 Overview of C - Notes

 

Importance of C Programming:

  •  C is a robust language and has a rich set of built in functions, data types and operators which can be used to write any complex programs.
  • Program written in C are efficient and fast due to availability of several data types and operators.
  • C has the capability of an assembly language with the feature of high level language, so it is well suited for writing in both system software and application software.
  • C is highly portable language, code written in one machine can be moved to other which is very important and powerful feature.
  • C also supports low level features like bit level programming.
  • C has high level constructs and it is more user friendly as its syntaxes approaches to English like language.


History of C Language:

                In 1972, Dennis Ritchie developed a programming language at the AT&T Bell Laboratories in USA, called C Language. It was developed to be used in UNIX operating system. Dennis Ritchie was the Co-developer of UNIX operating system.

C Program to input and display details of students using structure

 C Program to input and display details of students using structure.       In this example, we will enter the details of students like roll number, name and total marks using structure and will be displayed. The total number of student should be entered according to the requirements of the user(maximum value is 50). We can increase the maximum number by changing the statement struct student[50];  to struct student[100];     Here in the output we have entered details of four student and displayed them accordingly. PROGRAM #include <stdio.h> #include <conio.h> struct   student {      int   roll ;      char   name [ 20 ];      int   total ; }; void   main () {      int   i , n ;      struct   student   std [ 50 ];      printf ( "Enter the number of students ...

C Program to Check a Whether a Number is Divisible by 5 or Not

 C Program to Check a Whether a Number is Divisible by 5 or Not            In this program we will check a number entered by the user will be divisible by 5 or Not. We have solved this problem using if-else statement. Program: #include <stdio.h> #include <conio.h> int  main() {      int  x;     printf( "Enter a number" );     scanf( "%d" ,&x);      if (x% 5 == 0 )         printf( "The number %d is divisible by 5" ,x);      else         printf( "The number %d is not divisible by 5" ,x);      return   0 ; } Output: NOTE:   You Can Comment Your Code if you have solved differently and we will pin it in the comment section.  Let's Learn toget...

C program to calculate area of a circle using function.

C program to calculate area of a circle. In this example we will learn to calculate the area of a circle. Here in this program we will use 3.14 as the value of pi.  The formula to calculate the area of a circle is:                                                         area=   π  r² Flowchart To Calculate the Area of a Circle: PROGRAM: #include <conio.h> #include <stdio.h> int   main () {      float   radius , area ;      printf ( "Enter the radius of the circle : " );      scanf ( "%f" ,& radius );      area = 3.14 * radius * radius ;          printf ( "Area of the circle is : %.2f" , area );  ...

C Program to Generate Multiplication Table according to User Choice.

 C Program to Generate Multiplication Table according to User Choice.     In this program, we will learn how to print a multiplication table according to any positive number entered by the user. This program uses for loop to solve this problem.  C PROGRAM TO GENERATE MULTIPLICATION TABLE: # include < stdio.h > # include < conio.h > int   main () {      int   i , num , res = 0 ;      printf ( "\n Enter the multplication table you want :  " );      scanf ( " %d " ,& num );      printf ( "\n\n\n\t MULTIPLICATION TABLE OF  %d \t" , num );      printf ( "\n -------------------------------------------------- \n" );      for ( i = 1 ; i <= 10 ; i ++)      {          res = num * i ;       ...

C Program to print the first N even numbers in reverse order.

 C Program to print the first N even numbers in reverse order.      In this example, we will print the first N even numbers in reverse order. Here N is the total number of even numbers you want to print. PROGRAM TO PRINT THE FIRST N EVEN NUMBERS IN REVERSE ORDER: #include <stdio.h> #include <conio.h> int   main () {      int   even , n , i ;      printf ( "Enter the value of N : " );      scanf ( " %d " ,& n );      printf ( "Printing first  %d  even numbers in reverse order : " , n );      for ( i = n * 2 ; i > 2 ; i --)     {          if ( i % 2 == 0 )         {              printf ( " %d \t " , i );  ...
