches in a foot, and 36 inches in a yard. For example, if the total number of inches input is 50, the results are 1 yard, 1 foot, and 2 inches.
(TCO 7) Write a function which takes aC stringas an input and counts the number of non-alphabetic characters in theC string. Non-alphabetic characters include anything outside the ranges 'a' thru 'z' and 'A' thru 'Z'. Do not count the null terminator. You are not allowed to use any other functions to do this. Do not write a main function. Your function does not do anycinorcout. Remember,C stringsare terminated with the '\0' character. Make sure to properly format all your code.
(TCO 7) Write a function which takes twostringvariables (not C strings) as inputs and compares them. If they are equal, the function should return 0. If the firststringis less than the secondstring, return a negative number. If the firststringis greater than the secondstring, return a positive number. You are not allowed to use thecomparemethod of thestringdata type. You must use the comparison operators. Do not write a main function. Your function does not do anycinorcout. Make sure to properly format all your code.
