Question

THIS IS A C PROGRAM. I AM HAVING MULTIPLE ERRORS.
PLEASE ANSWER HOW CAN I FIX MY ERRORS, BRAINLIEST WILL BE MARKED
MY PROGRAM IS ABOUT CALCULATING AVERAGE AND PERCENATGE OF MARKS OF THREE SUBJECTS THROUGH A FUNCTION

#include
int main()
{
void averper(int,int,int,int,int,int);
int num1,num2,num3,aver,per,max;
printf("Enter the marks of subject 1: ");
scanf(" %d",&num1);
printf("Enter the marks of subject 1: ");
scanf(" %d",&num2);
printf("Enter the marks of subject 1: ");
scanf(" %d",&num3);
printf("Enter the maximmum marks: ");
scanf(" %d",&max);
averper(num1,num2,num3,&aver,&per,max);
printf("The average = %d",aver);
printf("The percenatge = %d",per);
return 0;
}
void averper(int a,int b,int c,int *d,int *e,int f)
{
*d = (a+b+c)/2;
*e = ((a+b+c)/f)*100;
}

Answer:

#include <stdio.h>

main()

{

int a,b,c,d,e,f;

char A,B,C,D,E;

printf("Insert Name and Birthday(date only) 1 : \n\a");

scanf("%d",a);

scanf("%s",A);

printf("Insert Name and Birthday(date only) 2 : \n");

scanf("%d",b);

scanf("%s",B);

printf("Insert Name and Birthday(date only) 3 : \n");

scanf("%d",c);

scanf("%s",C);

printf("Insert Name and Birthday(date only) 4 : \n");

scanf("%d",d);

scanf("%s",D);

printf("Insert Name and Birthday(date only) 5 : \n");

scanf("%d",e);

scanf("%s",E);

printf("NO.1 Name : %s Birthday : %d\n\a",a,A);

printf("NO.1 Name : %s Birthday : %d\n",b,B);

printf("NO.1 Name : %s Birthday : %d\n",c,C);

printf("NO.1 Name : %s Birthday : %d\n",d,D);

printf("NO.1 Name : %s Birthday : %d\n",e,E);

printf("%d+%d-%d*%d/%d",a,b,c,d,e);

}
