What if we put two arguments in while loop condition seperated by' , ' in clanguage

Answer 1

If you use comma as the separator of the expressions then only the expression following the last comma will be evaluated as loop condition, at least that's how I see from a quick test : )

#include <stdio.h>

int main()
{
int a = 0, b = 1;

// <a> is ignored, only <b> is evaluated
// try with "while(b, a)" to see difference.
while(a, b)
{
puts("Yes it works!");
break; // prevent infinite loop
}
return 0;
}

Answer 2

it can be dont in two ways

while(a<b&&c<b)
{}

while(a<b||a>c)
{}

In the above case its AND joint and in the other one its a OR joint
