Write a program that determines the total cost of apples given the number of pou

Question

Write a program that determines the total cost of apples given the number of pounds of apples purchased and the cost per pound of apples. Write a program that prompts the user for the lengths of two sides of a triangle and the angle between them (in degrees) and calculates the length of the third site. Write two functions: a function that reads in hours worked and returns the value entered and a separate function that reads in hourly pay rate and returns value entered. a function that displays in a meaningful way the values of its two arguments that represent gross pay and net pay. Write a program fragment that ignores any negative integer values read as data and finds the sum of only the positive numbers. Write a function compress that removes all blanks from its string argument. If the argument is " this Is One " it should be changed to "thisIsOne".

Explanation / Answer

//1.

#include<iostream.h>

void main()
{
   double cost, pounds;

   cout<<"Enter number of pounds of apple purchased";
   cin>>pounds;

   cout<<"Enter cost";
   cin>>cost;

   cout<<"Total cost = "<<(pounds*cost);
}

//2.

#include<iostream.h>

void main()
{
   double s1,s2,s3,ang;

   cout<<"Enter first side";
   cin>>s1;

   cout<<"Enter second side";
   cin>>s2;

   cout<<"Enter angle between 2 sides";
   cin>>ang;

   s3=s1*s1 + s2*s2;

   cout<<"Third side is "<<s3;

}

//3(a).

#include<iostream.h>
int heWork()
{
   int he;
   cout<<"Enter hours worked";
   cin>>hr;
   return hr;
}

double hrRate()
{
   double ra;
   cout<<"Enter hour rate";
   cin>>ra;
   return ra;
}

void main()
{

   int hr;
   double rate;

   hr=heWork();

   rate=hrRate();

}

//3(b).

#include<iostream.h>
void disp(double gr, double net)
{
   cout<<"Hello!!! Your Gross Pay is="<<gr<<endl;
   cout<<"Your Net Pay is="<<net<<endl;
  
}

void main()
{

   double gr=1455, net=900.5;

   disp(gr,net);
}

//4.

#include<iostream.h>

void main()
{

   int i=0,sum=0,n;

   while(i<5)
   {  
       while(1)
       {
           cout<<"Enter number";
           cin>>n;

           if(n>0)  
               break;
       }
       sum=sum+n;
       i++;
   }

   cout<<"Sum is "<<sum;
}
