C Program To Print Greatest Number Among Three Numbers

Greatest number among three numbers:-

In this C program we will print greatest one number among three numbers from user input value. Here we take three int type variables, name as num1, num2, num3  for input first ,second and third number.

  #include<stdio.h>
  int main()
   {
       int num1,num2,num3;
       printf("Enter the first number :");
       scanf("%d",&num1);
       printf("Enter the second number :");
       scanf("%d",&num2);
       printf("Enter the third number :");                       
       scanf("%d",&num3);
          if(num1>num2 && num1>num3)
             {
                  printf("First number is greater than second and third number");
             }
           else if(num2>num3)
             {               
                  printf("Second number is greater than first and third number");
             } 
           else
             {
                printf("Third number is greater than first and second number");
             }  
       return 0;
   } 

Output :

  Program run first time:-
 

  Enter the first number :7
  Enter the second number :16
  Enter the second number :18
  Third number is greater than first and  second number
 
  Program run second time:-
 
  Enter the first number :30
  Enter the second number :20
  Enter the second number :15
  First number is greater than second and third number

C Program To Print Greater Number Between Two Numbers

Greater number between two numbers:-

In this C program we will print greater one number between two numbers from user input value. Here we take two int type variables for input first number and second number.

   /*

      Filename : greatestNumber.c
      IDE Used To Developed : CodeBlocks
      Developed By : Pavito Golui
   */
  #include<stdio.h>
  int main()
   {
       int number1, number2;
       printf("Enter the first number :");
       scanf("%d",&number1);
       printf("Enter the second number :");
        scanf("%d",&number2); 
          if(number1>number2)
             {
                  printf("First number is greater than second number");            
             }
           else
             {               
                  printf("Second number is greater than first number");
             }  
       return 0;
   } 

Output :

  Program run first time:-
 

  Enter the first number : 18
  Enter the second number :12
  First number is greater than second number
 
  Program run second time:-
 
  Enter the first number : 156
  Enter the second number :174
  Second number is greater than first number

C Program To Check Whether A Number Is Even Or Odd

Check Even Or Odd Number:-

What is odd or even number:-
If a number is completely divided by a number and  without giving remainder when dividing, then that number is called even number.
Example-   10/2  remainder 0
                 18/3  remainder 0
if a number is not completely divided by a number and without giving remainder when dividing, then number is called odd number. 
Example-   10/3  remainder 1
                 18/4  remainder 2

In this C program we checks whether a number is even or odd by using Arithmetic Modulus operator. here we take a variable of type int name as number for input a number from the user when program run. 

We check condition if(number%2==0) is true then execute if block otherwise execute else block.

   /*
      Program : Check Even Or Odd Number
      Filename : evenOdd.c
      IDE Used To Developed : CodeBlocks
      Developed By : Pavito Golui
   */
  #include<stdio.h>
  int main()
   {
       int number;
       printf("Enter the number :");
       scanf("%d",&number);
           if(number%2==0)
             {
                  printf("%d is even number",number);            
             }
           else
             {               
                  printf("%d is odd number",number);
             }  
       return 0;
   } 

Output :

   Program Run First Time -

 

  Enter the number : 23
  23 is odd number

  Program Run Second Time -

 

  Enter the number : 6
  6 is even number

C Program Of Calculate Simple Interest

Simple interest:-

In this c program we calculate simple interest of given principle amount, here we take two int type variable, principle and time for principle amount and time  and roi and interest for rate of interest and store interest likewise. 

   /*
      Program : Simple Interest
      Filename : simpleInterest.c
      IDE Used To Developed : CodeBlocks
      Developed By : Pavito Golui
   */
  #include<stdio.h>
  int main()
   {
       int principle, time;
       double roi, interest;
       printf("Enter the principle amount :");
       scanf("%d",&principle);
       printf("Enter the time :");
       scanf("%d",&time);
       printf("Enter the rate of interest :");
       scanf("%lf",&roi);
          interest= ( (principle * roi) /100 ) *time;
      printf("Interest is :%lf",interest); 
       return 0;
   } 

Output :

   Enter the principle amount : 15000
  Enter the time : 3
  Enter the rate of interest : 5  
  Interest is : 2250.000000

C Program Of Addition, Subtraction, Multiplication, Division, Of Two Number By User Input

Addition, Subtraction, Multiplication, Division, of two numbers:-

In this c program, we take two value as input from user, variables num1 and num2 and add, sub, mul, div, for results store, then we perform addition, subtraction, multiplication, division, and of these two numbers. In this program we take all variables double type for performing operation on both number, integer and real.

   /*
      Program : Arithmetic Operation
      Filename : arithmaticOperation.c
      IDE Used To Developed : CodeBlocks
      Developed By : Pavito Golui
   */
  #include<stdio.h>
  int main()
   {
      double num1, num2, add, sub, mul, div;
      printf("Enter the first number :");
      scanf("%lf",&num1); 
      printf("Enter the second number :");      
      scanf("%lf",&num2);
          add=num1+num2;
          sub=num1-num2;
          mul=num1*num2;
          div=num1/num2; 
      printf("Addition is: %lf \n",add);
      printf("Subtraction is: %lf \n",sub);
      printf("Multiplication is: %lf \n",mul);
      printf("Division is: %lf \n",div);   
       return 0;
    }
 

Output : 

  Enter the first number : 100
  Enter the second number :5.5        
  Addition : 105.500000
  Subtraction :  94.500000
  Multiplication : 550.000000  
  Division : 18.181818
