  while(m!=n)
  {
      if(m>n)
      {
          m=m-n;
      }
      else
      {
          n=n-m;
      }
  }
  printf("%d",m);
  return 0;
}

Q2. Write a  C++ Program to Change Decimal Number to Binary?

#include <iostream> 
namespace std; 

int main()  
{  
int a[10], n, i;    
cout<<"Enter the number to convert: ";   
cin>>n;   
for(i=0; n>0; i++)    
{   
a[i]=n%2;   
n= n/2; 
}   
cout<<"Binary of the given number= ";   
for(i=i-1 ;i>=0 ;i--)    
{   
cout<<a[i];   
}   
}  

Q 3.C++ Program to generate Fibonacci Triangle

#include   
using namespace std;  
int main()  

  int a=0,b=1,i,c,n,j;    
  cout<<"Enter the limit: ";  
  cin>>n;   
    for(i=1; i<=n; i++)    
   {    
       a=0;    
       b=1;    
        cout<<b<<"\t";  
        for(j=1; j<i; j++)  
       {    
           c=a+b;    
          cout<<c<<"\t";   
           a=b;    
           b=c;  
       }    
        cout<<"\n";   
   } 
return 0;  
}  

Q 4. What is the Output of the program

include
Using namespace std;
int main()
{
int a=5,b=10,c=15;
int*arr[]={&a,&b,&c};
cout<<arr[1];
return 0;
}
  • 5
  • 10
  • 15
  • It will print their address of variable b.

Indexing always start from 0 so arr[1] will print second element in the list therefore & stores the addresss of that particular variable so arr[i] will print the address of variable b.

Ans-d

Q 5. What is the Output of the program

include 
Using namespace std;
int main()
{
Char arr[20];
int i;
for(i=0;i<10;i++)
*(arr+i)=65 +1;
*(arr+i)=0;
cout<<arr;
return(o);
}
  • ABCDEFGHIJ
  • AAAAAAAAAA
  • JJJJJJJJ
  • None of the above
Solution:-A

Q 6. What is the Output of the program

#include 
Using namespace std;
int main()
{
char*ptr;
Char Str[]="abcdefg";
ptr=Str;
ptr+=5;
cout<<ptr;
return 0;
}
  • fg
  • cdef
  • defg
  • abcd
Solution:-B
