Question

Debugging:

The code below has six errors. The errors may be syntax errors or logic errors, and there may be more than one per line; examine the code carefully to find them. Indicate each of the errors you find by writing the line number and correction in the space provided below.

This program is designed to take a constant number of scores (3 in this case) and store them into an array. Then the array is passed to a function and the average score is returned.

The expected output should be:

-bash-4.1$ ./exam1_debug

Enter score #1:

100

Enter score #2:

91

Enter score #3:

80

The average score was: 90.3333

You must find and correct all six of the errors.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

#include <iostream> using namespace std; const NUM_SCORES = 3; double average(int scores); int main () { int scores[NUM_SCORES]; for(i = 0; i < NUM_SCORES;i++){     cout << "Enter score #" << i+1 << ":" << endl;     cin >> scores[i+1]; } cout << "The average score was: " << scores << endl; return 0; } double average(int scores[]){ int total = 0; for(int i = 0;i < NUM_SCORES;i++){     total += scores[i]; } return (total/NUM_SCORES); }

Line Number	Correction

Answer 1

Dear Student,

Here is the complete correct program....along with the comment. I have specified the error as well as corrected it.

NOTE: Please note that the following program is tested on ubuntu 14.04 system and compiled under g++ compiler....

When you run the above given program then you will get the error messages in each line as indicated below...

Here is the screen shot of the error message.....

--------------------------------------------------------------------------------------------------------------------------------------

------------------------------------------------------------------------------------------------------------------------------------------------

here is the complete correct program....

Program:

-----------------------------------------------------------------------------------------------------------------------------------

#include <iostream>

using namespace std;

//Error 1: Please specify the right data type.
//Here you have intialized the value as const. So value is not goin to change throughtout thr program.

int NUM_SCORES = 3;

//Error 2: Variable i data type is not declared

int i;

double score;

double average(int scores[]);

int main ()

{

int scores[NUM_SCORES];

for(i = 0; i < NUM_SCORES;i++)

{

cout << "Enter score #" << i+1 << ":" << endl;

//Error: 7 you are entering a i+1 value while the for loop start with i = 0;

cin >> scores[i];

}

//Error: 3 avergae calculating function must be called here;

score = average(scores);

//Error: 4 Here we are are displaying scores array that is not a valid operation
//cout << "The average score was: " << scores << endl;

//Correct Statement:

cout << "The average score was: " <<score<<endl;

return 0;

}

double average(int scores[])
{

//Data type Declaration of total, total should be of type double.

double total = 0;

for(int i = 0;i < NUM_SCORES;i++)
{

    total += scores[i];

}

//Error:5 average calculation should be done here then calculate the average

cout<<total<<endl;

double Avg = total/NUM_SCORES;

cout<<Avg<<endl;

//Error:6 only variable can be return here we are returning an expression

return Avg;

}

Here i have attached the output of the program as a screen shot..

Now you can make a table of .with line number and correction required...

Kindly Check and Verify Thanks...!!!
