foo=

char s[] = "foo";



What expression is always true? - ANSWERS|| = or, && = and, therefore, (p || !p) is always true



Global Variable - ANSWERSis accessible to any function that wants to use it



Local Variable - ANSWERSa specific type of variable that are only available within the context of a
particular expression and can only be accessed within the function that defines them.



Character variables in C are passed to functions... - ANSWERSby value



How to write Radius^2? - ANSWERSpow(radius, 2)



Steps to using a file in a program? - ANSWERS1. Open file with file pointer:

-File*inputFile;

-inputFile=fopen("file_for_opening.txt", "r" or "w");

2. Verify it was opened and print error if not:

-if(inputFile != NULL){} else {/*something went wrong*/ printf("Error opening input file\n");}

3. Using File (read or write):

,-fscanf((filepointer, extra parameter), formatstring, $var1, ..., &varN);

-fprintf(filepointer, formatstring, var1, ... , varN);

4. Close file:

-fclose(inputFile);



How to read from a file? - ANSWERSUse function: fscanf(filePointer, formatSpecifier, &var1, ..., &varN)



What happens when you write to a file? - ANSWERSIf it already contains data, that data will be over
written



Function for write data - ANSWERSfprintf(filePointer, formatString, &var1, ... , &varN)



How do you declare an array of unknown values? - ANSWERStype array [number]



How to declare an array of known values? - ANSWERStype array [] = {number1, number2,...}



Printing an array - ANSWERSprintf("%format",array[])



Pass-by-value mechanism - ANSWERSThe value of the actual parameter is copied and passed to the
formal parameter. It is used for primitive data types (int, char, double)



Pass-by-address mechanism - ANSWERSThe address of the actual parameter is passed to the formal
parameter. This permanently alters the actual parameter. Used for arrays with functions.



Event Controlled Loop - ANSWERSexecutes until some event occurs, you don't know ahead of time how
many times loop will execute (ex: while or do-while loops)



Counter Control Loop - ANSWERSexecutes a fixed number of times, you know ahead of time how many
times loop will execute (ex: for loops)

<= less than or equal to

>= greater than or equal to

!= not equal to

== equal to



Algorithm - ANSWERSunambiguous sequence of step-by-stpe instructions for solving a problem



When testing floating point values for accuracy we must give within a range because points cannot be
exact, what expression must we use? - ANSWERSex: num value is 0.3, within 0.0001 accuracy-

(fabs(num-0.3)<0.0001)



How to set up a for loop? - ANSWERSfor(initial_statement, booleanExpression; post_in/decrement)

initial: initiales variable

boolexp: true or false
