i think the question is for assembly not

because of the following words

instruction

dup

but for c this is a solution

#include<iostream>
#include<string>
using namespace std;

int main()
{
	char FullName[100];
	cout<<"Please Enter Full Name"<<endl;
	int i=0;
	gets(FullName);
	while(FullName!=NULL)
	{
		FullName=tolower(FullName);
		i++;
	}

	cout<<FullName<<endl;
	system("pause");
	return 0;
}

THANKS
