Quesion problem
Hi, well i just need alil help with this question just a few tips and what the question is all about..
Q4.12).Modify the program of fig 4.7 so that it calculates the average grade for the class.
Well the problem is that it says to calculate the average grade well i can do it when the grades were integers but they are Characters how can i find the average of a character????
/* Fig. 4.7: fig04_07.c
Counting letter grades */
#include <stdio.h>
int main()
{
int grade;
int aCount = 0, bCount = 0, cCount = 0,
dCount = 0, fCount = 0;
printf( "Enter the letter grades.\n" );
printf( "Enter the EOF character to end input.\n" );
while ( ( grade = getchar() ) != EOF ) {
switch ( grade ) { /* switch nested in while */
case 'A': case 'a': /* grade was uppercase A */
++aCount; /* or lowercase a */
break;
case 'B': case 'b': /* grade was uppercase B */
++bCount; /* or lowercase b */
break;
case 'C': case 'c': /* grade was uppercase C */
++cCount; /* or lowercase c */
break;
case 'D': case 'd': /* grade was uppercase D */
++dCount; /* or lowercase d */
break;
case 'F': case 'f': /* grade was uppercase F */
++fCount; /* or lowercase f */
break;
case '\n': case' ': /* ignore these in input */
break;
default: /* catch all other characters */
printf( "Incorrect letter grade entered." );
printf( " Enter a new grade.\n" );
break;
}
}
printf( "\nTotals for each letter grade are:\n" );
printf( "A: %d\n", aCount );
printf( "B: %d\n", bCount );
printf( "C: %d\n", cCount );
printf( "D: %d\n", dCount );
printf( "F: %d\n", fCount );
return 0;
}
