Question

Consider the following C code:
include <stdio.h>
int fun()
{
static int num=25;
return num--;
}
int main()
{
for(fun( ); fun();fun())
printf("%d", fun( ));
return O;
}
The sum of the values printed by the above program will be

yes 100     how to solve these types of questions

first time when for loop is executed it become

1. for(fun=25;fun()//here decrement will take place so now value is 24;fun())

   printf ("%d",fun()   //here decrement will take place so now value is 23)

2. now condition check so value become 22

3 now again for loop for(fun=22;fun()  //here decrement will take place so now value is 21; fun())

 printf ("%d",fun()   //here decrement will take place so now value is 20)

 

nd so on

Answer 1

It won't do anything , it will have compilation error.

Used : instead of ;

If we consider it without errors , equivalent while loop can be written as :-

fun(); //initialization

while(fun()//termination condition when fun() gets 0) {

print("%d",fun());

fun();

}

which will print :-

But we are performing 4 fun() in each iteration..so the sequence should be 22,18,14,10,6,2, right?

4 . How? initialization happens only once in for loop
