Program 1:
#include <stdio.h>
int main( )
{
float x;
while (x $\ge$ 5)
Printf ("%d",x);
}
Program 2:
# include <stdio.h>
int main ( )
{
int temp,_temp2;
@_/ / Hello World
return 0;
}
Which of the above gives lexical error ?

• A. Only Program 2
• B. None of these
• C. Only Program 1
• D. Both Program 1 and Program 2
