WAP to take three sides of a triangle as input and print if the triangle is equilateral ,isosceles , scalene.

program code:

#include<stdio.h>

int main()

 {

  int a,b,c;

  printf("Enter a sides of triangle :\n");

  scanf("%d%d%d",&a,&b,&c);

  if((a==b) && (b==c))

   {

    printf( "\nThe triangle formed by %d,%d,%d  sides is equilateral",a,b,c);

   }

  else if((a==b) || (b==c) || (a==c))

   {

     printf( "\nThe triangle formed by %d,%d,%d  sides is isosceles",a,b,c);

   }

 else

    {

      printf( "\nThe triangle formed by %d,%d,%d  sides is scalene",a,b,c);

     }

return 0;

}

Output:-

cse@ubumtu:~$gcc triangle.c - o triangle

cse@ubuntu:~$./triangle

Enter a sides of triangle :

2

4

6

The triangle formed by 2,4,6  sides is scalene.

 Enter a sides of triangle :

2

2

2

The triangle formed by 2,2,2  sides is equilateral

Enter a sides of triangle :

2

2

3

The triangle formed by 2,2,3  sides is isosceles.

c program to print sum of the digits of the given number

c program to print sum of the digits of the given number

 In this program we have to given input a number and we have to find the sum of the digits of the given number and show the result in the output screen. This program is basically used for basic concept who are not known in the c programming.   

program code:-

#include<stdio.h>

int main()

 {

  int n,r,sum,m;

  printf("Enter a number :\n");

  scanf("%d",&n);

  m=n;

  sum=0;

  while(n>0)

    {

      r=n%10;

      sum=sum+r;

      n=n/10;

    }

printf("\n sum of digits of %d is %d ",m,sum);

return 0;

}

Output:-

cse@ubuntu:~$gcc sumdig.c - o sumdig

cse@ubuntu:~$./sumdig

Enter a number : 356

sum of digits of 356 is 14

C PROGRAM TO PRINT RADIUS AND VOLUME OF SPHERE

C PROGRAM TO PRINT RADIUS AND VOLUME OF SPHERE

Program code:-

#include<stdio.h>

#include<math.h>

#define PI 3.14

int main()

 {

   float radius,sa,vol;

   printf("\nEnter radius of sphere:\n");

   scanf("%f",&radius);

   sa=4*PI*pow(radius,2);

   vol=(sa*PI*radius)/3;

   printf("\nvolume of sphere of %f radius is %f ",radius,vol);

   printf("\nsurface of sphere of %f radius is %f",radius,sa);

return 0;

}

Output:-

tsp@ubuntu:~$gccsphere.c - o sphere

tsp@ubuntu:~$./sphere

Enter radius:

2

volume of sphere of 2.000000 radius is 25.120001

surface area of sphere of 2.000000 radius is 50.240002
