Hi, I'm making a program that calculates grade by using Terminal.

Here's what I've got.

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

#include

using namespace std;

const int MAX_CHAR = 100;

const int MIN_A = 90;

const int MIN_B = 80;

const int MIN_C = 70;

double getAvg();

char determineGrade(double);

void printMsg(char grade);

int main()

{

double score;

char grade;

score = getAvg();

grade = determinGrade(score);

printMsg(grade);

return 0;

}

double getAvg()

{

double finalAvg;

cout << "Please enter your final average: ";

cin >> finalAvg;

while(!cin)

{

cin.clear();

cin.ignore(MAX_CHAR, ' ');

cout << "input has to be numerical!" << endl;

cin >> finalAvg;

}

cin.ignore(MAX_CHAR, ' ');

return finalAvg;

}

char determinGrade(double finalAvg)

{

char grade = 'F';

if(finalAvg >= MIN_A)

{

grade = 'A';

}

else if(finalAvg >= MIN_B)

{

grade = 'B';

}

else if(finalAvg >= MIN_C);

{

grade = 'C';

}

return grade;

}

void printMsg(char grade)

{

char msg[MAX_CHAR];

switch(grade)

{

case 'A':

strcpy(msg, "Excellent!");

break;

case 'B':

strcpy(msg, "Good job!");

break;

case 'C':

strcpy(msg, "You've passed!");

break;

default:

strcpy(msg, "Need to put down that video game!");

break;

}

cout << msg << endl;

}

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

And I typed the command "g++ -Wall -g app.cpp -o Lab2" to check if it works well, then I found some error.

It says,

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

app.cpp: In function int main():

app.cpp:19:29: error: determinGrade was not declared in this scope

grade = determinGrade(score);

^

app.cpp: In function char determinGrade(double):

app.cpp:52:7: warning: this if clause does not guard... [-Wmisleading-indentation]

else if(finalAvg >= MIN_C);

^~

app.cpp:53:2: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the if

{

^

app.cpp: In function void printMsg(char):

app.cpp:65:28: error: strcpy was not declared in this scope

strcpy(msg, "Excellent!");

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

Can you list all of bugs, both syntax and semantic, that you have found and fixed?

you need to use gdb to find the semantic bug as well.

Thanks.
