Matrix Multiplication in C

Matrix Multiplication in C

In this program, I have discussed about how to multiply two matrices using C programming language.

#include<stdio.h>
int main()
{
 int ar1[50][50],ar2[50][50],mul[20][20],i1,i2,j2,j1,k,l,row1,col1,row2,col2,z,m,n,w;
printf("Enter the number of rows of 1st array: \n");
scanf("%d",&row1);
printf("Enter the number of columns in 1st  array: \n");
scanf("%d",&col1);
for(i1=0;i1<row1;i1++)
{
for(j1=0;j1<col1;j1++)
{
printf("\nEnter an element for %dth row and %dth column of 1st array: ",i1,j1);
scanf("%d",&ar1[i1][j1]);
}
}
printf("\nEnter the number of rows of 2nd array: \n");
scanf("%d",&row2);
printf("\nEnter the number of columns in 2nd  array: \n");
scanf("%d",&col2);
for(i2=0;i2<row2;i2++)
{
for(j2=0;j2<col2;j2++)
{
printf("\nEnter an element for %dth row and %dth column of 2nd array: ",i2,j2);
scanf("%d",&ar2[i2][j2]);
}
}
printf("\n");
if(col1!=row2)
{ printf("Matrix multiplication is not possible !!");
}
else
{ for(k=0;k<col1;k++)
{
for(l=0;l<col1;++l)
{ mul[k][l]=0;
for(w=0;w<col1;w++)
{
mul[k][l]+=ar1[k][w]*ar2[w][l];
}

}
}

for(m=0;m<row1;m++)
{
for(n=0;n<col2;n++)
{ printf("%d  ",mul[m][n]);
}
printf("\n");
}
}
}

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)

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);

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 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);
