C-program to Convert the octal number into decimal and Vice-Versa



In this C-program we will Convert the Octal Number into Decimal number and Decimal Number into Octal Number. The number will be taken from the user.

input:

The number.(i.e : 5,6,9[Decimal Number] or 12,57,567[Octal Number] etc.)

output:

Octal number will be converted into Decimal number OR Decimal number will be converted into Octal number.

CODE---->


#include<stdio.h>
#include<conio.h>
#include<math.h>
 main()
{
int oct_num,oct,dec_num,dec,remainder,i,n;
printf("***************Welcome to Converter***************");
printf("\n\n\n1.Octal to Decimal\n\n2.Decimal to Octal\n\n Enter Your choice : ");
scanf("%d",&n);
switch(n)
{
case 1:
printf("\nPlease, Enter the Octal number : ");
scanf("%d",&oct_num);
oct=oct_num;
i=0;
dec=0;
while(oct_num!=0)
{
remainder=oct_num%10;
dec=dec+remainder*pow(8,i);
i++;
oct_num=oct_num/10;
}
printf("\nThe decimal of %d is : %d",oct,dec);
break;
case 2:
printf("\nPlease, Enter the Decimal number : ");
scanf("%d",&dec_num);
dec=dec_num;
i=1;
oct=0;
while(dec_num!=0)
{
remainder=dec_num%8;
dec_num=dec_num/8;
oct=oct+remainder*i;
i=i*10;
}
printf("\nThe octal of %d is : %d",dec,oct);
break;
default:
printf("\n SORRY !!! You have Entered a wrong choice.");
break;
}
getch();
}

Linear Queue Program in C-Language

In this C program we will perform operations over Linear Queue ( i.e: Data insert Operation, Data remove Operation and display Operation ). The Choice( i.e: data insert,remove or display ) will be made by the user and The Number will be taken from the user( i.e: For Data insert Operation ). input: The Choice(i.e Data insert, remove or display) & The Number (integers) (i.e. for Data insert Operations) (15,10,128 etc.) output: The Operations will be excecuted as choosen by the user. CODE----> #include<stdio.h> #include<stdlib.h> #define MAXSIZE 10 int Q [ MAXSIZE ], front =- 1 , rear =- 1 ; void qinsert ( int x ) { if ( rear == MAXSIZE - 1 ) printf ( "\n Queue is Full." ); else if ( front ==- 1 ) { front = 0 ; rear = 0 ; Q [ front ]= x ; } else { rear ++; Q [ rear ]= x ; } } void qdelete () { if ( front ==- 1 ) printf ( "\n Queue is Empty." ); else if ( front == rear ) { printf ( ...

C-program of printing "Hello World", 10 times on the screen.

In this C program we will print "Hello World", 10 times on the screen. We will use "body-less-loop" for this C-Program. "Body-less-loop" : it means that the inner part(code block to be executed) of the loop will be empty and the loop will have a semi-colon(;) in it's end. i.e: for ( .....  ; .....  ; .....  ) ; input: Null. output: "Hello World" will be printed on the screen, 10 times. CODE----> #include<stdio.h> int main() {      int i;      for( i=1 ; i ;printf( "   Hello World ! \n ", i++ )) ;      return 0 ; } Don't just read, write it, run it..... RESULT :
