Program to find GCD of two or three numbers in C

Program to find the GCD of three numbers in C

 In this program, I have discussed about how to find the GCD of three numbers in C.

#include<stdio.h>
int main()
{ int a,b,c,d,hcf=0,i;
printf("Enter three numbers: \n");
scanf("%d%d%d",&a,&b,&c);
for(i=1;i<=a;i++)
{
if(a%i==0&&b%i==0&c%i==0)
{
if(i>hcf)
{hcf=i;
}
}
}
printf("HCF is %d ",hcf);
}

C Program to Find Factorial of a Number

C Program to Find Factorial of a Number

 In this program, I have discussed about the C Program to Find Factorial of a Number.

Example of factorial of a number : 5: 1*2*3*4*5= 120 (answer)

#include<stdio.h>
int main()
{ int n,k=1,i;
printf("Enter a number");
scanf("%d",&n);
for(i=1;i<=n;i++)
{ k+*i;
}

C program to print the series (1/2)+(3/4)+(5/6)

C program to print the series (1/2)+(3/4)+(5/6)+ (7/8) +  (9/10)

 In this program, I have discussed about the C program to find the sum of the series which I have shown above. 

Series programs is very important for your academic exams. Terms in the brackets will be solved first and then "+" terms are solved.

#include<stdio.h>
int main()
{float n,i,j,k=0;
for(i=1,j=2;i,j<=10;i+=2,j+=2)
{k=k+(i/j);
}
printf("%f",k);
}

Area of Triangle using Heron's Formula in C

Area of Triangle using Heron's Formula in C

 In this program, I have discussed about the Area of Triangle using Heron's Formula in C.

Heron's formula states that if a, b,c are the three sides of a triangle then the area of that triangle will be equal to [ area=sqrt(s*(s-a)*(s-b)*(s-c))] , where s=(a+b+c)/2.

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


#include<stdio.h>
#include<math.h>
void main()
{
 float a,b,c,area,s;
printf("Enter the value of a,b,c");
scanf("%f%f%f",&a,&b,&c);
s=(a+b+c)/2;
area=sqrt(s*(s-a)*(s-b)*(s-c));
printf("The area of the triangle is %f \n",area);

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);
