Question

Having a terrible time with C++ programming & haven't been able to find any real help. Can someone PLEASE provide a pdf or just display a range of C++ programs that I can follow & practice with? Especially programs that involve multiple operations at once (finding the average & difference of values), single operations, compounding interest, passing to functions, void functions, arrays, pass by reference, arrays, any of which that involve floating point values, calling & rewriting functions, inputting sentences, character string, etc... Clearly I don't blame you for not helping & don't expect a guide for everything unfortunately but the littllest help counts. I really need complete programs to follow & use, I've only had pieces of everything it doesn't help.

Explanation / Answer

// These are the basic programs If you will go through all these then you will be able to understand basics of C++. If you need more help then you can comment.

C++ program to calculate sum and average

#include<iostream.h>
#include<conio.h>

void main()
{
float a,b,c,sum,average;
cout<<“Enter three numbers:”;
cin>>a>>b>>c;

sum=a+b+c;
average=sum/3;
cout<<“SUM =”<<sum;
cout<<“Average =”<<average;

getch();
}

Program to calculate Factorial using reccursion

#include<iostream> //header file

using namespace std;

int main()

{

    long long n,fact=1; // long long datatype to store larger values

    cout<<" Enter Number: ";

    cin>>n;

    for(int i=1;i<=n;i++)

    {   fact=fact*i;

    } cout<<"Factorial of the number is : "<<fact<<endl;

     return 0;

}

Compound Interest

#include<iostream.h>
#include<math.h>
void main()
{
float p,r,t,c;
clrscr();cout<<“Enter Principle,Rate and Time “;
cin>>p>>r>>t;
c=pow(p*(1+r/100),t);

cout<<“n”<<“Compound Interest = “<<c<<“%”;
}

Swap 2 numbers using call by reference

#include <iostream>

using namespace std;
void swap (int *a, int *b)
{

int temp;
    temp=*a;
    *a=*b;
    *b=temp;
}

int main(int argc, char *argv[])
{
     int i=5,j=10;
    cout<<"Before swapping I = "<<i<<" J = "<<j<<endl;
    swap(&i,&j);
    cout<<"After swapping I = "<<i<<" J = "<<j<<endl;

    system("PAUSE");
    return EXIT_SUCCESS;

}

Program using arrays

#include <iostream>
using namespace std;

int main() {
    int n[5];
    cout<<"Enter 5 numbers: ";
// Storing 5 number entered by user in an array using for loop. */
    for (int i = 0; i < 5; ++i) {
        cin>>n[i];
    }
  
    cout<<"First number: "<<n[0]<<endl; // first element of an array is n[0]
    cout<<"Last number: "<<n[4];        // last element of an array is n[SIZE_OF_ARRAY - 1]
    return 0;
}

Program for function overloading using floating points values.

#include <iostream>

using namespace std;

/* Function arguments are of different data type */

long add(long, long);
float add(float, float);

int main()
{
   long a, b, x;
   float c, d, y;

   cout << "Enter two integers ";
   cin >> a >> b;

   x = add(a, b);

   cout << "Sum of integers: " << x << endl;

   cout << "Enter two floating point numbers ";
   cin >> c >> d;

   y = add(c, d);

   cout << "Sum of floats: " << y << endl;

   return 0;
}

long add(long x, long y)
{
   long sum;

   sum = x + y;

   return sum;
}

float add(float x, float y)
{
   float sum;

   sum = x + y;

   return sum;
}
