C program to calculate Volume of sphere

#include int main()
{
float r,vol=0; float pi=3.14;
printf("Enter the value for radius:"); scanf("%f",&r);
vol=(4*pi*r*r*r)/3;
printf("The volume of sphere is=%f\n",vol); return 0;
}
------------------------------*-----------OUTPUT----------------*------------------------

6. C program to find Pythagoras Theorem

#include #include

int main()
{
//Pythagoras theorem float a,b,c;
printf("Enter the value for a and b\n"); scanf("%f%f",&a,&b);
c=sqrt(a*a+b*b);
printf("The final answer is:%f",c); return 0;
}
------------------------------*-----------OUTPUT----------------*------------------------

2. Scientific problem solving using decision making and looping.

1. Write a C program to find largest among three number

Algorithm:
Step 1: Start.
Step 2: declare num1, num2, num3 Step 3: print Enter three numbers Step 4: read num1, num2, num3.
Step 5: if(num1>num2 && num1>num3)
Print num1 is largest else if(num2>num3)
Print num2 is largest else Print num3 is largest
Step 6: if(num1Print num1 is smallest else if(num2Print num2 is smallest else Print num3 is smallest
Step 7: Stop.
Source Code #include #include int main()
{

int num1,num2,num3; //variable declaration printf("Enter three numbers\n");

scanf("%d %d %d",&num1,&num2,&num3);

//Takse three input num1, num2, num3 from user

//check largest

if(num1>num2 && num1>num3){

//check whether num1 is largest than num2 and num3 printf("%d is the largest number\n",num1);

}//if it is true this statement is displayed else if(num2>num3){
//when it is false then check num2 or num3 large printf("%d is the largest number\n",num2);
//when it is true this statements is displayed

}

else{

printf("%d is the largest number\n",num3);

}//all statements are false this statement is displayed

//check smallest

if(num1

//check whether num1 is smaller than num2 and num3 printf("%d is the smallest number\n",num1);

}//if it is truen this statement is displayed
else if(num2

//when it is false then check num2 or num 3 small

printf("%d is the smallest number\n",num2);//when it is true this statements is displayed

}

else{

printf("%d is the smallest number\n",num3);

}//all statements are false this statement is displayed getch();

return 0;

}
