C++ Program To Merge Ascending And Descending Array Into The Third Array

#include <iostream>
#include<string.h>
#include<cstdlib>
using namespace std;
int main ()
{
 int s1,s2,a[100],b[100],c[200],i,j,k;

 cout<<"Enter the size of Array 1\n\n";
 cin>>s1;

 cout<<"Enter the first Element of array\n\n";
 
 for(i=0;i<s1;i++)
 {
   cin>>a[i];
 }

 cout<<"Enter the size of Array 2\n\n";
 cin>>s2;

 cout<<"Enter the Second Element of array\n\n";

 for(i=0;i<s2;i++)
 {
   cin>>b[i];
 }

 cout<<"Merge array Are Given Below\n\n";

 i=0;j=0;k=0;
 
 while(i<s1 && j<s2)
 {
   if(a[i]<b[j])
   {
    c[k++]=a[i++];
  }
   else
   {
    c[k++]=b[j++];
  }
 }
 if(i>=s1)
 {
   while(j<s2)
   {
    c[k++]=b[j++];
  }
 }
 else if(j>=s2)
 {
  while(i<s1)
   {
    c[k++]=a[i++];
  }
 }
 for(i=0;i<s1+s2;i++)
 {
   cout<<c[i]<<" ";
 }
 return 0;
}

Output:

Enter the size of Array 1

5

Enter the first Element of array

10 20  30 40 50

Enter the size of Array 2

6

Enter the Second Element of array

110 100 90 80 70 60

Merge array Are Given Below

10 20 30 40 50 110 100 90 80 70 60
