Answer all 13 questions:
1. What are Imperative Languages? Is there any difference between Imperative
Languages and Procedural Languages?
2. What is meant by operator associativity and operator precedence? If x, y
and z have values 40, 4 and 10 respectively, what will be the values of x, y and
z after executing the following statement:
z+=(x>20 && x<=50)?x++:x/y;
3. What will be the output of following C code:
#include <stdio.h>
int main() {
int i=1;
if(!i)
printf(“Hin”);
else {
i=0;
printf(“Hellon”);
main();
}
return 0;

typed” language?

methods generally used?
