Hi This is for c Thanks 1Build a function called calculatepe

Hi! This is for c++. Thanks

1.Build a function called calculate_percent() with the following properties:

     Takes 2 floating-point numbers called \"score\" and \"max_score\"

     Returns a floating point number which is percentage of score and max_score.\'

     Do not use a global variable, and do not use printf/scanf inside this function

2.Build a function called getAvg()that returns the average of three numbers

    Takes 3 floating-point numbers

    Returns the average of three numbers.

    Do not use a global variable, and do not use printf/scanf inside this function

3.Build a function called getGradeLetter():

   Takes a floating-point number containing the percentage

    Returns a char which is the letter grade of the percentage.

    Do not use a global variable, and do not use printf/scanf inside this function

4.Build a function called print_line()

   Takes a character that will be used to print a line

   Takes the number of times to print the character

For example, if we call print_line(\'*\', 10), it should print :

********** (Prints * ten times).

Note that when you call this function, you need to provide a char in single quotes.

Solution

float calculate_percent(float score,float max_score)
{
return (score/max_score)*100;
}

float getAvg(float n1,float n2,float n3)
{
return (n1+n2+n3)/3.0;
}

char getGradeLetter(float precent)
{
char grade;
  
if(percent>=90)
grade = \'S\';
else if(percent>=80)
grade = \'A\';
else if(percent>=70)
grade = \'B\';
else if(percent>=60)
grade = \'C\';
else if(percent>=50)
grade = \'D\';
else if(percent>=40)
grade = \'E\';
else
grade = \'F\';
  
return grade;
}

void print_line(char chr,int times)
{
for(int i=0;i<times;i++)
cout << chr;
cout << endl;
}
