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 ; }

String Compare using strcmp() function in C Language



In this C program we will compare two strings using strcmp() fuction. The Strings will be given by the User.

strcmp() function compares two strings in this program, if two strings are identical (i.e: "Hello" and "Hello" are identical), then the function returns a integer value Zero "0" else, it returns a non-zero value.
If it returns -1 then it means, the first mis-match occured between a Higher-case and a Lower-case value.(i.e: Apple and apple)
If it returns +1 then it means, the first mis-match occured between a Lower-case and a Higher-case value.(i.e: apple and Apple)
Obviously the function strcmp() is case-sensitive.
strcmp() takes two arguements.
Like : strcmp(string1,string2);

Learn about different string functions and their use: Different String Functions

input:

The two Strings.

output:

The strings are identical or not, will be printed on the screen.

CODE---->


#include<stdio.h>
#include<string.h>
int main()
{
 int i;
 char str1[100],str2[100];
 printf(" Please, Enter the first string: ");
 gets(str1);
 printf(" Please, Enter the second string: ");
 gets(str2);
 i=strcmp(str1,str2);
 if(i==0)
  printf("\n Both String are same.");
 else
  printf("\n The given string are not same.");
 return 0;
}

Don't just read, run on your pc !!!


RESULT :


 Please, Enter the first string: Hello World
 Please, Enter the second string: Hello World

 Both String are same.
--------------------------------
Process exited after 15.78 seconds with return value 0

 Please, Enter the first string: Hello World
 Please, Enter the second string: Hello ProgramJoy

 The given string are not same.

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 :
