Mathematics Structure And Method
what is the use of algorithm in computer science?
http://en.wikipedia.org/wiki/List_of_computer_science_fields
in this page i have read about a topic algorithms but i did not understand what the whole topic is saying
except a statement “In mathematics, computer science, and related subjects, an algorithm is an effective method for solving a problem expressed as a finite sequence of instructions”.
and what is he doing in computer science subcategory, i mean its not a subcategory no one can get job in this field(algorithm)!because its not a field its just the rough structure of creating a programme!
please help me if you know about the topic.thanks
An algorithm is an effective method for solving a given problem.
It is sequence of instructions that tells how the problem can be addressed and solved.
Algorithm is the basis for any programming and falls under the computer science. However it is not mandatory as algorithm can be used in daily life also,just like making tea. You think algorithm for making tea.
Every program is structured and must follow the specified guidelines. This is structural behavior.
But algorithm gives the steps for the program. With logical induction, we can find the solution, but to do in program we need to use the appropriate algorithm.
For example to add two numbers in program.But before that we write algorithm for that.
Algorithm:
————————————-
1. Input two numbers a and b
2. For another variable c,
c=a+b
3. Display c
Program:
———————–
void main()
{
int a,b;
int c;
scanf(“%d,%d”,&a,&b);
c=a+b;
printf(“Sum=%d”,c);
}

This may look simple and may not need algorithm. But think of writing a gaming program like Mario, you need to keep track of what you do and what happens. The algorithm for the components manipulation is necessary. Organization is the essential part and algorithm helps in it.
