,2. Arithmetic Operator in C programming
ARITHMETIC
OPERATION EXAMPLE
OPERATORS
+ Addition 10 + 2 = 12
– Subtraction 10 – 2 = 8
* Multiplication 10 * 2 = 20
/ Division = 5
Modulus – It returns the remainder 10 % 2 = 0 (Here remainder is zero). If it is 10
%
after the division % 3 then it will be 1.
Question-1 :The distance between two cities (in km.) is input through the keyboard. Write a program to convert
and print this distance in meters, feet, inches and centimeters.
#include<stdio.h>
int main()
{
float km,m,cm,ft,i;
printf("Enter The Kilometer : ");
scanf("%f",&km);
m=km*1000;
cm=m*100;
i=cm/2.54;
ft=i/12;
printf("\n KM : %0.2f",km);
printf("\n M : %0.2f",m);
printf("\n CM : %0.2f",cm);
printf("\n IN : %0.2f",i);
2
, printf("\n FT : %0.2f",ft);
return 0;
}
Output
Enter The Kilometer : 30
KM : 30.00
M : 30000.00
CM : 3000000.00
IN : 1181102.38
FT : 98425.20
2.Calculate the sum of digits
#include<stdio.h>
int main()
{
int n,sum=0,m;
printf("Enter a number:");
scanf("%d",&n);
while(n>0)
{
m=n%10;
sum=sum+m;
n=n/10;
}
printf("Sum is=%d",sum);
return 0;
}
Enter a number:654
Sum is=15
Logical Operators in C
Operator Example Meaning
&& (Logical AND) expression1 && expression2 true only if both expression1 and expression2 are true
|| (Logical OR) expression1 || expression2 true if either expression1 or expression2 is true
! (Logical NOT) !expression true if expression is false and vice versa
#include<stdio.h>
int main()
{
int a=32; //>=35 and(&&) <=100
printf("\nLogical And : %d",(a>=35 && a<=100));
printf("\nLogical Or : %d",(a>=35 || a<=100));
printf("\nLogical Not : %d",!(a>=35));
return 0;
}

, Output
Logical And : 0
Logical Or : 1
Logical Not : 1
2. Program to validate the username and password entered by the user is correct or not using the predefined
username and password.
#include <stdio.h>
#include <string.h>
// use #define macro to define the values for UserName and Password
#define UserName "system"
#define Password "admin@123"
int main ()
{
// declare character type array
char un[50], pass[50];
// take UserName and Password from user
printf ( " Enter the username: " );
scanf (" %s", un);
printf ( " Enter the password: " );
scanf (" %s", pass);
// use if statement and Logical AND operator to validate the condition
if (strcmp (UserName, un) == 0 && strcmp (Password, pass) == 0)
{
printf (" \n The user's credentials are correct. ");
}
else
{
printf ( " \n The user's credentials are incorrect. ");
}
return 0;
}
Output
Enter the username: system
Enter the password: admin@123
The user's credentials are correct.
Relational operators
#include< stdio.h>
int main()
{
int p, q, r;
p = 9;
q = 10;
r = p == q;
printf("%d", r);
