Question

I want to print both Hello and world.
so what should be the “condition” so that the following code snippet prints HelloWorld

if "condition"
printf ("Hello");
else
printf("World");

Answer 1

It doesn’t work that way… if/else is one or the other. Not both.

If you want to do more than one thing conditionally it has to be something like:

int i =2;
if (i == 2)
    printf("Hello");
if (i > 0)
    printf("World");

These are concurrent ifs and the same variable will be evaluated each time you hit one. In this case you’ll get HelloWorld because both conditions are true.
