C Program for FUNCTION OF COUNT THE INTEREST

float si(float,float,float);

void main()

{

          float p=0,r=0,n=0,k=0;

          clrscr();

          printf("ENTER THE PRINCIPAL: ");

          scanf("%f",&p);

          printf("ENTER THE RATE OF INTEREST: ");

          scanf("%f",&r);

          printf("ENTER THE PERIOD: ");

          scanf("%f",&n);

          k=si(p,r,n);

          printf("THE SIMPLE INTEREST IS %f",k);

          getch();

}

float si(float p,float r,float n)

{

          float k=0;

          k=(p*r*n)/100;

          return(k);

}

OUTPUT :

ENTER THE PRINCIPAL : 10000

ENTER THE RATE OF INTEREST : 5

ENTER THE PERIOD : 1

THE SIMPLE INTEREST IS 600.00
