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 ; }

OR Gate





OR Gate


  • Introduction :-
    • The OR Gate performs logical addition, commonly known as OR function. The OR Gate has two or more inputs and only one output. The operation of OR Gate is such that a HIGH (1) on the output is produced when any of the input is HIGH (1). The output is LOW (0) only when all the inputs are LOW (0).
  • Logic Expression :-
    • If A and B are the input variables of an OR Gate and Y is it's output, then,
    Y = A + B
  • Truth-Table :-

    • Truth-Table of OR Gate
  • Logic Symbol of 2-input OR Gate :-

    • Logical symbol of 2-input OR Gate
  • OR Gate's IC-base diagram :-

    • OR-Gate's IC-base diagram
  • Apparatus :-
    • Bread-board, LED-light, Battery(Power-Supply), IC-7432, Multimeter and Resistance.
  • Procedure :-
    •      1. Verify whether all the wires and components are in good condition.
         2. Set-up OR Gate circuit and feed all the input combinations.
         3. Observe the output corresponding to input combinations and enter it in the Truth-Table.
  • Experimental-data :-
  • Precaution & discussion :-
    •       i> The continuity of the connecting terminals should be checked before      going.
         ii> It should be care that the values of the components of the circuit is      does not exceed to their ratings(Maximum value).
         iii> Before, the circuit connecting, it should be check out, working      condition of all the components.

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 ( "

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..... RESULT :

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<=10 ;printf( "   Hello World ! \n ", i++ )) ;      return 0 ; } Don't just read, write it, run it..... RESULT :
