Question

Write a program that will ask the user to enter 4 quiz scores. These scores should be from 0 to 100. Use a procedure and pass by reference to get these scores. Write a function that will find the lowest score. This score will be sent back through the function call. You still need to pass the scores by value to this function. Write a function that will calculate the average score. This value will be sent back to main through the call. Pass the scores and low by value. Now write a procedure that will display the scores, the lowest score and average. This is a procedure and will return nothing to main.

Answer 1

Here is the answer..

CODE:

#include<stdio.h>
void getValues(int *a,int *b, int *c, int *d){
   printf("\nEnter first quiz score: ");
   scanf("%d",a);
   printf("\nEnter second quiz score: ");
   scanf("%d",b);
   printf("\nEnter third quiz score: ");
   scanf("%d",c);
   printf("\nEnter fourth quiz score: ");
   scanf("%d",d);  
}
int getLowest(int a, int b, int c, int d){
   if(a<b && a<c && a<d)
       return a;
   if(b<a && b<c && b<d)
       return b;
   if(c<a && c<b && c<d)
       return c;
   if(d<a && d<b && d<c)
       return d;}
float getAvg(int a,int b,int c, int d) {
   return (float)(a+b+c+d)/4;}
void display(int low, float avg) {
   printf("\nlowest : %d",low);
   printf("\nAverage : %f",avg);   }
int main() {
   int a,b,c,d;
   getValues(&a,&b,&c,&d);
   int low=getLowest(a,b,c,d);
   float avg=getAvg(a,b,c,d);
   display(low,avg);
}

OUTPUT:

CPP CODE:

#include <iostream>
using namespace std;
void getValues(int *a,int *b, int *c, int *d){
   cout<<"\nEnter first quiz score: ";
   cin>>*a;
   cout<<"\nEnter second quiz score: ";
   cin>>*b;
   cout<<"\nEnter third quiz score: ";
   cin>>*c;
   cout<<"\nEnter fourth quiz score: ";
   cin>>*d;   }
int getLowest(int a, int b, int c, int d){
   if(a<b && a<c && a<d)
       return a;
   if(b<a && b<c && b<d)
       return b;
   if(c<a && c<b && c<d)
       return c;
   if(d<a && d<b && d<c)
       return d;}
float getAvg(int a,int b,int c, int d) {
   return (float)(a+b+c+d)/4;}
void display(int low, float avg) {
   cout<<"\nlowest : "<<low;
   cout<<"\nAverage : "<<avg;   }
int main() {
   int a,b,c,d;
   getValues(&a,&b,&c,&d);
   int low=getLowest(a,b,c,d);
   float avg=getAvg(a,b,c,d);
   display(low,avg);}
