Question

Write a C program to calculate the minimum, maximum, and average of n grades entered by the user. The program uses a function int g(int n) to calculate the requirements above and also prints the grades in reverse order. The function should utilize the concepts of recursion and static storage class specifier.

Answer 1

Answer:

#include <stdio.h>

int p;

int g(int n)

{

static int minimum=101, maximum=-1, average=0;

if(n==0)

return -1;

else

{

printf("Enter course grade %d: ",p-n+1);

int grade;

scanf("%d",&grade);

g(n-1);

printf("%d\n",grade);

if(minimum>grade)

minimum=grade;

if(maximum<grade)

maximum=grade;

average=average+grade;

if(n==p)

{

printf("minimum= %d\n",minimum);

printf("maximum= %d\n",maximum);

printf("Average= %.2f\n",(double)average/(double)n);

 

}

return -1;

}

}

int main()

{

printf("Enter the number of grades:\n");

scanf("%d",&p);

g(p);

return 0;

}

Explanation:

• Use a conditional statement to check to find the maximum and minimum grade.
• Check if n is equal to p, then display the values of maximum and minimum.
• Calculate the average by dividing the sum with the total numbers and then display its value.
• Inside the main function, get number of grades from user as an input.
• Lastly, call the function g and pass it the value of grade.
