C Programming

In the following loop construct, which one is executed only once always.

for(exp1; exp2; exp3)

• exp1

• exp3

• exp1 and exp3

• exp1,exp2 and exp3

The continue statment cannot be used with

• for

• while

• do while

• switch

goto can be used to jump from main to within a function?

• true

• false

• -

• -

Which loop is guaranteed to execute at least one time.

• for

• while

• do while

• none of the above

A labeled statement consist of an identifier followed by

• :

• ;

• ?

• =

c = (n) ? a : b; can be rewritten asexp1 ? exp2 : exp3;

• if(n){c = a;}else{c = b;}

• if(!n){c = a;}else{c = b;}

• if(n){c = b;}else{c = a;}

• None of the above

What will be the output of the following C code?

#include <stdio.h>

int main()

{

while ()

printf("In while loop ");

printf("After loop\n");

}

• In while loop after loop

• After loop

• Compile time error

• Infinite loop

What will be the output of the following C code?

#include <stdio.h>

int main()

{

do{

printf("In while loop ");

}while (0);

printf("After loop\n");

}

• In while loop

• In while loop after loop

• After loop

• Infinite loop

What will be the output of the following C code?

#include <stdio.h>

int main()

{

int i = 0;

do {

i++;

printf("In while loop\n");

} while (i < 3);

}

• In while loop

  In while loop

  In while loop

• In while loop

  In while loop

• Depends on the compiler

• Compile time error

#include <stdio.h>

int main()

{

int i = 0;

do {

i++;

printf("in while loop\n");

} while (i < 3);
