C programs QnA

Q. If sum of two integer is 14 and if one of them is 8 then find other integer. Ans: Well, this is very simple. Simply, one integer is 8 and sum of two integers is 14. So, we need to subtract the number 8 from their sum of 14 to get the second number. So, the second number is: 14 - 8 = 6 C-Program of this task Code---> #include<stdio.h> int main () { int num1 = 8 , num2 , sum = 14 ; num2 = sum - num1 ; printf ( "The second number is: %d" , num2 ); return 0 ; }

C-program to Convert Binary Number to Decimal Number and Vice-Versa



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

input:

The number.(i.e : 5,6,9[Decimal Number] or 1100,1010,1111[Binary Number] etc.)

output:

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

CODE---->


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

Calculate sum of 5 numbers using Array in C-language

In this C -program we will scan the numbers using array and then we will calculate the sum of the given numbers, also using array. The numbers will be taken from the user. input: 5 numbers.(i.e : 5,6,9,56,548) output: The sum of the given numbers will be printed on the screen. CODE----> #include<stdio.h> #include<stdlib.h> main() { int arr[5],i,sum=0; printf ("       Enter Five numbers : "); for ( i=0 ; i<5 ; i++ ) {       scanf (" %d ",&arr[i]); } for ( i=0 ; i<5 ; i++ ) {      sum=sum+arr[i]; } printf (" \n      The sum of the given 5 numbers is : %d\n ",sum); system (" pause "); } Don't just read, write it, run it.....

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 :
