Question

A. Circle if the statement is true and ?if the statement is false. (20 Points-4 Each) TIF When a function is called, flow of control moves to the function's prototype. TF2) It is possible for a function to have some parameters with default arguments and some without. T/F 3) Global variables are initialized to zero by default 4) One reason for using functions is to break programs into manageable units, or TIF modules 5) A static variable that is defined within a function is initialized only once, the first time TIF the function is called B. Answer the following questions. (20 Points, 4 Each) 1) Look at the following function prototype. int myFunction (double); What is the data type of the function's return value? a) int b) double c) void d) Can't tell from the prototype 2) Here is the header for a function named computeValue: void computeValue (int value) Which of the following is a valid call to the function? a) computeValue(10) b) computeValue(10); c) void computeValue(10); d) void computeValue(int x)

Explanation / Answer

Question A:

1) False, when function called flow moves to the function defination

2) YTrue,es, we can have the default arguments

3) True, default values for global variables is 0

4) True,function are used to divide the program into modules

5) True, static variables are initialized only first time

Question B:

1 ) int

2)computeValue(10);

3) C ) 7, getValue() returning the parameter value +5 , here parameter is 2 so 2+5=7

4) B, 1 6 3, here we are b as reference so changes made in the defination will reflect at calling side

Question C:

1)

int getFact(int num){

if(num<0)

return -1;

int fact=1;

for(int i=1;i<=num;i++){   

fact=fact*i;   

}

return fact;

}

2)

char getGrade(double value){

if(value<0 || value>100)

return 'X';

char res;

if(value>=90)

res='A';

else if(res>=80)

res='B';

else if(res>=70)

res='C';

else if(res >=60)

res='D';

else if(res<60)

res='F';

return res;

}
