Basic C Programs

 

 

 

 

 

 

There are many snippets of basic c programs available on the internet, but none of them had a explanation on it.So I will try to illustrate the most common basic c programs and Explain them in Plain language.

1.Largest of three numbers

  • The first one on the list is largest of three numbers using Conditional Operator.

  • A conditional Operator is also called as a Ternary Operator.

  • The syntax of conditional operator is that after the condition it has a true part and an false part

  • If the condition is satisfied the statement after the question mark is executed else the other one.

  • Here in this program we declare 4 variables a,b,c and max.

  • At first we check if a is greater than b if true check for a>c then we assign a as the maximum number to the max variable if first one holds good and second one fails then c is assigned to max

  • If a is smaller then b is checked if it is greater than c then it is assigned to max

  • The Snippet is given below:

2.Fibonacci Series

  • In Mathematics Fibonacci sequence are the integers with the sequence 0,1,1,2,3,5,8,13,21,34….

  • It follows the sequence in which the subsequent numbers are the sum of previous two.

  • Fn=Fn-1+Fn-2 where f0=0 and f1=1.

  • In a C program the most commonly used input output functions are printf and scanf which is avialable at the stdio.h header file.

  • The clrscr() and getch() are available at conio.h header file.

  • At first we assign f1=-1 and f2=1 so that initially we start with a 0.

  • In the for loop from 1 to n we add f1+f2 and store it to f3 and print f3 each time.

  • Then we interchange f2 to f1 and f3 to f2 so that the sequence continues with the new set of numbers.

  • The Snippet is given below:

3.Basic Sorting(Bubble sort)

  • The basic Sorting technique in order to sort a set of integers is the bubble sort.

  • The main concept of bubble sort is compare each pair of adjacent terms and swap them if they are not in order.

  • At the final iteration no swap is needed because the list is sorted.

  • Bubble sort animation
