C program to find GCD of two or three numbers using function

 C program to find GCD of two or three numbers using function

 In this program, I have discussed about how to find the GCD of two or three number using function in the C programming language.

The full form of GCD is greatest common divisor. If we consider three number 10,15,20 then the GCD of these three number will be 5.

int hcf2(int,int);
int hcf3(int,int,int);
 int main()
{ int a,b,c,d,hc1,hc2,n;
printf("Enter the number of numbers whose HCF you want to calculate (2<=number<=3) \n");
scanf("%d",&n);
switch(n)
{ case 2:
printf("Enter two numbers \n");
scanf("%d%d",&a,&b);
hc1=hcf2(a,b);
printf("The HCF of %d and %d is %d \n",a,b,hc1);
break;
case 3:
printf("Enter three numbers \n");
scanf("%d%d%d",&a,&b,&c);
hc2=hcf3(a,b,c);
printf("The HCF of %d, %d and %d is %d \n",a,b,c,hc2);
break;
}
}
int hcf2( int k1,int k2)
{
int i,h1=0;
 for(i=1;i<=k1;i++)
{
if(k1%i==0&&k2%i==0)
{
if(i>h1)
{h1=i;
}
}
}
return h1;
}
int hcf3( int k1,int k2,int k3)
{int i,h2=0;
 for(i=1;i<=k1;i++)
{
if(k1%i==0&&k2%i==0&&k3%i==0)
{
if(i>h2)
{h2=i;
}
}
}
return h2;
}

C program to check strong number

C program to check strong number

 In this program, I have discussed about how to check strong number.

145 is called a strong number because the sum of factorial of its digits is equal to that number, i.e., 1!+4!+5!=145.

Strong numbers are also called as special numbers.

#include<stdio.h>
int fact(int);
int main()
{ int n,i,j,sum=0,k,num;
printf("Enter a number :");
scanf("%d",&n);
num=n;
while(n!=0)
{ k=n%10;
j=fact(k);
sum+=j;
n=n/10;
}
if(sum==num)
{ printf("Strong Number");
}
else
{ printf("Not a strong number");
}
}
int fact( int g)
{ int l=1,i;

C program to calculate gross salary of a person. 

D.A= 74%of salary.
H.R.A=15%of salary.
Salary=D.A+H.R.A.

-----------------------------------------------------------------------------------------
#include<stdio.h>
void main()
{float salary,da,hra,income;
printf("Enter the salary:\n");
scanf("%f",&salary);
da=.74*salary;
hra=.15*salary;
income=salary+da+hra;
printf("The income is:%f \n",income);
}

C Program to calculate electric bill of a consumer- BASIC WAY

C Program to calculate electric bill of a consumer- BASIC WAY

In this program I have discussed about the basic C Program to calculate electric bill of a consumer.

Here I have assumed that the the rate of per unit of current consumed is fixed at Rs 3.75. If the rate is made to be variable then the program will change.

--------------------------------------------------------------------

#include<stdio.h>
void main()
{ float prev,curr,net,bill;
printf("Enter the previous reading and the current reading:\n");
scanf("%f%f",&prev,&curr);
net=curr-prev;
bill=net*3.75;
printf("Your bill is: %f \n",bill);
}

C Program to Calculate Area and Perimeter of Rectangle And Area and Circumference of Circle

C Program to Calculate Area and Perimeter of Rectangle And Area and Circumference of  Circle

In this program I have discussed about the C Program to Calculate Area and Perimeter of Rectangle And Area and Circumference of  Circle.

Area of a rectangle= Length * Breadth

Perimeter of a rectangle= 2*(length+breadth)

Area of a circle= 3.14* (Radius)^2

Perimeter of a circle= 2* 3.14*radius

-------------------------------------------------------------------------------------------

#include<stdio.h>
void main()
{float rad,length,breadth,area1,area2,peri,circu;
printf("Enter the length and breadth of the rectangle:");
scanf("%f%f",&length,&breadth);
area1=length*breadth;
peri=2*(length+breadth);
printf("The area of the rectangle is %f \n",area1);
printf("THe perimeter of the rectangle is %f \n",peri);
printf("Enter the radius of the circle:");
scanf("%f",&rad);
area2=3.14*(rad*rad);
circu=2*3.14*rad;
printf("The area of the circle is %f \n",area2);
printf("THe circumference of the circle is %f \n",circu);
}

C Program to Find the Largest Number Among Three Numbers

C Program to Find the Largest Number Among Three Numbers

In this program I have discussed about the C Program to Find the Largest Number Among Three Numbers..

Here I have used the ternary operator (?) to solve the program.

---------------------------------------------------------------------

#include<stdio.h>
void main()
{ int a,b,c;
printf("Enter three numbers: ");
scanf("%d%d%d",&a,&b,&b);
int p=a>b?a:b;
int q=c>p?c:p;
printf("The large number is %d \n",q);
}

C Program to convert Celsius to Fahrenheit

C Program to convert Celsius to Fahrenheit

In this case, I have discussed about the C Program to convert Celsius to Fahrenheit.

The relation between Celsius and Fahrenheit is,,
C/5= (F-32)/9
where C = Temperature in degree celsius  and
           F = Temperature in degree fahrenheit.

----------------------------------------------------------------------------------


#include<stdio.h>
void main()
{ 
float fah,cen;
printf("Enter the fahrenheit temerature:");
scanf("%f",&fah);
cen=(5*fah-160)/9;
printf("The celcius temperature is %f",cen);
}

C program to swap two numbers without using a third variable

C program to swap two numbers without using a third variable

 In this program, I have discussed about the C program to swap two numbers without using a third variable.

Swap means to interchange the values of two variables.

Here I have not used a third variable to swap the two numbers.

----------------------------------------------------------------------------------------------------------------

#include<stdio.h>
void main()
{ int a,b;
printf("Enter two numbers: ");
scanf("%d%d",&a,&b);
a=a+b;
b=a-b;
a=a-b;
printf("the two numbers are: \n");
printf("%d \n",a);
printf("%d \n",b);
}

C Program to Swap Two Numbers

C Program to Swap Two Numbers

In this program I have discussed about the C Program to Swap Two Numbers .

We have used a third variable here to swap the two numbers.

Swap means to interchange the values of two variables.

#include<stdio.h>
void main()
{ int a,b,c;
printf("Enter two numbers");
scanf("%d%d",&a,&b);
c=a;
a=b;
b=c;
printf("The first number %d \n",a);
printf(" The second number %d ",b);
}
