# How to write algorithm in c program?

It is very easy to write the program for seeing the algorithm.

Most of the problems that we are write with seeing the algorithm only.

Algorithm is very easy to write the any source code seeing this is very useful to write the program

### Is it mandatory to write an algorithm before every program?

Not every program, no. An algorithm describes the procedural steps required to solve a particular problem using natural language. A program usually consists of many such algorithms, each of which can be defined as a function or a series of functions encapsulated by a class. The more trivial the function the less likely you need to write an algorithm.

### How do you write algorithm in c-program?

Here is a simple program that will tell you how to make an algorithm: int main(); { int length; int width; int total; printf("What is the width: "); scanf("%d", &width); printf("What is the length: "); scanf("%d", &length); total = width * 2 + 2 * length; /*Here is the algorithm for finding the perimeter of a square*/ printf("The perimeter is: %d", total); return 0; } Output: What is the width: 32 What is the length…

### How does an algorithm relate to a computer?

To make a computer do anything, you have to write a computer program. To write a computer program, you have to tell the computer, step by step, exactly what you want it to do. The computer then executes the program, following each step mechanically, to accomplish the end goal. When you are telling the computer what to do, you also get to choose how it's going to do it. That's where computer algorithms come in…

### Write algorithm of a largest number in three numbers in 30 steps?

This can be done in fewer than 30 steps. algorithm largest_of_three (A, B, C) is if A>B then temp=A else temp=B if temp>C then return temp else return C From this we can see that the algorithm can be refactored to produce a much simpler algorithm: algorithm largest_of_two (A, B) is if A>B then return A else return B algorithm largest_of_three (A, B, C) is return largest_of_two (largest_of_two (A, B), C)

### How do you write an algorithm for a C program?

An algorithm is simply a description of the logical step-by-step procedure required to solve a particular problem. You do not write algorithms in C (or indeed in any programming language) you write them in your native language (such as English). Algorithms that employ loops or conditional expressions are typically presented using a flowchart to better visualise the implementation of complex algorithms, however all complex problems can be broken down into a sequence of much simpler…
