Problem 1: Basic Mathematical Operations

Create a C program that will input N number and create a function that determines the following SUM, AVERAGE, EVEN Numbers ODD Numbers, Prime Numbers and FACTORIAL of the given N integers.

Consider the following sample output.

Enter N numbers: 10

Value of number 1-3

Value of number 2-3

Value of number 3-7

Value of number 4-3

Value of number 5- 2

Value of number 6- 3

Value of number 7- 45

Value of number 8- 4

Value of number 9 - 3

Value of number 10-19

Sum: 92

Average: 9.2

EVEN Numbers: 2, 4

ODD Number: 3,3,7,7,3,45,3,19

PRIME Numbers: 3,3,7,3,2,3,3

Factorial:

Value 1- 3 = 6

Value 2- 3 = 6

.

.

.

Value 10 – 19 = ?

Code:

#include<stdio.h>
#include<conio.h>
int sum (int);
float ave (float,float);
int even (int);
int main()
{
int count,hold,num,sumall=0;
clrscr();
printf("\nEnter N numbers: "); scanf("%d",&hold);
for (count=1;count<=hold;count++)
{
printf("Value of number %d-",count);
scanf("%d",&num);
sumall=sumall+sum(num);
if (count==hold)
{
printf("\nSum:%d",sumall);
printf("\nAverage:%.1f",ave(sumall,hold));
}
}
getch();
return 0;
}
int sum (int a)
{
int sum1;
sum1=0;
sum1=a+sum1;
return (sum1);
}
float ave (float b, float c)
{
float ave1;
ave1=b/c;
return ave1;
}

I am stuck at average because i don't know what is next now please me
