Question

Write a complete C program that accepts 15 float grades into an array ana prints out the array along with the letter grade of each number. At the end print out the highest grade, the lowest grade and the average grade of the class. Use a for loop in main to load the array. Write two functions: displayGrade, which will print out the number and the letter grade; and calcGrade, which will determine the highest grade and the lowest grade and the average grade of the class and pass these three variables back to main to be printed. You may not use global variables.

Explanation / Answer

#include <stdio.h>

int main() //Program Start

{

float numbers[10],result;      //definition of float variables and numbers[10] is a array

int i,p,k;       //definition of integer variables

printf("The program take 15 float numbers and organize in decreasing order. ");

     //print message to enter 15 numbers

printf("enter 15 numbers:(Note:enter one number and press enter) ");

for(i=0;i<15;i++)     //loop for input

scanf("%f",&numbers[i]);      //the input numbers are save in numbers[i]

//print message of the numbers the user enter

printf("Numbers that you enter are: %f %f %f %f %f %f %f %f %f %f ",numbers[0],numbers[1],numbers[2],numbers[3],numbers[4],numbers[5],numbers[6],numbers[7],numbers[8],numbers[9]);

//print a message of the numbers in decreasing order

printf("decreasing order: ");

for(i=10;i>=0;i--)     //loop for compare the numbers enter

{ for(k=10;k>=0;k--)      //loop for compare the numbers with the array numbers[k]

{ if(numbers[i]<numbers[k])   //compare

{

result=numbers[i]; //save number

numbers[i]=numbers[k]; //save the greater number one after another

numbers[k]=result; } } }

//print the numbers in decreasing number

printf(" %f %f %f %f %f %f %f %f %f %f ",numbers[0],numbers[1],numbers[2],numbers[3],numbers[4],numbers[5],numbers[6],numbers[7],numbers[8],numbers[9]);

// Message to exit the program

printf ("Press any botton and enter ");

scanf ("%x",&p);

}
