 Q1. Write a program to display percentage , average and grade by taking input as marks?

(A)   #include<stdio.h>

          void main ()

       {

float m1,m2,m3;

float per,avg;

float total;

printf(" enter the marks of MATHS ");

scanf("%f", &m1);

printf(" enter the marks of CPNM ");

scanf("%f", &m2);

printf("enter the marks of CHEMISTRY ");

scanf("%f", &m3);

total= m1+m2+m3;

printf("\n the total mark is %.2f ",total);

per = (total/300)*100;

avg = (total/3);

printf("\n the percentage mark is : %.2f ", per);

printf("\n the average mark  is: %.2f", avg);

if(per>=80) printf("\n Grade : A");

else if(per>=60) printf("\n Grade : B");

else if(per>=40) printf("\n Grade : C");

else if(per<40) printf("\n Fail ");

        }

Q1 . Write a program to compute the roots of quadratic equation using if else statement ?

(A)   #include<stdio.h>

        #include<math.h>

          void main()

    {

  int a, b, c;

 float disc, root1, root2, real, imag;

printf("Enter the values of a, b and c\n");

 scanf("%d %d %d", &a, &b, &c);

 disc = ((b*b)-(4*a*c));

  if(disc > 0)

{

root1 = (-b + sqrt(disc))/(2*a);

root2 = (-b - sqrt(disc))/(2*a);

  printf("Roots are real and                complex\n");

{  

printf("num1 is smaller than num2");  

}

return 0;
