 Roots of Quadratic -------------------------------------------------------------------------------- Description : To find real roots for a quadratic equation!! Code : //PROGRAM TO CALCULATE THE REAL ROOTS OF A QUADRATIC EQUATION. #include #include #include void main() { clrscr(); int a,b,c; float d,r1,r2; printf(" ENTER THE VALUE OF A,B,C TO FORM THE QUADRATIC EQUATION AX^2+BX+C:
); printf("A="); scanf("%d",&a); printf(" B="); scanf("%d",&b); printf(" C="); scanf("%d",&c); d=(b*b)-4*a*c; if(sqrt(d)<0) printf(" NO REAL ROOT EXISTS:"); else { printf(" REAL ROOTS EXIST:"); r1=((-b)+sqrt(d))/(2*a); r2=((-b)-sqrt(d))/(2*a); printf(" THE REAL ROOTS OF THE EQUATION "); printf("%d",a); printf("x^2+"); printf("%d",b); printf("x+"); printf("%d",c); printf(" ARE :%f",r1); printf(" AND %f",r2); } getch(); }
