1. What will be the output of the following C code?
#include < stdio.h >
int main()
{
foo();
foo();
}
void foo()
{
int i = 11;
printf("%d ", i);
static int j = 12;
j = j + 1;
printf("%d\n", j);
}
a) 11 12 11 12
b) 11 13 11 14
c) 11 12 11 13
d) Compile time error
2. Assignment statements assigning value to local static variables are executed only once.
a) true
b) false
c) Depends on the code
d) None of the mentioned
3. What is the format identifier for “static a = 20.5;”?
a) %s
b) %d
c) %f
d) Illegal declaration due to absence of data type
4. Which of the following is true for the static variable?
a) It can be called from another function
b) It exists even after the function ends

d) All of the mentioned
5. What will be the output of the following C code?
#include < stdio.h >
void func();
int main()
{
static int b = 20;
func();
}
void func()
{
static int b;
printf("%d", b);
}
a) Output will be 0
b) Output will be 20
c) Output will be a garbage value
d) Compile time error due to redeclaration of static variable

#include < stdio.h >
int main()
{
register int i = 10;

}
a) Depends on whether i is actually stored in machine register
b) 10 10
