Question

Write C program to take four integer inputs from user (A, B, C, D) then, your program should return the sum of even numbers (if there any even numbers) and the multiplication of the odd numbers (if there any odd numbers). For example: if A=1, B=2, C=3, D=4, your program will return: sum=6, multiplication=3. if A=6, B=2, C=8, D=4, your program will return: sum=20, multiplication=0. if A=1, B=3, C=5, D=4, your program will return: sum=4, multiplication=15.

#include <stdio.h>

void getSumProduct(int A,int B,int C,int D,int* sum,int* product){
    if(A%2==0){
        *sum += A;
    }
    else{
        *product *= A;
    }
    if(B%2==0){
        *sum += B;
    }
    else{
        *product *= B;
    }
    if(C%2==0){
        *sum += C;
    }
    else{
        *product *= C;
    }
    if(D%2==0){
        *sum += D;
    }
    else{
        *product *= D;
    }
}
int main(){
   int A, B, C, D, T;
   int sum = 0, product = 1;
   
   printf("Enter value for A: ");
   scanf("%d",&A);
   
   printf("Enter value for B: ");
   scanf("%d",&B);
   
   printf("Enter value for C: ");
   scanf("%d",&C);
   
   printf("Enter value for D: ");
   scanf("%d",&D);
   
   getSumProduct(A,B,C,D,&sum,&product);
   if(product==1)
    product = 0;
   printf("sum=%d, multiplication=%d.\n",sum,product);
   return 0;
}
