This is one the common question to all the computer Engineers. I tried to find the exact answer of this from internet but I can not find Perfect answer of the this qestion. so I am writing this Blog.
Please consider Higher level of programming as strucuture programming lanugauge and assembly language as unstructure programming langugae.
Example of the strucutre programming languge In c#
namespace myfirstclass
{
class Program
{
private string name;
int age;
int maths;
int iis;
int os;
int total = 300;
int marks;
double per;
void pankil()
{
marks = maths + iis + os;
}
{
per = (double)marks / total * 100;
}
double
showper()
{
return per;
}
public string sunita
{
get
{
return name;
}
set
{
name = value;
}
}
public int agee
{
get
{
return age;
}
set
{
age = value;
}
}
}
}
class renu
{
static void Main()
{
Program p = new Program();
p.sunita = "Hello";
p.agee = 10;
Console.WriteLine("{0}
{1}", p.agee, p.sunita);
}
}
}Now Assembly Code for this program. I am showing code of object P only.
