C Program to calculate roots of quadratic equations

C Program to calculate roots of quadratic equations
This is a simple C program to calculate roots of quadratic equations.A function sqrt() is used in this program to find the square root.Also, we will have to include the math.h header.





#include
#include
main()
{
int a,b,c,d;
float root1,root2;
printf("Enter the values of a,b,c");
scanf("%d%d%d",&a,&b,&c);
d=b*b-4*a*c;
root1=((-b)+sqrt(d))/(2*a);
root2=((-b)-sqrt(d))/(2*a);
printf("root1=%f and root2=%f",root1,root2);
}

A program in C++,to calculate the average of two numbers, which are entered by the keyboard while the execution of the program. Try to understand the program; #include &lt iostream &gt using namespace std; int main() {     float num1,num2,average,sum;     cout << "Enter the first number:";     cin >> num1;     cout << "Enter the second number:";     cin >> num2;     sum=num1+num2;     average=sum/2;     cout << "The sum of the two numbers is:"<< sum<<"\n"<<"The average of the two numbers is:" << average; return(0); } Explaination: The new file header used here in this C++ program is the #include .

Finding the arithmetic operators

Below is a very simple program to find the arithmetic operator. Please feel free to put a comment if need an explanation. #include #include void main()   {     float a1,a2;     char operator;     printf("\n Enter the values of a1 operator a2\n");     scanf("%f%c%f",&a1,&operator,&a2);     switch(operator)      { case '+': printf("%.2f",a1+a2); break; case '-':  printf("%.2f",a1-a2);  break; case '*':  printf("%.2f",a1*a2); break; case '/':  if(a2==0)  printf("error\n");  else  printf("%.2f",a1/a2);  break; default: printf("unknown operatotr\n"); break;      }    }
