Code:
#include <stdio.h>
int main()
{
int choice;
do
{
printf("Enter your choice: ");
scanf("%d", &choice);
switch (choice)
{
case 1:
{
printf("Hello World\n\n");
break;
}
case 2:
{
printf("Hello World2\n\n");
break;
}
case 3:
{
printf("Hello World3\n\n");
break;
}
default:
{
return 0;
break;
}
}
} while (choice >= 1 && choice <= 3);
return 0;
}
1) Like a this program, at first, when you enter unmeaning values (like * - / + . , etc.) as choice it is stopping as it should be.
2) However, at first when you enter as choice 1,2 or 3 and then enter unmeaning values (like * - / + . , etc.) it is starting to loop forever.
Although at first isn't a thing like this, Why is it happening at second?
