C Programing Basic Programs

C Programing Basic Programs Using Printf() and Scanf()  Functions

----------------------------------------------------------------------------------------------------

1. Print Simple Welcome message like “Welcome to the world of C Programming”.

    #include<stdio.h>
    #include<conio.h>
     void main()
     {
       clrscr();
     
       printf("Welcome to the world of C Programing");
                   
       getch();
        
     }

•  OUTPUT:

       Welcome to the world of C Programming

-----------------------------------------------------------------

2. Write a C Program to print the following string. (Use of Escape Sequence for “ ” DOUBLE QUOTE)

Someone Said “Nothing is Impossible”.

    #include<stdio.h>

   #include<conio.h>

    void main()

    {                                                   

        clrscr();

printf("\"Nothing Is Impossible\"");

getch();

   }

•  OUTPUT:

        "Nothing Is Impossible"

-----------------------------------------------------------------

3.  Write a C Program to accept Dollar and convert it into  Rupees. (1 Dollar = 70 Rupees)

   #include<stdio.h>

   #include<conio.h>

    void main()

    {      

        int dollar,rupees;//Declare variable

clrscr();

printf("Enter Dollar");

scanf("%d",&dollar);//Get Value From User

rupees=dollar * 70;

printf("Rupees:%d",rupees);

        getch();

      }

•  OUTPUT:

   Enter Dollar: 2 //Get Value From User

   Rupees : 140

-----------------------------------------------------------------

4.  Write a C Program to accept any number and print its  square and cube.

     #include<stdio.h>

    #include<conio.h>

    void main()

    {     

        int no,square,cube;

clrscr();

printf("Enter No");

scanf("%d",&no);

square=no*no;

cube=no*no*no;

printf("Square:%d",square);

printf("Cube:%d",cube);

getch();

    }

•  OUTPUT:

        Enter No: 2

        Square: 4

        Square: 8

-----------------------------------------------------------------

5.  Write a C Program to accept radius and calculate Area of Circle and print it.

  #include<stdio.h>

  #include<conio.h>

void main()

{

float radius,ans;

clrscr();

printf("Enter Radius:");

scanf("%f",&radius);

ans=3.14*radius*radius;

printf("\nArea Of Circule:%f",ans);

getch();

}

•  OUTPUT:

        Enter Radius: 2.5

        Area Of Circule: 22.812500

-----------------------------------------------------------------

6. Write a C Program to get any two values and swap them or exchange them.

 #include<stdio.h>

 #include<conio.h>

 void main()

{

int swap,a,b;

clrscr();

printf("Enter Value For A:");

scanf("%d",&a);

        printf("\nEnter Value For B:");

scanf("%d",&b);

        printf("\nBefore Swapping:");

printf(" \nA :%d" ,a);

printf("\nB :%d",b);

        swap=a;

        a=b;

b=swap;

        printf("\n\nAfter Swapping:");

printf("\nA :%d",a);

printf("\nB :%d",b);

getch();

}

•  OUTPUT:

        Enter Value For A: 10

        Enter Value For B : 20

        Before Swapping:

        A: 10

        B:20

        Before Swapping:

        A: 20

        B: 10
