TEST YOUR C- SKILS

1. What will be the output of the following program?

#include<stdio.h>

int x= 40 // Global Declaration

void main()

{

int x=20; // Local Declaration

printf(“\n%d”, x);

}

2. What will be the output of the following program?

#include<stdio.h>

void main()

{

int x= 40 //Local Variable

{

int x=20; // Most Local variable

printf(“\n%d”, x);

}

printf(“\n%d”, x);

}

Answers:

1. 20, Whenever there is a conflict between a local variable and a global variable, the local variable will get the priority.
2. 20 40, Now both are local variables. In this case the most local variable will get the priority.

a) 264 b) 265 c) 266 d) 267









ANSWERS:

1. b
   

(15*2) + (8/2) =34, (6*2) + (12/2) =18 Hence (5*2) + (40/2)=30

2. c
   

See the difference between the numbers outside the brackets and multiply the result by 2.

3. a
   

514/2 +1=258, 258/2 +1=130, 130/2 +1=66, 66/2 +1=34

4. c
   

See the horizontal rows. 15+7-10= 12. Therefore 25+5-7=23

5. d
   

8*2+1=17, 17*2-1=33, 33*2+1=67, 67*2-1=133,133*2+1=267.
