printf("\n\nEnter the limit\t:");
scanf("%d",&n);
printf("\nThe prime numbers within the given limit:\n");
for(i=1;i<=n;i++)
{
flag=0;
for(j=2;j<=i/2;j++)
{
if(i%j==0)
{
flag=1;

void main()
{
float a,b,c,d,temp,r1,r2;
printf("\nEnter the value of a\t:");
scanf("%f",&a);
printf("Enter the value of b\t:");
scanf("%f",&b);
printf("Enter the value of c\t:");
scanf("%f",&c);

d=((b*b)-(4*c*a));

if(d==0)
