Basic Example Of C 



C Program to check whether the given integer is positive or negative 

/* Description: A program to check whether the input
 * integer number is positive or negative. 
 * Written by: Santosh Asole
 */
#include <stdio.h>
 
void main()
{
    int num;
 
    printf("Enter a number: \n");
    scanf("%d", &num);
    if (num > 0)
        printf("%d is a positive number \n", num);
    else if (num < 0)
        printf("%d is a negative number \n", num);
    else
        printf("0 is neither positive nor negative");
}

Output 1:

Enter a number:
0
0 is neither positive nor negative

Output 2:

Enter a number:
-3
-3 is a negative number

Output 3:

Enter a number:
100
100 is a positive number

Program to find largest of three input numbers

#include<stdio.h>
int main()
{
   int num1,num2,num3;
   
   //Ask user to input any three integer numbers
   printf("\nEnter value of num1, num2 and num3:");
   //Store input values in variables for comparsion
   scanf("%d %d %d",&num1,&num2,&num3);

   if((num1>num2)&&(num1>num3))
      printf("\n Number1 is greatest");
   else if((num2>num3)&&(num2>num1))
      printf("\n Number2 is greatest");
   else
      printf("\n Number3 is greatest");
   return 0;
}
Output:
Enter value of num1, num2 and num3: 15 200 101
 Number2 is greatest

Syntax/Format of C program

C Programs A C program can vary from 3 lines to millions of lines and it should be written into one or more text files with extension ".c"; for example, hello.c. You can use "vi", "vim" or any other text editor to write your C program into a file. Before we study the basic building blocks of the C programming language, let us look at a bare minimum C program structure so that we can take it as a reference in the upcoming chapters.     Syntax/Format of simple C program main ()  <--------------------- Function name  {  <------------------------------ Start of program         ........         ........  <------------------- Program statement         ........  }  <------------------------------ End of program      Hello World Example A C program basically consists of the following parts − • Preprocessor Commands • Functions • Variables • Sta...

Loop In C Language

Loop In C Language  A loop statement allows us to execute a statement or group of statements multiple times. Given below is the general form of a loop statement in most of the programming languages − C programming language provides the following types of loops to handle looping requirements. Sr.No. Loop Type & Description 1 while loop Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. 2 for loop Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable. 3 do...while loop It is more like a while statement, except that it tests the condition at the end of the loop body. 4 nested loops You can use one or more loops inside any other while, for, or do..while loop. While Loop in C A while loop is the most straightforward looping structure. While loop syntax in C programming language is as follows: Syntax of While Loop in C: while (condition) { st...

Data Types in C

 Data Type in C Programming Type of data is know as Data type. int,float,char are example of data type in c There are two types 1. Primary data type 2. Derived data type. Primary data types Integer(int),floating(float),character(char),void are the primary data type Derived data types  arrays, functions, structures and pointers are Derived data types. Integer type Integers are used to store whole numbers. Floating type Floating types are used to store real numbers. Character type Character types are used to store characters value. void type void type means no value. This is usually used to specify the type of functions.
