goto statement problem. reply fast.

I have done some operation, and want to repeat same operation again at users choice. but its not working properly. I am using goto statement.

void main()

{ float rs, p;

    char z;

clrscr();

    rep :

    printf("\nEnter the value rs");

    scanf("%f",&rs);

    p=rs*100;

    printf("\n\npaisa =%2.f ",p);

    printf("\n do you want to access operation once again? press y/n");

    if(z='y') /* i have check this also by if(z=='y') but its not working. */
        goto  rep;
getch();

}

problem happening is either its repeating again and again.. or its not repeating according to users choice.

try this...

void main()
{
    float rs,p;
    char z='y';
    clrscr();
  while(z=='y')
   {
    printf("\nEnter the value rs");
    scanf("%f",&amp;rs);
    p=rs*100;
    printf("\n\npaisa =%2.f ",p);
    printf("\n do you want to access operation once again? press y/n");
    scanf("%c",z); 
    }
getch();
