Question

All in C++ programming language

1.

a.) convert for loop to while loop example

b.) convert while loop to for loop example

2.) pass one dimension array(and its size) to function example

Answer 1

1)

A)

CODE

#include<iostream>

using namespace std;

int main()
{
   //declaring variables
   int i,sum=0;
  
   //for loop for finding sum of intgers from 1 to 5
   for(i=1;i<=5;i++)
   {
       //calculating sum
       sum=sum+i;
   }
   //printing sum
   cout<<"Sum of 1-5 is "<<sum<<endl;
   sum=0;
   i=1;
  
   //while loop for finding sum of intgers from 1 to 5
   while(i<=5)
   {
       //calculating sum
       sum=sum+i;
      
       //incrementing value
       i++;
   }
   //printing sum
   cout<<"Sum of 1-5 is "<<sum<<endl;
   return 0;
}

using namespace std;

int main()
{
   //declaring variables
   int i=1,fact=1;
  
   //while loop for finding factorial of 5
   while(i<=5)
   {
       //calculating factorial
       fact=fact*i;
      
       //incrementing value
       i++;
   }
   //printing factorial
   cout<<"Factorial of 5 is "<<fact<<endl;
   fact=1;
   i=1;
  
   //for loop for finding factorial 5
   for(i=1;i<=5;i++)
   {
       //calculating factorial
       fact=fact*i;
   }
   //printing factorial
   cout<<"Factorial of 5 is "<<fact<<endl;
   return 0;

//function for print an array
void printArray(int functionArray[],int size)
{
   //for loop
   for(int i=0;i<size;i++)
   {
       //printing array
       cout<<functionArray[i]<<endl;
   }
}

int main()
{
   //initializing an array
   int array[5]={1,2,3,4,5};
  
   //finding size of an array
   int size = sizeof(array)/sizeof(array[0]);
  
   //passing array and size to a function
   printArray(array,size);
   return 0;
